BladeCenter JS20 Type 8842: Installation and User's Guide
Action
An error has occurred that is not represented
by a light path diagnostics LED. Check the
system event log in the BladeCenter
management module for more information
about the error.
Replace the DIMM indicated by the lit DIMM
failure LED.
Note: Multiple DIMM LEDs do not necessarily
indicate multiple DIMM failures. If more than
one DIMM LED is lit, reseat or replace one
DIMM at a time until error is corrected. Check
the system event log in the BladeCenter
management module for information about the
error.
If the problem remains, have the blade server
serviced.
Attention: To help ensure proper cooling and
system reliability, two microprocessors and two
heat sinks are required on the system board in
the blade server at all times. The
microprocessors and heat sinks on the system
board are not replaceable. Therefore, if a
microprocessor or heat sink becomes
defective, you must replace the system-board
assembly. Contact a service support
representative for assistance.
Have the blade server serviced.
Note: There are two service processor error
LEDs: CR27 (amber) and CR38 (green).
1. Replace the blade server cover, reinsert
the blade server in the BladeCenter unit,
and then restart the server.
2. Check the system event log in the
BladeCenter management module for
