Power over LAN Hub
- Power In-Line Patch Panel
Overview
There are two methods available from Nortel Networks. Either integrated via Baystack LAN Switching
(refer to Baystack 460) or Power over LAN Hub (POL).
The POL Hub is part of the Nortel Networks Succession portfolio of Internet Telephony Solutions. It provides
power to i2004/i2002 Internet telephones using existing LAN cable infrastructure. It delivers power over the
unused pairs of standard category 5 LAN cables. The POL Hub features a sophisticated load auto-sensing
algorithm that provides power to devices only as required. This monitoring capability ensures continuous
proper operation of i2004/i2002 Internet Telephones.
The POL Hub solution fits as standard equipment in the wiring closet and eliminates the need to connect
each telephone to an AC power outlet. The POL Hub can be operated with any commercially available UPS.
This solution consists of a centrally located power supply that is installed in the wiring closet. It supports
24 ports and connects as standard equipment into the wiring closet.
The IEEE 802.3 af standard

is emerging at present, both solutions above the Baystack and POL Hub are
compliant with this standard.

i200x will support this standard from mid year 03.
Customer Profile
The Power over LAN Hub forms the basis of a power
system that brings PBX reliability to Voice over IP
while maintaining the plug and play installation
typical of data networks. Power over the LAN and
reliable system backup are additional options
available to maximise system reliability throughout
the network and meet customer expectations for
telephony availability and reliability.
