1152B Power Distribution Units
The Avaya 1152B Mid-Span Power Distribution Units are Ethernet power supplies that provide
power to up to 48 46xx-series or 96xx IP telephones or wireless LAN (WLAN) access points.
The 1152B PDUs are designed to deliver power in addition to data communication over an
Ethernet network. The 1152B PDUs eliminate the need to connect each Ethernet Data Terminal,
such as an IP Telephone set, to an AC power outlet in addition to the data port. The system also
removes the need for power cables, local AC wall adapters and the use of a dedicated UPS for
each IP telephone. Some models support SNMP remote management via a separate physical
RJ45 input port.
These units are used with a standard 10/100BaseTx Ethernet network infrastructure using
standard TIA/EIA-568 Category 5, 5e, or 6 100-Ohm Unshielded Twisted Pair (UTP) cable. The
1152B meets the current requirements of the IEEE802.3af-2003 standard for resistive detection.
The units are as follows:
The 1152B PDU complies with the Underwriters Laboratories Inc. (UL) standard UL 60950-1,
1
st
Edition.
