The following table can be used to provide an quick initial calculation for the UPS rating
required. Allowance should be made for future expansion by including a margin in the UPS
power rating.

power rating.
Note 1: As PoE technology is used, this
calculation only has to take into
account directly powered equipment
(switches, midspan units)

Note 2. the backup time required
(between _ hour and 8 hours, typically
between 2 and 4 hours) is also very

For this example, a Pulsar EXtreme 2KVA/1330W would provide the power required for a typical backup time. If a longer
backup time is required, a Pulsar Extreme 3KVA/2000W with 2 “XLA” battery modules would provide equipment with a
backup time of more than 2 hours.
