case: a network cable is required for connecting the PC and the
telephone. This cable is inserted into the PC connector on the tel-
ephone. A second network cable goes from the telephone to the
network port; this cable is inserted into the LAN connector on the
telephone.
The power supply of the telephone can take place via the network
line (“Power over Ethernet”). If the company network has no
Power over Ethernet, the telephone requires a separate power
supply via an additional AC adapter (no. D0023-1051-00-75).
Please note: Never operate the Forum IPhone 512 simultane-
ously with PoE and AC adapter!
If you have questions in this regard, desire more information or
require help, contact your system administrator.
