A phone does not power up.
Phones receive power in one of two ways:
• Power over Ethernet (PoE) from the Services Router—Verify that:
-
No hubs or switches are between the Services Router and the phone because
they will not provide PoE.
-
Cat5 or better wiring is used between the phone and Services Router.
-
The RJ-45 is plugged into the phone's 10/100SW port.
-
If the phone is plugged-in to a wall jack, unplug and connect the phone directly
to the Services Router in order to eliminate the wiring plant as a variable.
-
Try another phone in order to eliminate the first phone. If the new phone powers
up, RMA the first phone. Otherwise, RMA the Services Router.
-
Use an external power supply (pwr-cube-3) to eliminate the Services Router as a
variable. If the phone powers up with an external power supply, RMA the phone
due to faulty PoE.
• From an external power supply:
-
Ensure that the external power supply is plugged into a powered outlet.
-
Ensure that the external power supply's output plug is fully inserted into the
phone.
-
Try another external power supply from a working phone. If the phone powers
up, RMA the external power supply.
-
Connect the phone directly to the Services Router using a Cat5 or better cable to
the 10/100SW port on the phone.
The phone screens on my phones alternate between showing a question mark and a
handshake icon.
This means that the handshake process is still taking place. The handshake process can
be protracted due to high packet loss on the Internet connection. Simply wait; the system
