This chapter describes the GigE interface card and contains the following sections:
The GigE interface card is intended for use with high-traffic Internet sites. When installed in the Cisco LocalDirector 430, the GigE interface card increases data throughput to nearly 1000 Mbps. You can install up to four GigE interface cards in a single Cisco LocalDirector 430.
The GigE has one row of three status LEDs. The fourth LED is not used. (See Figure 1-1.)
Table 1-1 lists LED colors and meanings.
| 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. |
The LocalDirector GigE 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 1-2.

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. |
