Power Options for IP Telephones

Avaya supports the IEEE 802.3af, standard for Power over Ethernet (PoE) on its range of IP telephones. With Power over Ethernet, both power and data are carried over one CAT 5 Ethernet cable. Deploying IP telephones utilizing Power over Ethernet eliminates the need for local power supplies, AC adapters and cables, and allows power to be provided from the wiring closet/switch room where it can be easily connected to a UPS system.

There are several power options, in addition to IEEE Power over Ethernet, available to customers to power their Avaya IP telephones.

Avaya Individual Power Supply for 4600 and 5600 phones
Avaya provides individual power supplies that can be used to power each IP phone which provides a single 48 volt output. The power supply can operate globally within a wide range of Alternating Current (AC) input voltages: 90 - 264 Volts Alternating Current (VAC), 47-63 Hz. This power supply has a green indicator (LED) that shows the unit has power to the PHONE socket on pins 7&8 of the CAT5 cable. This item is available in two different versions, with and without an internal battery for uninterrupted power to the phone.
Avaya individual Power Supply for 1600 Series phones
The 1600 Series phones have a special power connecter to allow the connection of a cost efficient power supply. These power supplies come in several versions for different countries and voltages.
Avaya Power over Ethernet adapter for the 1603 phone
The 1603 phone does not support Power over Ethernet natively. A small adapter is needed. The adapter will fit completely in the stand of the phone, offering a cost efficient option of either using a power supply or a PoE adapter.

For 1600 Series phones, a separate line of cost efficient power supplies is available in different regional versions.

 

Avaya Mid-Span Power Distribution Units

These power devices are designed for IP-telephony and provide power over Ethernet (PoE) for up to 24 IP telephones or wireless LAN (WLAN) access points in one unit. The Mid Span Power units are designed to mount in a 19-inch rack with the data equipment or they can be stacked up to four units high using the optional rubber feet. The mid-span is 1U in height (1.75 inches) and has up to twenty-four RJ45 sockets on the bottom row and twenty-four data and power output RJ45 sockets on the top row. The units provide a maximum of 200 Watts or a peak of 16.8 watts per port. Data is unaffected by power delivery, if the device does not require power. The mid-span power units are also referred to as PDU (Powered Data Unit) devices. Power over the LAN will simplify the installation and support of IP telephones for our customers and are available in 3 sizes; 6, 12 or 24 ports with optional SNMP management capability.
