Cooling subsystem
(continued)
This shutdown message could also indicate a faulty
component or temperature sensor. Use the show
environment or show environment table command to
display the internal chassis environment.
Make sure that heated exhaust air from other
equipment is not entering the inlet vents, and that there
is sufficient clearance around the chassis to allow
cooling air to flow.

Check to see whether the RP 1 LEDs come on when
system power is turned on.
Processor subsystem
1.
2.
If none of the RP LEDs come on, make sure that both
the fan and the power supply are functioning properly.
3.
If the power supply and fans appear operational but
none of the RP LEDs are on, an improperly connected
RP, SP 2 (or SSP 3 ), or interface processor might have
hung the bus.
4.
If the SP (or SSP) Enabled LED is off but any of the RP
LEDs are on, make sure that the SP (or SSP) is seated
in its slot properly.
5.
Check to see whether the Boot Error LED is on. If the
LED is on, the system software is incapable of starting
up. If you have a spare RP with the system software
ROMs installed, replace the installed RP with the spare
to see whether the system will boot.
6.
Check to see whether the RP CPU Halt LED is on. If it
is, the system has detected a processor hardware
failure. Contact a technical support representative for
more information.
7.
Check to see whether all interface processor Enabled
LEDs are on.
8.
If the Enabled LED on an individual interface
processor is off, make sure that the interface processor
has not pulled away from the backplane.
