Chapter 5: Installation
Installing the PSU
Install one of the following types of PSU (as specified in the installation plan):
•
PTP 650 AC Power Injector (Cambium part number N000065L001).
•
PTP 650 AC+DC Enhanced Power Injector (Cambium part number C000065L002).
Caution
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.
Caution
Do not plug any device other than a PTP 650 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 650 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 N000065L001):
1
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.
2
(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:
