Chapter 2 — Installing the Power Bridge
12 MobileLAN power User’s Guide
The Power Bridge detects devices that are not enabled, and the
Power Bridge will not send power to those devices. Data continue
to flow via the Category 5 (or higher) cabling regardless of the
status of the end device.
End devices that have not been 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 the next illustration.

Connecting end devices to the power bridge. Since the 2102 is not Power over
Ethernet Enabled, it must be connected to a splitter before it can be connected to
the Power Bridge.
Before connecting end devices to the Power Bridge, determine if
the end device is Power over Ethernet Enabled or not.
Note: If the end device is not Power over Ethernet
Enabled, the end device may be safely connected;
however, the port supplies no power, and it functions as a
normal Ethernet data port.
In addition, be sure that
•
the end device either requires an external splitter or requires only
a single RJ-45 connection. If an external splitter is needed, be
sure to use a splitter with the correct connector and polarity.
•
the end device’s power requirements are consistent with the
Power Bridge voltage and power ratings. See Appendix B for
voltage and power ratings.
