Grounding the Unit
There is a grounding connector on the top panel of the device. Use this connector to connect a well-
grounded mounting surface, such as a metal panel. Grounding and wire routing help limit the effects of
noise due to electromagnetic interference (EMI).
ATTENTION
A shielded power cord is required to meet the FCC emission limits and to prevent interference with nearby
radio and television reception. It is essential that only the supplied power cord be used.
You are cautioned that changes or modifications not expressly approved by the party responsible for
compliance could void your authority to operate the equipment.

The Ethernet ports are located on the front panel of the device. The pin assignments for the Ethernet port
are shown in the following figure. If you are using your own cable, make sure that the pin assignments on
the Ethernet cable connector match the pin assignments on the Ethernet port.
