LocalDirector Hardware

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

• LocalDirector Hardware Platforms

• Supported Interfaces

LocalDirector Hardware Platforms

LocalDirector introduced the 430 and 416 hardware platforms in Version 2.2.1. Support for the previous LocalDirector hardware platforms (the 410, 415, and 420, fully described in Version 2.1 of this guide) continues. Table 2-1 shows the features offered by the 416 and 430 platforms.

LocalDirector 430 (LDIR-430)

LocalDirector 430 includes:

• 384 MB of RAM

• 2 MB of Flash memory

• One 4-port 10/100 Ethernet interface card, optional FDDI

• 19-in. rack-mount enclosure

• DB-9 EIA/TIA-323 console interface port

• 3.5-in. diskette drive

The front panel of LocalDirector 430 is shown in Figure 2-1. Note that the diskette 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 the LocalDirector 430 and 416 are shown in Figure 2-2. The power cord receptacle and power switch are located at the back of the units.

LocalDirector 416 (LDIR-416)

LocalDirector 416 includes:

• 32 MB of RAM

• 2 MB of Flash memory

• Three 10/100 Ethernet interface ports

• 19-in. rack-mount enclosure

• DB-9 EIA/TIA-323 console interface port

• 3.5-in. diskette drive

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.

Supported Interfaces

Table 2-2 shows the interfaces that are supported on LocalDirector platforms.

Interface Numbering

Interfaces on LocalDirector models are numbered left to right, top to bottom. Figure 2-5 shows the interface numbering for a LocalDirector 430 with four 4-port Ethernet interface cards installed.

Figure 2-5: Interface Numbering for LocalDirector 430

4-Port Interface Cards

One 4-port Ethernet card is shipped standard with LocalDirector 430. Up to three more
4-port Ethernet cards can be added.

LocalDirector supports two types of 4-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 2-3 describes the types of 4-port Ethernet cards that ship with LocalDirector.

LEDs for Intel Ethernet Cards

Each interface port has two green LEDs. The following describes the two LEDs on the Intel Ethernet 4-port interface cards:

LEDs for RNS Ethernet Cards

Each interface port has two LEDs, one amber and one green. Table 2-4 explains the states of the LEDs on the 4-port interface cards.

• Green---Indicates data transmission activities relative to the amount of traffic

• Flashing amber---Autosensing in progress (even with no configuration and no cable connections)

• Steady amber---Active connection (this is normal operation)

Autonegotiation

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

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 auto-negotiation 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.

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