Installing the PSU
Install one of the following types of PSU (as specified in the installation plan):
•
AC Power Injector (Cambium part number N000065L001C).
•
AC+DC Enhanced Power Injector (Cambium part number C000065L002C).
Attention As the PSU is not waterproof, locate it away from sources of moisture, either in the
equipment building or in a ventilated moisture-proof enclosure. Do not locate the PSU in a
position where it may exceed its temperature rating.
Attention Do not plug any device other than a PTP 650, PTP 670 or PTP 700 ODU into the
ODU port of the PSU. Other devices may be damaged due to the non-standard techniques
employed to inject DC power into the Ethernet connection between the PSU and the ODU.
Do not plug any device other than a Cambium PTP 670 PSU into the PSU port of the ODU.
Plugging any other device into the PSU port of the ODU may damage the ODU and device.
Installing the AC Power Injector
Follow this procedure to install the AC Power Injector (Cambium part number N000065L001C):
Form a drip loop on the PSU end of the LPU to PSU drop cable. The drip loop ensures that any moisture
that runs down the cable cannot enter the PSU.
(a) Place the AC Power Injector on a horizontal surface. Plug the LPU to PSU drop cable into the PSU
port labeled ODU.
(b) When the system is ready for network connection, connect the network Cat5e cable to the LAN
port of the PSU:

Installing the AC+DC Enhanced Power Injector
Follow this procedure to install the AC+DC Enhanced Power Injector (Cambium part number C000065L002C):
Mount the AC+DC Enhanced Power Injector by screwing it to a vertical or horizontal surface using the four
screw holes (two holes circled):
