Procedure
Step 1
Check each power module to make sure that:
• Power module door is fully closed and properly secured by its latch.
• Green Input Power LED is on.
• Green Output Power LED is on.
• Red Fault LED is off.
If the power modules meet the above criteria, then the correct source power is present and within tolerance
and output DC power is present. The power modules are functioning properly.
Step 2
Make sure the fan trays are operating:
• If the fan trays are functioning, then the –54 VDC from the chassis backplane and the cables from the
backplane to the fan trays are functioning properly.
• If one or both fan trays are not functioning, there may be a problem with either the fan trays themselves,
or the –54 VDC power supplied to the fan trays. Eject and reseat the fan trays.
• If a fan tray is still not operating, there could be a problem with the fan tray controller card or cable.
Replace the fan tray.
• Contact your Cisco representative if replacing a fan tray or both fan trays does not fix the problem.
Troubleshooting the Route Processor Subsystem
The router processor subsystem consists of the route processor located on the RSP card. The RSP and the line
cards each have the same onboard CPU serving as the main processor. The Controller Area Network (CAN)
microcontroller processor monitors the environment and controls the onboard DC-to-DC converters.
A minimally configured router must have an RSP/RP installed in RSP slot 0 or RP slot 0 of the card cage to
operate. If the router is equipped with a redundant RSP/RP, the redundant RSP/RP must be installed in RSP
slot 1 or RP slot 1 of the card cage.
