Connecting the Cables to the Sun Netra t 100 and the
Sun Netra t 105

This section describes how to connect the hardware components to the network.

Before following the instructions in this section, make sure that you have installed the Sun Netra t 100 or the Sun Netra t 105 system into a rack or cabinet.


Step 1 Connect the power cord or cords (see
Figure A-8 and Figure A-9 in the next section, "Connecting the Power Cord" ).

Step 2 Connect the system to at least one Ethernet hub. You can connect to a maximum of two.

Step 3 Connect at least one serial device. For more information, see "Setting Up Serial Connections".

Step 4 If you want to use the Sun Netra t1 system's remote monitoring and management facilities, make sure that you use the port labeled Serial A/LOM.

Step 5 If you intend to configure the Sun Netra t1 system directly from a dumb terminal or a Sun workstation, insert the serial cable into the DB25 adapter supplied (see Figure A-6 and Figure A-7).

Step 6 When you have done this, plug the adapter into the DB25 serial connector on the terminal or Sun workstation.

Step 7 If you need to connect the Sun Netra t1 system to an external SCSI device, you must use the SCSI cable supplied with that device.

Step 8 The Sun Netra t1 external SCSI bus is compatible with narrow (8-bit) or wide (16-bit) single-ended SCSI devices.

Step 9 Go to the "Power and Grounding" section to power the system up.

Step 10 For information about the patches you need to apply, see the patches section below.

Connecting the Power Cord

This section contains diagrams showing how the DC connectors for the Sun Netra t 100 and the AC connector for the Sun Netra t 105 connect to the system.


Caution Sun products are designed to work with single-phase power systems having a grounded neutral conductor. To reduce the risk of electric shock, do not plug Sun products into any other type of power system. Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.


Caution Your Sun product is shipped with a grounding type (three-wire) power cord or cords. To reduce the risk of electric shock, always plug the cords into a grounded outlet.

Figure A-9:
Model 105: Connecting the AC Power Cord

Setting Up Serial Connections

To perform the initial configuration when you install the Sun Netra t1 system, and for on-going monitoring and management of the system, you need to use at least one of the serial ports on the system rear panel. You can connect either or both serial ports to any of the following devices:


Note The Serial A/LOM port cannot be used for binary data transfers. To perform anything other than ASCII transfers, use the port labeled Serial B.

Cross-Overs for Connecting to a Terminal Server

The serial ports on the Sun Netra t1 server are DTE ports. If you are connecting them to other DTE ports, then the cabling between the devices you are connecting to each other must perform a cross-over.


Note Do not use the Serial A/LOM port for modem connections. The DTE signal on this port changes temporarily to DCD when the Sun Netra t1 LOM device reports an event on the serial port. This can result in the loss of a modem connection. If you are connecting the Serial A/LOM port to a Terminal Server, disable modem control on the Terminal Server port.

The pins in the Sun Netra t1 serial ports correspond with the pins in the RJ-45 ports on the Asynchronous Serial Interface Breakout Cable supplied by Cisco for use with the Cisco L2511 Terminal Server. This Cisco cable performs the pin cross-overs listed in Table A-4. This means that, if you are using a Cisco L2511 Terminal Server (and you are connecting the Sun Netra t1 system to it using the Asynchronous Serial Interface Breakout Cable), you do not need to do any pin cross-overs yourself. You can use the straight-through RJ-45 patch cable supplied with the Sun Netra t1 system to connect directly to the Breakout Cable or to connect directly to a patch panel that is then connected to the Breakout Cable (see Figure A-10).


Note For other terminal servers, check the manufacturer documentation to see if the pin configuration used in the serial ports matches the pin configuration in the Sun Netra t1 serial ports. If it does not, then you must make a cable that takes each pin on one of the
Sun Netra t1 serial ports to the corresponding pin in the serial port of the terminal server connection.

Using a DB25 Adapter for Your Serial Link

The pinouts are identical for both of the RJ-45 serial ports on the Sun Netra t1 system. To connect to a UNIX TIP session or a vt100 terminal, you need to use either the DB-25 (25-Pin DSUB Male to 8-POS RJ-45 Female) adapter that is supplied by Sun (part no. 530-2889) with your system, or an alternative adapter that performs the same pin cross-overs. The Sun-supplied DB25 adapter enables you to connect to any Sun system. The cross-overs that it performs are listed in Table A-5.


