A.1 Troubleshooting
The table below lists some errors that may occur during the operation
of the DVS system and details how to resolve them. If you experience
trouble that cannot be resolved with the solutions described here or in
chapter “Maintenance” on page 5-1, please contact your local vendor
or DVS directly.
Error Cause Solution
Accesses to the main
storage are slow.
AND/OR
Drops occurred dur-
ing playout/capture.
The data storage is
too full. It is recommended to use only 85%
of the overall hard disk capacity to
ensure real-time capability. If the
storage is too full, delete some of
your data.
Configurations of the
system have been al-
tered. Contact the DVS service depart-
ment.
One or more hard
disks of the hard disk
array are worn. Try to identify the worn disk and re-
place it as described in section “Hard
Disk Maintenance” 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.
An alarm is sounded
and the alarm LED is
lit. The alarm can be
switched mute with
the mute button. One of the power
supply units has been
disconnected from
power during opera-
tion. Check the LEDs of the power supply
units. If one is extinguished, this unit
may be disconnected from power.
Examine the power cord of the unit.
See to it that it is in good technical
order, correctly plugged in at both
ends and that the mains current is
operating properly.
One of the power
supply units has
failed. Check the LEDs of the power supply
units. If one is extinguished and you
can rule out the above mentioned
cause, a power supply unit has
failed. Replace the broken unit as de-
scribed in section “Power Supply
Maintenance” on page 5-10.
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
“Fan Maintenance” on page 5-8). If
necessary replace the broken mod-
ule as described in the same section.
