A fan has failed. Check the LEDs of the power supply
units. If all are green, shut down the
system (see section “Shutting Down
the System” on page 4-2) and check
whether a fan has failed (see section
“Removal of the Faceplate” on
page 5-13). If necessary replace the
broken module as described in the
same section.
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
within the operation
items is off (some-
times while the LED
disk error can be lit
up in red).

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.

fective.
Replace the defective disk as ex-
plained in section “Hard Disk Main-
tenance” on page 5-2.
The RAID controller is

If you can rule out the above men-
tioned causes, a RAID controller may
be defective. Please contact the DVS
