Here’s how to connect the network and power.
You have two options for power and network
connections, normal AC power (
A) and
Power over Ethernet (PoE) (
B). Your system
administrator will let you know which one to use.
(A) AC power (optional)
To connect the AC power:
• Connect the DC plug on the power adapter to
the DC5V port on the phone, and plug in the
other end of the power adapter to the mains.
• Connect your included Ethernet cable
between the internet port on the phone and
your switch/hub device port.
(B) Power over Ethernet
You can power the T48 using the included
Ethernet cable from a PoE-compliant switch
or hub.
To connect PoE:
• Connect the Ethernet cable between the
internet port on the phone and an available
port on the in-line power switch/hub.
• If an in-line power switch/hub is provided,
you don’t need to connect the phone to the
power adapter. Make sure the switch/hub is
PoE-compliant. The phone can also share
the network with another network device
such as a PC. This is an optional connection.
Important: Do not unplug or remove power
to the phone while it's updating its firmware
and configurations.
