General maintenance and best practices
Hitachi Unified Storage Hardware Service Guide
Periodic maintenance procedures
describes periodic maintenance tasks for the storage system.
Inspect and clean the storage system regularly, as dictated by your
environment.
Inspecting the fans
A Fan Unit is only installed in the CBL. The fan for the CBXSS/CBXSL/CBSS/
CBSL is built into the Power Unit. Inspect the fans when the storage system
power is turned on.
Cleaning the storage system
To clean the storage system, check whether the air vents are clogged by
dust. If they are clogged, remove the dust with a vacuum cleaner or wipe
the dust with a dry cloth.
Keep the internal and external sides of the front bezel (you may need to
remove the front bezel as described in
Removing and replacing the front
) and keep the rear panel clean. Otherwise, the
ventilation passing through the storage system can be affected, causing the
storage system temperature to rise and result in a failure or possibly a fire.
Do not move the storage system during cleaning.
