LAN switching products
The 1152A1 can be collocated with the data equipment or closer to the endpoints. In all cases, IEEE 802.3af capable IP devices must connect directly to this PDU. The PDU cannot power any device if a hub or a switch is between itself and the endpoint because it will not sense the resistive signature needed to authorize the release of power.
Power modes (Avaya IP Telephones)
The Avaya IP Telephone has four different power modes:
●Ethernet spare pairs (4/5 and 7/8)
●Ethernet signaling pairs (1/2 and 3/6)
●Traditional telephony (7/8)
●(4630 model only) External transformer with a barrel connector The 1152A1 power unit powers only through pairs 4/5 (+) and 7/8
Barrel connector through brick transformer
This brick type transformer provides 5 watts of power to the telephone. The Avaya telephone treats this brick as the primary power source, and will not accept power from the Ethernet cable if the barrel is seated into the telephone, with or without the brick attached to AC power.
Ethernet cable through 1152A1 PDU
Adequate power from the 1152A1 is supplied to the generation 2 telephones over the Ethernet cable. Category 5 or better cable is required for Fast Ethernet to function from the IP Telephone.
Power using adapters
Generation 1 telephones can receive power from the 1152A1 through an
Interoperability with Wireless Access Point products
The 1152A1 unit can also power Avaya’s Wireless Access Point systems. The AP1, AP2, or AP3 act as a bridge between the wireless and the wired LAN. This system requires a
