This chapter describes LocalDirector hardware platforms, including interface cards. This chapter contains the following sections:
• LocalDirector Hardware Platforms
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. shows the features offered by the 416 and 430 platforms.

Supported Interfaces
shows the interfaces that are supported on LocalDirector platforms.
Table 2-2 Supported Interfaces by Platform
Interface Numbering
Interfaces on LocalDirector models are numbered left to right, top to bottom. 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 interface command. The output of the command tells which type of card you have. 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:
•Flashing green—Indicates data transmission activities
•Steady green—Active connection (Link Up; this is normal operation)
LEDs for RNS Ethernet Cards
Each interface port has two LEDs, one amber and one green. 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)
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 2-4 4-Port Interface LEDs
Note The LED behavior on the RNS 4-port Ethernet interface is different from other Cisco products. Use to determine if the LED activity indicates normal interface 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:
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 "autosense" to full duplex, causing 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 LocalDirector FDDI Interfaces
FDDI interface boards for LocalDirector have dual-attached SC connectors as shown in .
Figure 2-7 LocalDirector FDDI Connectors
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.
