Power over Ethernet
With the included or a regular Ethernet cable, the SIP-T48S IP phone can be powered from a PoE-
compliant switch or hub.
To connect the PoE:
1. Connect the Ethernet cable between the Internet port on the phone and an available port on
the in-line power switch/hub.
If 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 (personal computer). It is an optional connection. Important, do not
unplug or remove power to the phone while it is updating firmware and configurations.
