Notes
– It is also possible to operate the communication server with the exter-
nal power supply unit APS2 only In this case redundancy operation is
of course no longer possible.
– To ensure that its operation is maintained even in the event of a mains
outage, an external uninterruptible power supply (UPS) must be used.

and for connecting the power supplies, see "Powering the communica-
tion server", page 103.
