Monitoring the Status LEDs

You can determine the redundancy state of line modules and SRP modules by examining their status LEDs. See Table 44 for a description of the LEDs functions. In addition, if you issue the show version command, the state field for the slot that contains the redundant SRP module should be standby.

Table 44: Function of the Online and Redundant LEDs
