Power Failure

As a precaution in the event of a power failure, unplug the
switch. When the power supply is restored, plug the switch
back in.

Redundant Power Supply

The DES-3326SR can be equipped with a redundant power
supply - the D-Link DPS-200 - to ensure continuation of
service in a failure of the main power unit. An integrated
detection circuit continuously monitors the internal power
supply. In the event of a power interruption, the redundant
power supply is immediately triggered so that the DES-3326SR
and connected devices can continue providing service.
The redundant power supply may be purchased with and
included in the original system installation, or may be added to
an existing system at a later time.
