7 Connecting Telephones and Adjunct Systems: Installation and Wiring Telephones and Power Supplies
Connecting cables to telephones and other end devices
The 1152A1 PDU contains line-sensing capabilities that enable it to send power only to end devices
designed to receive power from the LAN. These end devices, termed Power over LAN Enabled,
receive power once they are connected to the 1152A1 PDU.
To safeguard devices that are not enabled, the 1152A1 PDU detects devices that are not enabled so
does not send power. Note that data continues to flow via the Ethernet cable regardless of the status of
the end device.
End devices that are not enabled to receive power directly may receive power and data through an
external splitter. The external splitter separates the power and data prior to connection to the end
device (see Figure

Connection to
Power over LAN Hub
Before connecting telephones or other end devices to the 1152A1 PDU, determine if
• It is Power over LAN Enabled or not.
If not, you may safely connect the telephone; however, the port supplies no power and functions as
a normal Ethernet data port.
• It requires an external splitter or whether it requires only a single RJ45 connection.
If an external splitter is needed, be certain to use a splitter with the correct connector and polarity.
• It's power requirements are consistent with the 1152A1 PDU voltage and power ratings. Refer to
Appendix B in the user's guide that comes with the unit for voltage and power ratings.
To connect telephones and other end devices to the 1152A1 PDU:
1 . Connect an Ethernet cable to the telephone using an external splitter or directly (if the device is
Power over LAN Enabled).
2 . Connect the opposite end of the same cable to the RJ45 wall outlet.
3 . On the front panel of the 1152A1 PDU, monitor the response of the corresponding port LED. If
it lights up GREEN, the unit has identified your telephone as a Power over LAN
