Upgrading Your Enterprise 450 Hardware

This section presents common hardware components that must be upgraded and guidelines for performing the upgrades, including:

Required Tools

You will need the following tools to perform the procedures in these sections:

Safety Precautions


Caution Printed circuit boards and hard disk drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static from your clothes or the work environment can destroy components. Do not touch the components themselves or any metal parts without taking proper antistatic precautions.

Follow these safety precautions when performing upgrades to the E450:


Figure 3-17: Using the Antistatic Wrist Strap


Upgrading Hard Drives

You must have a minimum of one 9-gigabyte hard drive. If you want to perform disk mirroring, two drives are required. Cisco recommends disk mirroring. To upgrade hard drives, follow the procedures in the following sections.


Tips Disk drives must be Sun standard 3.5-inches wide by 1-inch high, UltraSCSI-compatible drives. Each disk should be installed in the lowest-numbered drive slot available. Fill drive bays from the bottom of the disk cage to the top. The SCSI IDs for the disks are hardwired on the disk backplanes. There is no need to set any SCSI ID jumpers on the disk drives themselves. The SCSI target address (SCSI ID) of each disk drive is determined by the slot location where the drive is connected to its UltraSCSI backplane. The backplane also provides the SCSI termination for each drive. Jumpers should not be used on the disk drive itself to select a specific SCSI ID.

Removing the Hard Disk Drive


Caution You must follow antistatic precautions when handling a disk drive. See the "Safety Precautions" section. Attach the wrist strap to the inside bottom of the chassis, just inside the bottom door.

Follow these procedures to remove the hard drive:


Step 1   Power off the system:


Caution Before turning off system power, halt the operating system as described below. Failure to halt the operating system properly can result in loss of disk drive data.


Figure 3-18: Standby Position



Figure 3-19: AC Power Switch


Step 2   Open the bottom door. This door covers the lower part of the system's front panel and is hinged on the left side. Unlock the door, if necessary. Pull firmly on the right side of this door and swing it out and to the left.

Step 3   Locate the disk drive that you need to remove.

Step 4   Slide the latch at the right of the drive handle to the right to release it as shown in Figure 3-20.


Figure 3-20: Removing the Hard Disk Drive


Step 5   Swing open the handle as far as it will go and pull on it to slide the drive out.

Step 6   Place the drive on an antistatic mat.


Installing the Hard Disk Drive


Caution If you are installing this part as an option, you must ensure that it does not make your configuration exceed the system power budget; see your Sun E450 documentation for more information.


Caution You must follow antistatic precautions when handling a disk drive. See the "Safety Precautions" section. Attach the wrist strap to the inside bottom of the chassis, just inside the bottom door.

To install the hard drive:


Step 1   Align the drive with its drive bay opening. If you are installing the drive as a new option, install it in the lowest available slot number. Verify that a disk backplane is installed behind the selected drive bay. Orient the drive so that the handle's hinge is on the left and the handle is open (extended). Slide the handle latch to the right to open the handle. Refer to Figure 3-21.


Figure 3-21: Installing the Hard Disk Drive


Step 2   Fit the drive into the guide rails on each side of the drive bay.

Step 3   Slide the disk drive into the drive bay until the handle contacts the disk cage.

Step 4   Swing the drive handle closed until it latches.

Step 5   Closing the handle engages the drive with its backplane connectors. If the system power is on, the green LED beside the disk slot will light to indicate that the drive is properly inserted.

Step 6   Repeat Step 2 through Step 5 for any other drives that you want to add.

Step 7   Close the bottom door, and lock it if necessary.


Caution Before closing the door, make sure that the keylock is turned counter-clockwise as far as it will go.

Step 8   After installing any new part that plugs into the main logic board or any internal or external storage device, you must perform a reconfiguration boot so that your system is able to recognize the newly installed options:

ok boot -r
This command rebuilds the device trees for the system, incorporating any newly installed options. After a device has been added to a device tree, it can be recognized by the system. After the reconfiguration reboot has successfully completed, the system prompt should be displayed.

Note   The system may take anywhere from 30 seconds to two minutes before video is displayed on the system monitor or the ok prompt appears on an attached terminal. This time depends on the level of power-on self-test diagnostics being performed.


Caution Never move the system when system power is on. Movement can cause catastrophic disk drive failure. Always power off the system before moving it.


Upgrading Processors

You must have a minimum of two 300 MHz processors. Depending on the number and speed of the processors in your host, you might have to replace your processor or add additional processors. Follow these instructions to remove and replace or add processors.


Caution You must use processors of identical speed; you cannot mix processors of different speeds.

Installing 400 MHz Processors

If you want to install 400 MHz processors, you must verify that your motherboard supports this processor. To verify:


Step 1   Locate the part number of your motherboard. It is located in the lower left corner of the board and appears on a yellow stripe on the left side of the 64-bit PCI slots. It is a 13 digit number, the first 7 of which is the part number. Only the motherboard with the part number 501-5270 supports the 400 MHz processor. If you have motherboards labeled 501-2996 or 501-5028, you must replace the motherboard.

Step 2   If you have the correct motherboard, you must set jumper J2701(n) to pins 2-3.

