service representative. Alarm messages are useful information for
maintenance.

a UPS, refer to the manual that comes with the UPS or the manual for the application that controls
the UPS.

Sleep Switch
The SLEEP mode switch on the front of the server is used for saving power.
If the SLEEP mode switch is pressed, then the server enters into the sleep state (the
Power/Sleep LED blinks). In the power saving mode, the memory data and the states of
the jobs are kept unchanged. In addition, the server in the power saving mode can accept
accesses to hard disks from other machines on the network and perform other network
jobs.
NOTE:
Sleep mode requires an operating system that supports its function.
