Monitoring and Maintaining the Active and Standby RSPs

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:

Command	Purpose
Router# show boot var	Displays the environmental variable settings and configuration register
	settings for the active and the standby RSPs.
Router# show flash all	Shows a list of Flash devices currently supported on the router.
Router# show version	Displays the software version running on the active and the standby
	RSPs.

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

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.
