Working with the Power Supply Unit
The iPSU needs no scheduled maintenance other than regular battery inspection and replacement. If the
power supply unit is equipped with a backup battery, it continues to provide voice-over-IP services in case of
emergency during a power outage. During a temporary AC power outage, the power source is switched to
the battery without interruption of the voice-over-IP service. When the AC power is restored, the power
source is switched back to the power supply unit. The switchover between the power supply unit and the
battery is automatic and instantaneous.
This section provides instructions to:
•
Replace the battery on
•
Enable the audio alert on
•
Disable the audio alert on
Note:
Reserve the battery charge during a power outage. Do not access the
Internet when the power is running on the battery. Doing so will discharge the
battery at a much faster rate and shorten the voice-over-IP service time.
Note:
You are solely responsible for periodically replacing this battery to
provide uninterruptable voice-over-IP services during a power outage. Your
service provide does not monitor the battery and is not responsible for its
replacement.
