Installing and Wiring Telephone Power Supplies
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
Connecting an IP telephone with an external splitter
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