Step 3   You must also update the firmware. See the instructions that came with your 400 MHz processor for more information.


Removing a CPU Module


Caution CPU modules are delicate. Be sure to take appropriate precautions to avoid damaging them through electrostatic discharge. For more information, see the "Safety Precautions" section.

To remove the CPU module:


Step 1   Power off the system. See the "Removing the Hard Disk Drive" section.

Step 2   Remove the left side panel:


Note   Removing either of the side panels activates the system power interlock switches. This safety mechanism prevents DC voltages from reaching any internal component when a side panel is removed and the AC power switch is left on. Do not remove a side panel while the system is operating or the system will power off abruptly.


Figure 3-22: Loosening the Captive Screws


.


Figure 3-23: Removing the Panel


Step 3   Locate on the main logic board the CPU module that you want to remove.

Step 4   Lift the ejection levers away from the CPU module to release it from the CPU cage. The ejection levers are located on each side of the CPU module. Using both thumbs, push the levers away from the CPU module.

Step 5   Pull evenly on the corners of the CPU module and slide it all the way out of the CPU cage as shown in Figure 3-24.

Step 7   Replace the left side panel.

Step 8   Initiate a reconfiguration reboot. See the "Installing a Hard Disk Drive" section.


Upgrading Memory

You must have at least 1 gigabyte of memory. If you do not have enough memory, you must add additional dual inline memory modules (DIMMs).

Removing Memory Modules


Caution Dual inline memory modules (DIMMs) are made of electronic components that are extremely sensitive to static electricity. Static from your clothes or work environment can destroy the modules. Do not remove any DIMM from its antistatic packaging until you are ready to install it on the main logic board. Handle the modules only by their edges. Do not touch the components or any metal parts. Always wear a grounding strap when you handle the modules. For more information, see the "Safety Precautions" section.

To remove memory modules:


Step 1   Power off the system. See the "Removing the Hard Disk Drive" section.

Step 2   Remove the left side panel.

Step 3   Remove the CPU Fan Tray Assembly:


Figure 3-26: Removing the CPU Fan Tray Assembly


Step 4   Locate on the main logic board the memory module that you want to remove. The sockets are arranged in four banks, as shown in Figure 27.


Figure 27: Memory Banks


Step 5   Push the ejection lever away from the memory module to eject it from the socket. The lever is to the right of the sockets. There is one lever for each pair of sockets as shown in Figure 3-28.

Step 6   Grasp both corners of the memory module and pull it out of the socket. Place the memory module on an antistatic mat.


Installing Memory Modules


Caution If you are installing this part as an option, you must ensure that it does not make your configuration exceed the system power budget; see your Sun Enterprise 450 documentation for more information.


Caution Dual inline memory modules (DIMMs) are made of electronic components that are extremely sensitive to static electricity. Static from your clothes or work environment can destroy the modules. Do not remove any DIMM from its antistatic packaging until you are ready to install it on the main logic board. Handle the modules only by their edges. Do not touch the components or any metal parts. Always wear a grounding strap when you handle the modules. For more information, see the "Safety Precautions" section.


Step 1   Ensure the system is still powered off.

Step 2   Remove the new memory module from its antistatic packaging.

Step 3   Locate the socket into which you will install the module. The sockets are arranged in four banks, from top to bottom as previously shown in Figure 27. These bank locations are labeled on the top of the chassis, near the main logic board rear panel.

If you are installing additional memory modules, you must fill the banks in the following order: A, B, C, D.


Note   Note - Each bank used must contain four modules of equal capacity (for example, four 32-megabyte memory modules, four 64-megabyte modules) to function properly. Do not mix capacities in any bank.

Step 4   Align the memory module with its socket so that the small notch on the corner of the module is on the same side as the lever as shown in Figure 3-29.


Figure 3-29: Installing the Memory Module


.

Step 5   Hold the bottom edge of the module parallel to its socket. Carefully align the module so that each of its gold edge contacts is centered on a socket pin.

Step 6   Push firmly and evenly on both ends of the memory module until the bottom edge is firmly seated in the socket. Ensure that all contacts engage at the same time. Do not rock the module into place.

Where to Go Next

This completes upgrading your hardware. If you are installing Cisco SLTs to terminate signaling, proceed to "Installing and Configuring the Cisco SLT." If you are not using Cisco SLTs, proceed to "Installing the Sun Solaris 2.6 Operating System."

Verifying The Hardware Installation

After installing new hardware components, you can run a diagnostic program to ensure the system recognizes your components.

To run the diagnostic program:


Step 1   Start at the ok prompt and enter:

setenv auto-boot? false
setenv diag-switch? true
 

This disables automatic booting and runs a diagnostic program.

Step 2   Unplug the network Ethernet cable from the machine.

Details about the system components, including hard drives, memory, and processors, appear on the screen. If you do not see the components you recently installed, you must perform troubleshooting steps to determine the problem. Contact the Cisco TAC for assistance in troubleshooting. See the "Obtaining Technical Assistance" section for more information.

Step 3   The machine eventually stops trying to boot from the network and returns to the ok prompt. Enter the following commands:

setenv auto-boot? true
setenv diag-switch? false
 

Step 4   Reboot the machine.
