Troubleshooting
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 5-14). 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 am-
bient temperature at the front of the
system does not exceed the operat-
ing temperature specified in section
“Technical Data” on page A-4. If the
temperature is within the range,
check the ventilation holes of the sys-
tem and free them from all obstruc-
tions (e.g. dust). In case the problem
persists, contact the R&S DVS ser-
vice 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).
OR
At start-up the system
is not able to initialize
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 Mainte-
nance” on page 5-2.
The RAID controller is
defective.
If you can rule out the above men-
tioned causes, a RAID controller may
be defective. Please contact the R&S
DVS service department.