Note If you need to set up a modem connection to the Sun Netra t1 system, you must use the port labeled Serial B. The Serial A/LOM port does not assert the required constant DTR signal.


Note When viewed from the rear of the Sun Netra t1 system, pin 1 of the RJ-45 serial port is on the left and pin 8 is on the right.

Settings for the Serial Connections

The settings you must use for a serial connection are listed in Table A-7. If you need to perform binary data transfers (that is, transfers of anything more than simple ASCII character streams), use the Serial B port. Communication on the Serial A/LOM port is subject to interruption by the Lights-Out Management (LOM) device.

Power and Grounding

This section describes power and grounding requirements and instructions for connecting your
Sun Netra t 100 and Sun Netra t 105 to the network. This section contains the following sections:

Warnings

Observe the following warnings before connecting and powering the server hardware.


Warning Only trained and qualified personnel should be allowed to install or replace this equipment.


Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.


Warning A voltage mismatch can cause equipment damage and may pose a fire hazard. If the voltage indicated on the label is different from the power outlet voltage, do not connect the chassis to that receptacle.


Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Connecting the Sun Netra t 100 and the Sun Netra t 105

The Sun Netra t 100 is DC-powered, and the Sun Netra t 105 is AC-powered. Refer to the
Sun Netra t1 System User and Administration Guide that shipped with the product for DC and AC source site requirements, overcurrent protection, grounding instructions, and power cord installation instructions. The Sun system must be connected to the power source and grounded per Sun installation instructions.

Grounding Sun Netra t 100 and Sun Netra t 105 Hardware

This section contains information about grounding your equipment.


Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.


Figure A-14: Earth Ground Symbol



Note The hardware for this ground connection is not provided by Cisco. Figure A-14 shows a typical earth ground symbol. The installer is responsible for obtaining the necessary hardware and making the connection to earth ground.

Earth ground connections are made in several ways depending upon the equipment. All AC-powered equipment is connected to earth ground over the ground conductor within the power cable. The DC-powered equipment provides earth ground connections using grounding studs or through the mounting hardware used to secure the equipment to the frame. The use of toothed lock washers are recommended for securing all of the equipment (AC or DC) to the equipment frame.

Powering Up and Configuring for the First Time

The section contains the following:

Read the instructions in this section thoroughly before you start for the first time.

To perform the initial configuration of the Sun Netra t1 system, set up a serial connection via the port labeled Serial A/LOM on the Sun Netra t1.

Make sure that you have the Sun Netra t1 power cord or cords connected. With the system connected to the power supply but not powered up, and with a serial connection to the Serial A/LOM port and a connection to at least one Ethernet hub, follow the instructions below:


Step 1 At the lom> prompt, type the following command to power on the system:

poweron

During booting, the system prompts for the information requested in steps 3 through 19. The system will boot after the information has been entered.

Step 2 The first question the system asks you is what language you want it to use when it prompts you for the information it needs. Specify a language.

Step 3 Next specify your locale.

Step 4 Specify the type of terminal you are using to communicate with the Sun Netra t1.

Step 5 Specify a Host Name for the system.

Step 6 When asked if you are connected to the network by a Sun Solaris-supported Ethernet card, answer Yes.

Step 7 Specify which of the Ethernet ports you intend to use as the primary Ethernet connection.

Step 8 For the port labeled Net0, specify hme0. For the port labeled Net1, specify hme1.

Step 9 Specify a valid IP address for the system.

Step 10 Specify the Name Service you want the system to use.

Step 11 Specify the name of the Domain that the system will be a part of.

Step 12 Specify whether you want the system to search the network for a Name Server or whether you want it to use a particular Name Server.

Step 13 If you selected to use a particular Name Server, specify the Host Name and IP address of the Name Server.

Step 14 Specify whether the system is to be part of a subnet.

Step 15 Specify a Netmask for the system.

Step 16 Confirm the information you have typed in and, when prompted, provide the time and date information the system needs.

Step 17 When prompted, specify a password (if any) for users logging in as root.

