Models 4602 and 4620
The 4602 and the 4620 IP Telephones accept power only through the RJ45 Jack on the
telephone, using either of the following types of power supplies:
Centralized power supply
- Avaya P333T-PWR switch
- 1152A1 Mid-Span Power Distribution Unit
Local power supply
- 1151B1 "Desktop" Power Supply
- 1151B2 "Desktop" Power Supply with Battery Backup
Models 4606, 4612, and 4624
The following section discusses the ways in which local or centralized power can be applied to
the IP 4606, 4612, and 4624 telephones.
Note:
Legacy Power is the least preferred method for powering these telephones.
Note:
Centralized power - For centralized power (PoE), use either an Avaya P333T-PWR switch for
new or Greenfield installations, or an 1152A1 Mid-Span Power Distribution Unit for legacy
systems. The Avaya P333T-PWR switch with Power over LAN capability can use either the data
(pins 1/2 and 3/6) or spare (pins 4/5 and 7/8) pairs for power feeding. A Category 5 Ethernet
cable from an Ethernet LAN Switch carrying DATA is connected to the "data" port of the 1152A1
Mid-Span Power Distribution Unit (PDU). Power is then injected from the "data & power" port
over the spare pair (pins 4/5 and 7/8) on a Category 5 Ethernet cable that is connected to the IP
Telephone.
Local power - The 1151B1 and 1151B2 switching power supplies are the preferred global
solution for local power, and replace the 1151A1 and 1151A2 units, respectively. In addition to
being the preferred solution, the 1151B1 and 1151B2 local power supply units eliminate the
need for any special split cord.
Legacy power - Many existing IP Telephone installations within the United States and Canada
use the IP Phone Aux power supply with a barrel connector. This local power supply is also
known as a "leader" power supply or a wall power supply. Power is supplied through the barrel
connector to a jack on the bottom of the telephone. The 1151A1 or 1151A2 power supply
(commonly referred to as a brick transformer) is an alternative method of powering that requires
one or more special split cords. Many existing IP Telephone installations in international regions
use the 1151A1 or 1151A2 power supply with a required special split cord. If a 30A switch,
three-port switched hub is used with the 1151A1 or the 1151A2 local power supply, two special
cords are required (these cables are included with the 30A switch). The 30A switch is applicable
to the 4624 and 4612 models, but not the 4606 because of its small footprint (the 30A switch
does not fit in the base of 4606 model). The 1145B Bulk Power Supply is an existing
pre-standard solution (that is, the 1145B power supply was developed before the IEEE Draft
IP terminals deployment
