LocalDirector Hardware

This chapter describes LocalDirector hardware platforms, including interface cards. This chapter contains the following sections:

LocalDirector Hardware Platforms

LocalDirector introduced the 430 and 416 hardware platforms in Version 2.2.1. Support continues for the previous LocalDirector hardware platforms (the 410, 415, and 420).

LocalDirector 430

LocalDirector 430 includes:

The front panel of LocalDirector 430 is shown in Figure 2-1. Note that the disk drive, interfaces, console port, and failover port are accessed from the front panel.


Figure 2-1: LocalDirector 430 Front Panel


The back panel of both LocalDirector 430 and 416 is shown in Figure 2-2. The power cord receptacle and power switch are located at the back of the units.

LocalDirector 416

LocalDirector 416 includes:

The front panel of LocalDirector 416 is shown in Figure 2-3.

Rack-Mount Brackets

Rack-mount brackets are optional on LocalDirector 430 and 416. Figure 2-4 shows you how to attach the brackets.

LocalDirector Interface Numbering

Interfaces on LocalDirector are numbered left to right, top to bottom. Figure 2-5 shows the interface numbering for installed interface cards.


Figure 2-5: Interface Numbering for LocalDirector 430


Four-Port Interface Cards

One four-port Ethernet card is shipped with LocalDirector Model 430. Up to three more four-port Ethernet cards can be added in the Model 430.

LocalDirector supports two types of four-port Ethernet cards. To check the type of card you have, use the show interfaces command. The output of the command tells which type of card you have. Table 2-2 describes the types of four-port Ethernet cards that ship with LocalDirector.

LEDs for Intel 10/100 Ethernet Cards

Each interface port has two green LEDs. The two LEDs on the Intel Ethernet 4-port interface cards can appear either as:

LEDs for RNS 10/100 Ethernet Cards

Each interface port has two LEDs, one amber and one green. Use the following LED definitions to understand the states of the 4-port interface cards.


Note   The interface ethernet 0 auto command causes the amber LED to flash continually when the link is not up, and the interface ethernet 0 [10baset|100basetx|100full] command shuts off the amber LED when the link is not up.


Table 2-3: 4-Port Interface LEDs for RNS Ethernet Cards

LED
LED State
Indication

Green

Off

No data transmission.

On

Steady data transmission.

Flashing

Intermittent data transmission.

Amber

Off

Disabled or unused. If the interface is configured with the 10baset, 100basetx, or 100full options, the link is not up yet.

On

The connection is active.

Flashing

Autosensing. If the interface is configured with the auto option, the link is not up yet.


Note   The LED behavior on the RNS 4-port Ethernet interface is different from the behavior of other Cisco products.

Autonegotiation

The 4-port rns23x0 Ethernet card does not accept the auto option with the interface ethernet command, and returns the following error message:

ERROR: this port does not have autonegotiation capability.
 

The ports on the 4-port rns23x0 Ethernet card default to 100BaseTX. The 10baset, 100basetx, and 100full options are available, but the auto option is not.

If the peer port autonegotiates, the 4-port rns23x0 Ethernet interface speed must be set with the 10baset or 100basetx options; setting it to 100full confuses the autonegotiation process on the peer port, resulting in unpredictable behavior.

The LocalDirector 416 single-port Ethernet card and the LocalDirector 430 i82557 Ethernet card perform autonegotiation, but your network interface must support autodetection.


Note   The 4-port interface does not automatically detect full duplex. This can cause a problem if the LocalDirector interface is at half duplex and is connected to a switch on the other end that is trying to connect at full duplex.

FDDI Interfaces

FDDI interface cards are optional on LocalDirector 430, and they cannot be mixed with Ethernet interfaces. FDDI interface cards support SMT 7.3.

An easy way to understand FDDI topology is to disregard the dual-attached interfaces. Treat dual-attached interfaces like single-attached interfaces; then treat FDDI like Ethernet; then the network topology looks like an Ethernet topology. Once the topology is determined, put the dual-attached interfaces back into the mix by keeping in mind that the dual-attached interfaces only provide topology redundancy--if a wire is cut, you have another wire to use as a backup. It does not mean you can attach additional servers because you have extra ports.

When installed in LocalDirector, Port A is on the bottom of the interface, and Port B is on the top as shown in Figure 2-6.


Figure 2-6: LocalDirector FDDI Interfaces


FDDI interface boards for LocalDirector have dual-attached SC connectors as shown in Figure 2-7.


Figure 2-7: LocalDirector FDDI Connectors


Figure 2-8 shows a LocalDirector failover implementation with FDDI interfaces.


Figure 2-8: LocalDirector Failover Implementation with FDDI



Note   The FDDI interfaces on the standby LocalDirector are active in the FDDI sense, but they do not pass load-balanced traffic unless the active LocalDirector fails.

Gigabit Ethernet Interfaces

The Gigabit Ethernet network interface card (also referred to as the GigE card) is used with high-traffic Internet sites. The GigE card increases data throughput to nearly 1000 Mbps when installed in the Cisco LocalDirector 430. You can install up to four GigE network interface cards in a single Cisco LocalDirector 430.

The GigE has one row of three status LEDs. The fourth LED is not used.


Figure 2-9: Gigabit Ethernet Interface Card LEDs


Table 2-4 lists LED colors and meanings.


Table 2-4: GigE Interface Card LEDs
LED Label Color State Meaning

TX

Green

On

Indicates the GigE is sending data.

RX

Green

On

Indicates the GigE is receiving data.

LINK

Green

On

Indicates the GigE is connected to a valid link partner and is receiving link pulses.

Cables and Connectors

The GigE card uses dual-attached SC connectors with 1000BASE-SX multimode fiber-optic cables. The dual-attached SC connector port and dual-attached SC connector are shown in Figure 2-10.


Figure 2-10: LocalDirector GigE Interface Card Connectors



Note   The maximum distance specification for 1000BASE-SX-standard 62.5-micron diameter fiber is 260 meters. The maximum distance specification for 1000BASE-SX-standard 50-micron diameter fiber is 525 meters.

Configuring the GigE Interface Card

To continue your GigE interface card installation, you must configure the gigabit Ethernet port. The instructions that follow apply to all supported platforms.

Configuring the Gigabit Ethernet Port

Configure the port speed and duplex mode to "1000" and "full" using the interface ethernet command arguments:

interface ethernet interface_number 1000full
 

Figure 2-11 shows a typical LocalDirector gigabit ethernet topology:


Figure 2-11: LocalDirector Gigabit Ethernet Implementation




Checking the Gigabit Ethernet Port Configuration

After configuring the new gigabit ethernet port, use the show configuration command to display the status of the new interface or all interfaces. The show configuration output should contain the following text:

interface ethernet 0 1000basesx
interface ethernet 1 1000fullauto
