it is easily accessible.
• Only ever use the supplied power supply unit.

4. 4. 2 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 maxi-
mum power requirements of the communication server in its maximum configuration
and maximum traffic volume.
Tab. 35 Maximum power requirements of the communication server
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 approx. 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.
