Status Indicator LEDs
After powering on the server or before shutting down the system and powering off the server, check the status
indicator LEDs on the front of the server. For the functions and descriptions of LEDs, see Chapter 1 (5. Names
and Functions of Parts) in User's Guide. If the indicator shows the server abnormality, contact your sales
representative.

Backup
We recommend that you periodically back up the data on hard disk drive. For backup storage devices suitable
for the CPU blade and backup tools, consult with your sales representative.
If a RAID array has been configured on your system, back up the RAID configuration data. We also recommend
that you back up it after a rebuilt process required due to hard disk drive failure. For details, see Chapter 2 (5.3
Utilities in EXPRESSBUILDER).
2.5
Cleaning
Regularly clean the server to keep it in good condition.
Be sure to observe the following precautions to use the server safety. Failure to observe the
