Connect the cables
Every port on the front of the 1152A1 PDU is configured as a data route-through port for every data wire
(pins 1, 2, 3, and 6).
Use a standard CAT5, CAT6, or CAT6e straight-through Ethernet cable (not supplied), including all
8 wires (4 pairs) as shown in Connecting cables to telephones and other end devices
on page 111.
Figure 31: Connecting telephones and other end devices to the 1152A1 PDU
For Data-In ports connect the Ethernet cable leading from the Ethernet Switch/Hub to the Data port. For
Data & Power Out ports connect the Ethernet cable leading to the telephone or other end device to the
corresponding Data & Power port.
NOTE:
Be certain to connect correspondingly numbered Data and Data & Power ports.
Connecting cables to telephones and other end devices
Due to an 1152A1 PDU’s line-sensing capabilities, this PDU only powers end devices designed to
receive power from the LAN. When connected to an 1152A1 PDU, such a device (termed Power over
LAN Enabled) receives both its power and data via the Ethernet cable.
To safeguard devices that are not enabled, an 1152A1 PDU can detect these devices and send them data
via the Ethernet cable, without transmitting power.
An end device that cannot receive power directly may receive its power and data through an external
splitter. The splitter separates the power and data before connecting to the end device (see Connecting an
IP telephone with an external splitter on page 112).
