Possible Cause
The cable is not
properly connected.
You have connected to
the ISDN interface.
There is no power
(PoE) in the LAN
interface. The reason
may be that there is
not enough power to
supply PoE for the
LAN interface.
If you have Multi-
voice, see the

Troubleshooting guide
Remedy
Connect the cable.
Remove the cable and connect to one
of the LAN connectors instead.
Check that the input voltage is within
the specified range
(10.5 - 32 V DC; 14 A - 5.5 A).
Check that you do not have too many
power-consuming devices connected.
The maximum available output power
on the LAN (PoE) interface is 32 W if
you are using a 12 V supply and 64 W if
you are using a 24 V supply.
If possible, disconnect other
connected devices.
See the following entry in this table:
Multi-voice: Voice call is not put
through.
If the correct password is not found,
you have to reset the password.
Contact your supplier for a reset code.
You must provide the serial number
and IMEI number of the terminal.
Then enter the web interface and reset
the password as described in:
