Description
To access the controller CRUs,
battery, storage server fan, and
indicator lights, remove the DS4400
Storage Server bezel.
The DS4400 Storage Server usually
runs continuously. However, you might
need to turn off the power to move the
DS4400 Storage Server or to perform
maintenance procedures.
Run the storage-management
software continuously. This software
checks the storage subsystem for
failures and displays messages
indicating the types of failures and the
recovery procedures.
Component failures are indicated by
lights on the front and back of the
DS4400 Storage Server and are
monitored by the
storage-management software.
Note: The indicator lights identify
problems with the DS4400 Storage
Server components, but you might
need more information to thoroughly
diagnose and repair the unit.
Therefore, it is important to use the
storage-management software to
continuously monitor the status of the
DS4400 Storage Server.
When the DS4400 Storage Server
shuts down because of a power
supply overtemperature condition,
take special care restarting it.
Periodically check the battery service
date information. Replace the battery
whenever it fails to hold a charge or
every three years.
Note: Using the DS4400 Storage
Server in a hot environment (above
35° C or 95° F), lowers the battery life
expectancy. Environmental conditions
that are not in the specified range is
not supported.
You might need to move the DS4400
Storage Server to a new location or
remove the chassis from its rack
cabinet.
