PoE Injector Cable Connection
The PoE Injector cables are connected similar to the PTP 820C.
• To connect the Ethernet (CAT5E) cable to the PoE or Data port, see Connection of Ethernet
Cable to PTP 820C on page 3-35.
• To connect the DC power cable to the power port or dual feed port, see Connecting a DC
Power Cable on page 3-27.
• The total length of the cable between the PTP 820C port and the Switch/Router the device is
connected to must not exceed 100m/328ft. This length includes the connection between the
PTP 820C and the PoE Injector (X1 + X2 ≤ 100m/328ft in the figure below).
Note
The length of the cable connecting the customer equipment to the PoE injector should
not be longer than 10m (according to ANSI/TIA-568 standard).
Note
For the warranty to be honored, the connection must be through the glands only. Do
not open the PoE injector box cover.
