JS12 Type 7998: Problem Determination and Service Guide
Description and Action
Display Character test failed.
Note: Diagnostic will provide this SRN but there is no action to be taken. Do not
perform operator panel test from diagnostics.
Sensor indicates a voltage is outside the normal range. Go to "Performing the
checkout procedure" on page 187.
Sensor indicates an abnormally high internal temperature. Verify that:
1. The room ambient temperature is within the system operating environment.
2. There is unrestricted air flow around the system.
3. All system covers are closed.
4. Verify that all fans in the BladeCenter unit are operating correctly.
Sensor indicates a FRU has failed. Use the failing function codes, use the physical
location code(s) from the diagnostic problem report screen to determine the FRUs.
Sensor indicates a voltage is outside the normal range. Go to "Performing the
checkout procedure" on page 187.
Sensor indicates an abnormally high internal temperature. Verify that:
1. The room ambient temperature is within the system operating environment.
2. There is unrestricted air flow around the system.
3. There are no fan or blower failures in the BladeCenter unit.
If the problem remains, check the management-module event log for possible causes
of overheating.
Sensor indicates a FRU has failed. Go to "Performing the checkout procedure" on
page 187.
Sensor status not available. Go to "Performing the checkout procedure" on page 187.
Sensor status not available. Go to "Performing the checkout procedure" on page 187.
Uncorrectable memory or unsupported memory.
1. Examine the memory modules and determine if they are supported types.
2. If the modules are supported, then reseat the DIMMs.
3. Replace the appropriate memory modules.
Missing or bad memory. If the installed memory matches the reported memory size,
then replace the memory; otherwise, add the missing memory.
Failed memory module. Go to "Performing the checkout procedure" on page 187.
Failed memory module. Go to "Performing the checkout procedure" on page 187.
Memory module has no matched pair. The most probable failure is the memory
module paired with the memory module identified by the location code.
1. Examine the memory modules and determine if they are supported types.
2. If the modules are supported, then reseat the DIMMs.
3. Replace the appropriate memory modules.
Bad L2 cache. Go to "Performing the checkout procedure" on page 187.
Missing L2 cache. Go to "Performing the checkout procedure" on page 187.
CPU internal error. Go to "Performing the checkout procedure" on page 187.
CPU internal cache controller error. Go to "Performing the checkout procedure" on
page 187.
External cache ECC single-bit error. Go to "Performing the checkout procedure" on
page 187.
