Fe-Tx Port Adapter Leds - Cisco Network Adapter VIP-FE-TX/4E Installation And Configuration Manual

VIP Port Adapter Functions
Table 1 lists the cabling specifications for 100-Mbps Fast Ethernet transmission over UTP and STP
cables. Table 2 summarizes IEEE 802.3u 100BASE-T physical characteristics.

1. EIA/TIA-568 or EIA-TIA-568 TSB-36 compliant.
2. Cisco Systems does not supply Category 5 UTP RJ-45 or 150-ohm STP MII cables. Both are available commercially.
3. AWG = American Wire Gauge. This gauge is specified by the EIA/TIA-568 standard.
4. This is the cable between the MII port on the FE-TX port adapter and the appropriate transceiver.
5. This length is specifically between any two stations on a repeated segment.

FE-TX Port Adapter LEDs

The FE-TX port adapter contains the enabled LED, standard on all port adapters, and a bank of three
status LEDs for the ports. After system initialization, the enabled LED goes on to indicate that the
FE-TX port adapter has been enabled for operation. (The LEDs are shown in Figure 15.) The
following conditions must be met before the enabled LED goes on:
•
•
•
If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED
does not go on.