Step 18 When asked if you want the system to perform Automatic Power Saving Shutdown, specify No. If you specify Yes, the system will automatically put itself into Standby mode after a period of idleness.


Configuring via a Terminal Server

To access the Sun Netra t1 system from a Sun workstation via a Terminal Server, open a Terminal Session on the Sun workstation, and type:

# telnet IP address of Terminal Server port number

For example, for a Sun Netra t1 system connected to port 10000 on a Terminal Server whose IP address is 192.20.30.10, you would type:

# telnet 192.20.30.10 10000

Configuring from a Terminal or Workstation

To access the Sun Netra t1 system from a terminal, set up a connection between the terminal and the Sun Netra t1 system.

To access the Sun Netra t1 system from a Sun workstation directly connected to the system, set up the connections between the devices and run a terminal session. Note, however, that before you can connect to the Sun Netra t1 system Serial A/LOM port from a Sun workstation, you must edit the hardwire line in the etc/remote file. The default is:

hardwire:\:dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D

You must replace the letter b ( after term/ and before the third colon) with the letter a, so that the line looks as follows:

hardwire:\:dv=/dev/term/a:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D

Using the Power (On/Standby) Switch


Caution The power switch (on the rear panel of the Sun Netra t1 system) is not an On/Off switch; it is an On/Standby switch. It does not isolate the equipment.

The system (On/Standby) switch of the Sun Netra t1 system is a rocker switch, shown in Figure A-15 and Figure A-16. It controls only low-voltage signals; no high-voltage circuits pass through it. This means that the main method of connecting or disconnecting power is by inserting or removing the power supply cords. The system contains no integral circuit breakers. To isolate it, you must break all connections to it. If you do not do this by removing the power supply cords, you must instead open all external circuit breakers.

The symbols on the switch are as follows:

On---Press this to apply power to the system.

Standby---Press this to put the system into standby mode.

Monitoring and Maintenance

This section provides reference material designed to supplement the installation section. The section contains the following sections:

Using the Lights-Out Management Facility

The Sun Netra t1 includes a management facility that allows you to detect and respond quickly to problems with the power supply unit or fans. It is particularly useful for monitoring servers remotely that are deployed in a "lights out" environment. But you can also use it to perform quick onsite management tasks via a local serial connection.

This management facility is provided by a device on the Sun Netra t1 motherboard called the Lights-Out Management (LOM) device and by software that is pre-installed on your system during manufacturing.


Note If you install new system software onto the Sun Netra t1 and you want to continue using the Lights-Out Management facility, you must re-install the LOM software. A CD containing the software is available from your Sun Enterprise Services representative (part number: X6972A).

You can use the LOM facility to:

You can also configure the LOM device on the Sun Netra t1 to perform an automatic system restart in the event of a lockup.

LOM Device Reporting

The LOM device monitors the status of the fans and the power supply even when the system is powered down (the LOM device operates on standby power). If it detects a fault, it turns on the Fault LED on the system front and rear panels and stores a report in an event log that resides in memory on the LOM device itself. What it does next depends on whether the operating system is running with a daemon called lomlited enabled:

When the Operating System is Running and the lomlited Daemon Is Installed and Running

When the operating system is running and the lomlited daemon is enabled, the LOM device is monitored by the lomlited daemon. This daemon sends LOM event reports to syslogd giving them the identifier string lomlited. The syslogd handles them in the way it is configured to handle event reports (by default, it sends them to the console and stores them in /var/adm/messages).

The lomlited daemon is started by an rc script. The daemon is stored in /etc/init.d.

When the lomlited Daemon Is Not Running

The lomlited daemon does not monitor the LOM device when:

In any of these circumstances, when the lomlited daemon is not running and an event affecting the fans or power supply occurs, the LOM device takes control of the Serial A/LOM port and sends an event report onto that port. When it has sent the report, the LOM device relinquishes control of the serial port. Note that this can interfere with communication on the Serial A/LOM port (see note below).


Note LOM reports that occur when the lomlited daemon is not running can interfere with communication on the Serial A/LOM port. If you do not have the lomlited daemon installed and enabled then, to prevent the LOM from interrupting serial communication, either use the Serial B port as your console port or turn off LOM event reporting (see "Stopping the LOM from Sending Reports to the Serial A Port When the Daemon Is Not Running" section below).

