example, at a small branch office this may be the same line that is used for faxes/modems/etc. The
handset is also connected to the Power Save Adapter – You must unplug the handset from the IP
telephone and reconnect it to the adapter. This allows the speech path to be redirected to the handset
during network power failure.

LAN Connection

The IP telephone has two RJ-45 connections on the back marked PC and LAN. This allows the IP
telephone and a PC to share one cable run and switch port.
If installing an IP telephone at a location that has a PC connected to the data network, one of the
following methods can be used:
Using a different cable:
Leave the PC connected to the LAN.
Patch a switch port to the new cable run.
Connect a CAT 5 straight-through cable from the wall outlet to the LAN port on the IP telephone.
Sharing the existing cable:
Unplug the cable from the PC Network Interface Card (NIC).
Connect the cable to the LAN port on the IP telephone.
Connect a new straight-through patch lead from the PC NIC to the PC port on the IP telephone.

Powering the IP Telephone

Power can be provided to the IP telephone by one of the following methods:
Local Power
The IP telephone has a connector on the back for external power. This is supplied by an AC
adapter that outputs +27VDC requiring a separate power outlet per IP telephone. Loss of power in
the building will prevent the telephones from functioning.
Only use the NEC supplied power supply.
Power over Ethernet (PoE)
The PoE switch (802.3 AF is only method supported) provides power over the spare pairs. The
switch can be used with other devices than the IP telephones and detects whether or not power is
needed. Using a PoE switch makes it easier to protect the IP telephones from loss of power
(connection of the PoE switch to an UPS).

LLDP

Added support for Link Layer Discover Protocol (LLDP) or IEEE 802.1AB is a vendor neutral Data link
layer protocol used by network devices for advertising their identity, capabilities and interconnections on
the IEEE 802 LAN network. LLDP performs functions similar to several proprietary protocols such as
Cisco Discovery Protocol, Extreme Discovery protocol, Nortel Discovery Protocol (also known as
SONMP) and Microsoft's Link Layer Topology Discover (LLTD). If enabled, the IP terminal takes longer
to boot as it waits for an information packet. If no LLDP information is received within the RX Wait Time,
the terminal continues a normal boot process.
This service supports the Link Layer Discovery Protocol (LLDP) standard and is used to transmit and
receive VLAN information ONLY about neighboring network devices and IP Telephones. The following
are a list of VLAN settings which can be received by the terminal during a LLDP session:
