Installing the AC Power Injector
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 PMP/PTP 450i Series 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 450 Platform 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.
