•
If neither the upper nor the lower row is on, but the power modules and the
blower modules are operational, the RP may not be installed properly, or the
+5 VDC output from the chassis backplane is faulty.
–
Make sure that the system is powered on.
–
Initialize the RP by ejecting it from the chassis backplane and then
resetting it.
Caution
The soft reset (NMI) switch is not a mechanism for resetting the RP and reloading
the Cisco IOS image. It is intended for software development use. To prevent
system problems or loss of data, use the soft reset switch only when instructed by
a Cisco certified service representative.
•
If both the upper and the lower displays are operating, check the meaning of
the messages (see
When the DC-to-DC converters are powered-on by the MBus module, the RP
processor begins the boot process and displays various status messages. Some
messages appear briefly; while others appear for several seconds. If the
messages appear to stop at a particular point, the boot process may be halted.
–
Make a note of the message.
–
Turn off power to the router, then turn on the power again to reset the
router and start the boot process. If the router halts again, replace the RP.
