IP System Telephone Ports
IP system telephones have additional ports not included with the standard
system telephones. Above the display on the back of the device there are two
RJ45 jacks for connecting the data line(s). These ports are labelled
LAN
and
PC
. Depending on how your workstation is equipped technically, there are
two options for connecting the IP system telephone. Your system adminis-
trator will connect the telephone for you. If for whatever reason the lines get
disconnected at some point, follow the steps below to reconnect the tele-
phone yourself.
Option 1: Your Workplace Computer has a Network Port Available.
Insert the network cable into the telephone’s
LAN
port and the other end of
the cable into the available network port.
Option 2: Your Workplace Computer has just One Network Port Available
which is Used by Both Telephone and PC.
The telephone can be looped into the existing network connection via its
LAN
and
PC
jacks. To connect the telephone, use a network cable to connect the
telephone to the PC, one end of which is inserted into the
PC
port of the tele-
phone. A second network cable is inserted into the
LAN
port of the telephone,
the other end of which goes into the network port.
The power supply of the telephone and the connected key extensions is
provided by the network feed (“Power over Ethernet”). If your company
network does not supply Power over Ethernet, the telephone will require a
separate power supply via an additional AC adapter plug (product code
90035810; product name “Forum 500 power for keypad & FIP 525/535”).
The AC adapter plug is plugged into the port on the base of the telephone.
This symbol
identifies this port. If there are one or more key extensions
connected to this telephone, the AC adapter plug is not plugged into the port
on the base of the telephone but into the outside key extension (insert it into
the port with the
symbol) and provides power to the entire device.
Please note:
Never operate an IP system telephone with PoE and
AC adapter plug simultaneously!

need help with anything in this regard, please contact your system adminis-
trator.
