in a easier to read location. It also shows
Power indicator and a Trouble LED.

Installation Considerations
Wire and Cable Recommendations:
The ER8400C is designed for use with up to 8 coaxial cables. The quality
and condition of which must be considered serviceable cable. It must be free from damage such as cuts, breaks or
cracks to the outer covering and insulated shielding which may compromise the signal conductivity of the cables.

.
Ethernet & PoE:
The ER8400C is designed to communicate at up to 100Mbps per network port for Ethernet data
and transmit up to a Gigabit of aggregate LAN traffic. Additionally, the ER8400C provides per port power sourcing
PoE+ voltage to operate the transmitters (ET1500C), and up to 8 attached network devices. As a power sourcing
Layer 2 switch the ER8400 will supporting 15.4W (802.3af) to 25.5W (802.3at) powering schemes at a maximum
distance of 1600ft or 500m. Refer the PoE distance chart for specific power capabilities. Before installing this solu-
tion be sure that the cable involved does not exceed the recommended maximum lengths. If the cable length is in-
determinist at the time of installation, we recommend the use of a time domain reflectometer (TDR) which can
measure impedance characteristics, splices, and determine the cable length. The TDR does this through the use of
short rise time pulses.
