on. If both displays are off, the RP may not be properly seated in the backplane connector. There also might be a problem with the MBus module on the RP, or the system power supply might be off.

•If both displays are on, check the message being displayed. As soon as the DC-DC converter is turned on by the MBus module, the processor on the RP begins the boot process. Status messages are displayed as the boot process continues. Table 4-8 provides a list of messages that can be displayed by the RP alphanumeric LED display. If one of the messages appears frozen, the boot process could be halted. Make a note of the message being displayed. Turn off the system power supply power switches, then turn them back on to reset the system. This starts the boot process again. If the system halts again, the RP could be faulty and might need to be replaced.

–If the power modules and blower module appear operational, but none of the RP LEDs or displays are on, suspect that the RP has not been properly installed or that the +5 VDC output from the alarm card is faulty.

–Turn the power switch to each power module to the OFF position.

–Loosen the two captive screws on the left and right sides of the RP faceplate, and use the ejector levers to eject and reseat the RP. Tighten the captive screws, then power up the system by turning the power module power switches on.

•Is a critical, major, or minor alarm LED on the alarm card on?

–If any of the three alarm card alarm LED pairs is on, a fault has been detected in the system. Check the console for messages indicating the source of the problem.

–There could be a false error indication originating from the RP. You might want to reseat or replace the RP.

Caution The RP reset switch resets the RP and the entire system. To prevent system errors and problems, use it only at the direction of a Cisco-certified service representative.
