that you have the replacement part available. Removing a
component impacts the airflow and cooling ability of the
device.
To prevent improper cooling and thermal damage, do not
operate the storage enclosure unless all bays are populated
with either a component or a blank.
Do not remove more than one component or blank from the
enclosure at a time. Doing so impacts the airflow and cooling
ability of the device. To avoid possible overheating, insert the
new or replacement component as quickly as possible. If the
internal temperature exceeds acceptable limits, the enclosure
may overheat and automatically shut down or restart.
Parts can be damaged by electrostatic discharge. Use proper
anti-static protection.
Verifying component failure
Before replacing the midplane, use the following methods to
verify component failure:
•
Check the following component status LEDs as identified in
the following tables:
• Hard drives—test with known good hard drives.
• I/O module—test with known good I/O module.
• Fan module—test with known good fan module.
•
Check the host log for errors.
