(See Figure 29-7.) All network modules have an enable (EN) LED. This LED indicates that the module is receiving power from the router chassis. The AIC network module also has a status (STAT) LED, which is a software-controlled bicolor (green and orange) LED. Both the EN and STAT LEDs turn on when the router is powered up, recycled, or power-cycled, or the AIC is hot-swapped. When the AIC starts to boot up, the STAT LED is initially turned off. It turns green when the software has initialized, has passed POST, and has established communication with IOS. The STAT LED turns from green to orange when POST has failed or when the software encounters any other fatal fault in its firmware during normal operation.

AIC Network Module LEDs
This section describes AIC network module LEDs. (See
Figure 29-7
.)
All network modules have an enable (EN) LED. This LED indicates that the module is receiving power
from the router chassis.
The AIC network module also has a status (STAT) LED, which is a software-controlled bicolor (green
and orange) LED. Both the EN and STAT LEDs turn on when the router is powered up, recycled, or
power-cycled, or the AIC is hot-swapped. When the AIC starts to boot up, the STAT LED is initially
turned off. It turns green when the software has initialized, has passed POST, and has established
communication with IOS.
The STAT LED turns from green to orange when POST has failed or when the software encounters any
other fatal fault in its firmware during normal operation.
Table 29-4
defines the state of the card with respect to the states of the LEDs.