Capturing LOM Event Reports Passively on the Serial A/LOM Port

To monitor LOM events as they occur, keep a terminal connected to Serial Port A.

For information about using LOM commands to interrogate the LOM device, see "Interrogating the LOM and Using It to Power Up or Reset the System".

Stopping the LOM from Sending Reports to the Serial A Port When the Daemon Is Not Running

LOM reports that occur when the lomlited daemon is not running can interfere with information you are attempting to send or receive on the Serial A/LOM port.

If you do not have the LOM software installed or you have disabled the lomlited daemon, you might want to stop the LOM device from sending reports to the Serial A/LOM port.

# lomctl serialeventsoff
# lomctl serialeventson

Interrogating the LOM and Using It to Power Up or Reset the System

If you want to use the LOM device to power on or off or to reset the system, or if you want to view the LOM event log, you need to connect a terminal to Serial Port A and then put the port into LOM mode. In LOM mode, you can execute LOM commands.

To use the LOM commands, type the LOM escape sequence at a console connected to the Serial A/LOM port. The escape sequence is:

# #.

When you type the LOM escape sequence, the LOM device takes control of the Serial A/LOM port and the lom> prompt appears on your terminal screen. You can type the LOM escape sequence at any time.

Powering the System On and Off

poweron
poweroff

Resetting the System

reset

Checking the Current Status of All Components Monitored by the LOM

To see the current status of all the components monitored by the LOM, type the following at the lom> prompt:

environment

Figure A-17 shows some sample output from the environment command. The Fault LED is on (because Fan 3 is running too slowly). All the Alarms are OFF. Fan 3 is faulty, and one of the DC inputs (in this case, input A) to the power supply unit has failed.

The environment Command Showing Fan 3 and DC Input Supply Faults

Viewing the LOM Device Event Log

To see the event log, type the following at the lom> prompt:

show eventlog

Figure A-18 shows a sample event log display. Note that the first event is the oldest. In this example, the show eventlog command indicates that all the alarms have been set to OFF, that FAN 3 has failed, and that DC input supply A has failed. Also, the system has been put into and then out of standby mode by means of LOM commands, and before thi,s it was reset by means of a LOM command (the reset command).

The only "fatal error" is the fan 3 failure. No other fatal errors have occurred. The PSU "In A" failure is not a fatal error, because it affects a component (the input supply) that is external to the system.

Note Note that the "first fatal error" heading is always present, even when the list of errors is empty.

Shortening the LOM Commands

For a full list of the commands associated with the LOM, see "LOM Commands". You can shorten these commands, but you must observe the following rules:

re

Similarly, co, con, and console are all valid abbreviations of the console command. But power is not a valid abbreviation of the poweron command, because the character sequence `power' is also characteristic of the poweroff command. For a list of the minimum abbreviation permissible for each command, see Table A-8.

LOM Commands

The LOM commands are listed in Table A-8.


Table A-8: LOM Commands
Command Minimum Abbreviation Effect

alarmoff n

alarmof n

Sets alarm n off.
(Where n is 1, 2, or 3.) These three alarms are software flags. Alarm 3 is set to TRUE by the LOM to indicate a system lockup. Alarms 1 and 2 are associated with no specific conditions but are available to be set by your own processes.

alarmon n

alarmon n

Sets alarm n on.
See the description for the alarmoff command.

check

ch

Resets monitoring to report all failures.
If a monitored component has failed, the LOM device does not continue to report the same failure. To check the status of the component, for example, after attempting to fix it, issue the check command. This updates the status of all monitored components.

console

co

Returns control of the serial connection to the console.

environment

en

Displays the status of the fans, the power supply, the alarms, and the Fault LED.

faulton

faulton

Sets the Fault LED to ON.

faultoff

faultof

Displays the current LOM escape sequence.

show

sh

Displays all the information available with the show command.

version

ve

Displays the version number of the LOM device.

