●
Powered Device (PD) is ready to accept power from either set of pairs:
- Spare Pairs (pins 4/5 and 7/8)
- Signal/Data Pairs (pins 1/2 and 3/6)
●
The method of signature detection is the “Resistor” concept.
●
Mid-Span supplies power on the Spare Pairs (pins 4/5 and 7/8).
●
End-Span supplies power on either the Signal/Data Pairs (pins 1/2 and 3/6), or the Spare
Pairs (pins 4/5 and 7/8).
●
The power detection and the power feed operate on the same set of pairs.
For more information on the IEEE Draft 802.3af standard (technically known as “DTE Power
through MDI Task Force”), see:

Local power
Local power is the power that is supplied at the immediate location of the telephone. Local
power requires a 120/240 VAC outlet that is located within 6 feet of the telephone. Power is
provided to the IP Telephone through a power supply with either a CAT 5 LAN cable or a barrel
connector or a special split cord. Each power supply has a different power range in which it can
operate.
Configuring the IP Telephones for power
The Avaya 4600 Series IP Telephones are comprised of the following models:
●
4602 IP Telephone (no barrel connector, one RJ45 jack, no switch, no hub)
●
4606 IP Telephone (barrel connector, two RJ45 jacks, built-in hub)
●
4612 IP Telephone (barrel connector, two RJ45 jacks, built-in hub)
●
4620 IP Telephone (no barrel connector, two RJ45 jacks, built-in switch)
●
4624 IP Telephone (barrel connector, two RJ45 jacks, built-in hub)
●
4630 IP Telephone/Screenphone (barrel connector, 2 RJ45 jacks, built-in hub)
Model 4630
The 4630 IP Telephone is popularly known as the IP Screenphone. Currently, the IP
Screenphone consumes more power than the IEEE limits, and therefore requires local power.
The IP Screenphone must be powered locally through the barrel connector on the bottom of the
telephone using the power supply that is provided with the unit. When using the 30A Switch with
the IP Screenphone, a special split cord is required.
