Figure 2-1 LEDs on the PA-T3 Serial Port Adapter—Partial Front View
The PA-2T3 has one status LED and six uplink port status LEDs (RCLK, FERF, OOF, AIS, RL, and
LL) for each serial PA-T3 port. (See Figure 2-2.)
Figure 2-2 LEDs on the PA-2T3 Serial Port Adapter—Partial Front View
Table 2-2 describes the PA-T3’s LEDs.
After system initialization, the Enabled LED goes on, indicating that the port adapter has been
enabled for operation.
The following conditions must be met before the PA-T3 serial port adapter is enabled:
• The port adapter contains a valid microcode version that has been downloaded successfully.
• The port adapter is correctly connected to the VIP2 or Catalyst RSM/VIP2 (Cisco 7000 series
and Cisco 7500 series,or Catalyst 5000 series switches) and the midplane and is receiving power
in the Cisco router.
• The bus recognizes the port adapter.
If any of these conditions is not met or if the initialization fails for other reasons, the enabled LED
does not go on.
