ACTIVITY
When the system boots, it runs a series of tests for each module installed
in the system, and the LEDs display various configurations. Refer to the
tables in this section to understand normal and abnormal LED activity.
For troubleshooting information, see
The system's modules have two sets of status LEDs. The top set indicates
generic router and module status. The bottom set indicates
module-specific status, such as port status (line modules) or fan status
(SRP module).
The number against the port status LED on a line module corresponds to
the number of the port on the I/O module. Some line modules have more
port status LEDs than the number of ports on the I/O module. In these
cases, only the LEDs for the corresponding ports on the I/O modules are
active.
For example, an OCx/STMx line module can pair with either an OC3-4
or an OC12/STM4 I/O module. Consequently, the line module has four
port status LEDs for OC3/STM1 operation. However, only the top set of
port status LEDs are active during OC12/STM4 operation.
Table 10-2 shows the functions of the module and port status LEDs.
