Table 7. Light path diagnostics (continued)
Lit LED Cause Action
Critical error A critical system error has occurred, such as
nonredundancy on the power modules or a
system error in a blade.
Note: You can configure the critical error LED
to be either red or amber through the
management module.
v
Check the error log for messages.
v Look for an error LED on the modules and
blade servers to locate the component:
– If the error LED is on a module, follow
the instructions for the module in this
table.
– If the error LED is on a blade server, see
the documentation that comes with the
blade server.
Management module
System error A critical error has occurred in the
management module.
v If your BladeCenter T unit has only one
management module:
1. Try reseating the management module.
2. Restart the management module.
If the problem remains, replace the
management module.
v If your BladeCenter T unit has two
management modules, the BladeCenter T
unit continues to function using the
redundant module. Replace the failed
management module.
Active Primary management module. If your BladeCenter T has two management
modules, the Active LED indicates which is the
primary management module.
Power module
System error A critical error has occurred in the power
module.
Reseat the power module. If the problem
remains, replace the module.
If your BladeCenter T unit has a redundant
module for this power module, the BladeCenter
T unit continues to function using the
redundant module.
Blower module
System error The blower has failed or is operating too
slowly.
Reseat the blower module. If the problem
remains, replace the blower module as soon
as possible, to regain cooling redundancy.
The BladeCenter T unit continues to function.
The redundant blower module provides cooling
to the BladeCenter T unit and blade servers.
I/O module
System error A critical error has occurred in the I/O module. Reseat the I/O module. If the problem remains,
replace the module.
