Uninterruptible power supply (UPS)

The use of an external uninterruptible power supply (UPS) guarantees operation
even in the event of a mains outage.
The UPS battery capacity is rated according to the communication server's primary
power requirements and the required bridging time. The table below shows the
maximum power requirements of the communication server in its maximum con-
figuration and maximum traffic volume.

The battery capacity required [Ah] can be calculated using the battery voltage and
the maximum bridging time. It is important to note that the battery must never be
allowed to become completely discharged and that in typical conditions only ap-
prox. 60% of the maximum power requirements is needed.
Note
The uninterrupted operation of the communication server is ensured if
the UPS takes over the power supply within 20ms of the mains outage.
