Monitoring and Maintaining the Active and Standby RSPs
To display information about the active and the standby RSPs, use any of the following commands
beginning in privileged EXEC configuration mode:
Troubleshooting the Installation
This section contains procedures to follow if your system does not restart as expected. Review the
descriptions that follow so you can anticipate the expected system startup sequence. Then restart the
system and try to isolate the problem by observing the LEDs as the system attempts to boot the software
and initialize the RSPs and each interface processor.
This section includes the following topics:
• Verifying LEDs, page 64
• Verifying System Startup Sequence, page 66
• Troubleshooting a Router That is Failing to Boot, page 68
• Troubleshooting a Failed RSP8, page 68
Verifying LEDs
Following are functional descriptions of the LEDs on the power supplies and processor modules, and the
behavior you should observe at system startup.
System Power LEDs
On the router, the AC (or DC) OK LED is located on each power supply. If this LED does not go on and
stay on, there is most likely a problem with the input power or one of the internal DC lines.
The AC (or DC) OK LED will not go on or will go off if the power supply reaches an out-of-tolerance
temperature or voltage condition. It is unlikely that the power supply will shut down during startup
because of an over-temperature condition; however, it can shut down if it detects an over- or
undervoltage condition during startup. For descriptions of environmental monitoring functions, refer to
the Cisco 7500 Series Installation and Configuration Guide, which is available online, on the
Documentation CD-ROM, or in print.
