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 56: Connecting an IP telephone with an external splitter on page 122).

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.
●Its power requirements are consistent with the 1152A1 PDU voltage and power ratings. See Appendix B in the user’s guide that comes with the unit for voltage and power ratings.