Configuring the LOM to Restart the System Automatically After a Lockup

The LOM software pre-installed on the Sun Netra t1 (or available on the LOMlite CD) includes the tsdog utility. The tsdog utility is a watchdog process. It "pats" the LOM device at specified time intervals, and as long as it continues to do this the LOM device takes no action. If however, the system locks up and the LOM device therefore does not receive its usual pat from the tsdog watchdog, then, after a timeout period, the LOM device lights the Fault LED, sends a LOM report, and (if configured to do so) resets the Sun Netra t1 system.

By default, the tsdog watchdog pats the LOM every 10 seconds and the LOM device watchdog timer times out after 40 seconds. When the watchdog timer times out, the LOM reports an event and lights the Fault LED, but it does not by default reset the system.

To make the LOM device reset the system when its watchdog timer has timed out (after not receiving a pat from the tsdog watchdog), you need to edit the LOM configuration file. This file is called lom.conf and is stored in /kernel/drv.

To make the LOM restart the system automatically after a lock-up, edit the wdog_reset line to read:

wdog_reset=1


Note An alternative is to type tsctl hwreset=on at the Sun Solaris prompt. However, if you use this command, you will have to remember to repeat the command, each time you boot the system.

By default, the LOM attempts to disable its watchdog timer if it detects that a break signal has been sent to the system. This prevents it from restarting the system unnecessarily. If you do not want the LOM to attempt to disable its watchdog timer when a break has been sent to the system, edit the disable_wdog_on_break line to read:

disable_wdog_on_break=0

Similarly, by default, the LOM attempts to disable its watchdog timer if it detects that the system has undergone a "panic." If you do not want the LOM to attempt to disable its tsdog watchdog timer after a panic, edit the disable_wdog_on_panic line to read:

disable_wdog_on_panic=0

Alternate LOM Configurations

The LOM device takes its configuration from a file called lom.conf. This is stored in /kernel/drv.

The full list of parameters you can set in this file is given in Table A-9.


Table A-9: LOM Configuration File Parameters
Field Format Effect

wdog_enabled

Boolean

Enables the tsdog watchdog when the LOM driver loads.

wdog_reset

Boolean

Causes the LOM to reset the Sun Netra t1 after a tsdog watchdog timeout.

wdog_alarm3

Boolean

Turns on software alarm 3 when the tsdog watchdog times out.

wdog_timeout

Integer

Sets the timeout for the tsdog watchdog. The value is in seconds. If the system locks up and the LOM device does not receive the expected "pat" from the tsdog watchdog, then, after the timeout period that you specify, the LOM device reports an event, lights the Fault LED, and if configured to do so (see wdog_reset above) resets the Sun Netra t1 system.

serial_events

Boolean

Causes the LOM to report events over the serial connection.

disable_wdog_on_break

Boolean

Causes the LOM to disable its tsdog watchdog if a break signal is detected on the Serial A/LOM port.

disable_wdog_on_panic

Boolean

Causes the LOM to try to disable the LOM watchdog after a system panic.

Each parameter must be on a separate line and must be followed by an equals sign (=) and a value, without spaces. Where the format is Boolean, 1 means true and 0 means false.

Utilities Associated with the LOM Device

There are a number of utilities associated with the LOM device. They are stored in usr/sbin.

For information about using these utilities to perform more advanced monitoring and configuration, refer to the manpages for lomctl(1M), lominfo(1M), lomprog(1M), lom(1M), tsdog(1M), and tsstate(1M) and for tsunlock(1M), tsctl(1M), tsmonitor(1M), and lomlited(1M).

Changing the First Character of the LOM Escape Sequence

To change the first character of the LOM escape sequence, use the lomctl utility. type:

# lomctl escape=X

where X is the character you want to use instead of "#."

Front and Back Panel LEDs

The Netra contains two front panel LEDs:

The Sun Netra t1 contains four back panel LEDs:

Fans Monitored by the LOM Device

Event reports about the fans inside the system include the number of the fan to which they relate.
Fans 1 and 2 cool the motherboard and Fan 3 cools the PCI bay. The power supply fan is monitored as part of the power supply unit (PSU), therefore, if this fan fails, the LOM reports it as a PSU failure.

To check the status of the fans:


Step 1 Type the LOM escape sequence (by default this is #.) to get to the lom prompt.

