If you were using software pack-
ages subject to licensing (e.g.
the internal voice mail program
OpenVoice) prior to exchanging
the backplane, this software
needs to be reactivated using
new activation keys. Contact
your dealer or DeTeWe distribu-
tor.

using the backplane serial
number. You will be required to
state this serial number. You can
determine the serial number in

Uninterruptible Power Supply

If you are using uninterruptible
power supplies (UPS), you must pro-
vide a separate UPS either for the
power supply of each frame (cas-
caded PBXs, see PBX Cascading start-
ing on page 98) or for the power
supply of both frames. If one UPS is
used for both frames, it must be
earthed separately.
The total leakage current must not
exceed 3.5 mA per mains socket. Use
the leakage current specified by the
UPS manufacturer as a reference.

The backplane serial number is
also used to encode the PARK of
a DECT system. If you are using a
DECT system with the
OpenCom 510, you will need to
re-enter the PARK.
11. You can determine the new
PARK in the System Info: Ver-
sions menu in the Configurator.
An MPS+1-AC power supply unit has
a leakage current of < 0.5 mA.
A 900-watt UPS is entirely sufficient
to power the OpenCom 510 (this
also applies to cascaded systems).
