Troubleshooting The Rp And Sp (Or Ssp); Troubleshooting The Interface Processors - Cisco 7000 Series Hardware Installation And Maintenance Manual

Troubleshooting the Processor Subsystem
incomplete signals to the processor, which will fault the bus and cause the system to hang. Therefore,
first ensure that the RP and SP (or SSP) are installed properly and the system software has initialized
successfully. Then, if necessary, you can troubleshoot individual interface processors.

Troubleshooting the RP and SP (or SSP)

These procedures assume that the RP and router are in the original factory configuration, and that
you have not changed any configuration register settings or made changes to your configuration file.
If you have made such changes, refer to the section "RP and RSP7000 Configurations" in the chapter
"Maintenance" to ensure that all jumpers are set to the factory default. For example, the
configuration register boot field jumper should be set to boot from ROM (0x0001).
If the RP LEDs do not go on as expected, check the following items to help isolate the problem.

4-8 Cisco 7010 Hardware Installation and Maintenance
Do all of the RP LEDs remain off when system power switch is turned on?
— If all RP LEDs stay off, first refer to the sections "Troubleshooting the Power Subsystem"
and "Troubleshooting the Cooling Subsystem" to ensure that both the fan and power supply
are functioning properly.
— If the SP (or SSP) enabled LED is off and any of the RP LEDs are on, the SP (or SSP) may
not be seated in its slot properly. Turn off the system power, loosen the captive installation
screws on the SP (or SSP), and use the ejector levers to eject then reseat the SP (or SSP) in
its slot. Retighten the captive screws and restart the system.
— If the power supply and fans appear operational, but none of the RP LEDs are on, suspect
that an improperly connected RP, SP (or SSP), or interface processor has hung the bus. Turn
the system power switch off and, on each processor module, loosen the captive installation
screws and use the ejector levers to eject and reseat each board. (For a description and
illustration of the ejector levers, refer to the section "Ejector Levers" in the chapter
"Maintenance.") Tighten all captive installation screws, then restart the system.
Is the RP normal LED on?
— If yes, the system software has initialized successfully, and the system is operational.
Is the boot error LED on?
— If yes, the system software is unable to start up. Turn the system power off and then on again.
— If you have a spare RP with the system software ROMs installed, turn off the system power
and replace the installed RP with the spare.
— If after several attempts the boot error LED continues to go on, try to estimate the amount of
time that elapses between power on and when the LED goes on, and contact a service
representative for instructions.
Is the RP CPU halt LED on?
— If yes, the system has detected a processor hardware failure. Contact a service representative
for instructions.
Are all SP (or SSP) and interface processor enabled LEDs on?
— If yes, the system is operational. Proceed to the instructions for configuring the interfaces in
the appropriate software configuration documentation.