Step 2 Type the following at the lom prompt:

environment


Maintaining the System

If you ever need to replace an entire Netra t1 system, the section also tells you how to capture and retain the configuration information for one system and transfer it to another. This configuration information is stored in a device on the motherboard called the Host ID chip.

The section contains the following sections:

Re-using the Data in the Host ID Chip

If you must replace an entire Sun Netra t 100 or Sun Netra t 105, you can re-use the old system host name and MAC address in the new system. The host name and MAC address are stored on the motherboard, in a removable component called the Host ID chip. To transfer them to a new system, consult the Sun Netra t1 System User and Administration Guide.

Replacing the Lithium Battery

If you must replace the lithium battery on the motherboard, you will see the following message on your console when you boot the system:

Warning -- Real-Time-Clock (and NVRAM) battery is low

If you see this message, order a new lithium battery (part number: 100-5893) and consult the
Sun Netra t1 System User and Administration Guide to replace the battery.


Caution There is a danger of explosion if the lithium battery is incorrectly replaced. Replace it only with a battery of the same type as the used battery (part number: 100-5893) or with a battery of an equivalent type that has been recommended by Sun Microsystems, inc. To replace the battery, follow the instructions supplied with the new battery. Dispose of the used battery according to the manufacturer instructions.

Troubleshooting

This section lists some problems that you might encounter setting up or using the Sun Netra t1 system and tells you how to solve them.


Note If you are not using the factory-configured system software (for example, because you have installed a different operating system over the pre-installed software), make sure that you apply the patches listed in the patches section.

If you cannot find a solution to your problem in this section, contact your local Sun Enterprise Services representative.

The section contains information to help you when you:

Cannot Set Up a Console Connection to the Sun Netra t1

The Sun Netra t 100 and Sun Netra t 105 serial port pinouts are listed on page 15. Check that they are correct for the device (that is, the terminal or terminal server) that you are connecting to the
Sun Netra t 100 and Sun Netra t 105.

Note that the pinouts in the Sun Netra t 100 and Sun Netra t 105 serial ports correspond with the pinouts in the RJ-45 ports on the Asynchronous Serial Interface Breakout Cable supplied by Cisco for use with the Cisco L2511 Terminal Server. For Terminal Servers from other manufacturers, you may need to make your own cross-over (null-modem) cable

Cannot Boot from the Internal CD-ROM drive

If you do not have patch 108673-04 applied and you have Sun Solaris installed, then apply the patch and try booting again from the CD-ROM drive.

If you do not have patch 108673-04 applied but you have no operating system installed, do the following:


Step 1 At the ok prompt, type:

ok setenv auto-boot? false

Step 2 Next, type:

ok reset-all

Step 3 If you had the auto-boot? environment variable set to TRUE originally, return it to TRUE by typing:

ok setenv auto-boot? true

Step 4 When the system has finished performing the reset, wait for 30 seconds, then try booting again from the CD-ROM drive.

Step 5 If this was not successful, check that the CD-ROM drive and cables are properly seated.


Cannot Plug the Network Cable into a Port on a PCI Card

Make sure that the PCI card is seated horizontally in its connector. It must not sit at an angle.

Cannot Return to Sun Solaris After a Break to the OBP Prompt

If you experience this problem, return to Sun Solaris by rebooting the system. Then apply patch 108620-04.

Cannot Get to the lom Prompt Using the (#.) Escape Sequence

Check whether the first character of the "#." escape sequence has been changed (this is a user-configurable value). To check the current value, type the following from the Sun Solaris prompt:

# lominfo info

The information that this command displays includes the serial escape character. If this is not "#," then try using whatever character is currently specified.

If you still cannot get to the lom> prompt, make sure that you have packages SUNWlomu, SUNWlomr, and SUNWlomm loaded. If you have installed new operating system software over the software that was pre-installed on your Sun Netra t 100 and Sun Netra t 105 system, you must re-install the LOM software from an orderable CD (part number: X6972A).

Cannot Install Sun Solaris from the Sun Solaris 2.6 hw3 CD

You need the supplementary Sun Solaris Operating Environment Installation CD (part number: 704-6914-10) to install Sun Solaris 2.6 onto the Sun Netra t 100 and Sun Netra t 105. Note that this CD is supplied with the hardware.
