The system is over-
heated. If you can rule out the above men-
tioned causes, the alarm must be
due to overheating. See to it that the
ambient temperature at the front of
the system does not exceed the op-
erating temperature specified in sec-
tion “Technical Data” on page A-4. If
the temperature is within the range,
check the ventilation holes of the
system and free them from all ob-
structions (e.g. dust). In case the
problem persists, contact the DVS
service department.
An alarm is sounded
and the alarm LED is
off. The alarm cannot
be switched mute
with the mute button.

At start-up the sys-
tem is not able to ini-
tialize a disk set.
A hard disk or a hard
disk carrier got loose/
jammed (e.g. after
transport) or is not
mounted correctly. Shut down the system as described
in section “Shutting Down the Sys-
tem” on page 4-2. Then perform the
following: Pull all disk carriers partial-
ly out of the chassis and afterwards
install them again. See to it that they
are pulled out and reassembled cor-
rectly as described in section “Re-
placing a Hard Disk” on page 5-4.
After that start the system again.
A hard disk of the
hard disk array is de-
fective. Replace the defective disk as ex-
plained in section “Hard Disk Main-
tenance” on page 5-2.
A RAID controller is
defective. If you can rule out the above men-
tioned causes, a RAID controller may
be defective. Contact the DVS ser-
vice department.
