Installing the PIDU
Mounting the PIDU
Mount the PIDU on a wall or other suitable mounting surface, at a height that protects
it from flooding or rising damp. Ensure that the Recovery switch can be accessed when
mounting the unit.
The PIDU is not waterproof and should be mounted away from sources of moisture. If
mounted outdoors, the unit should be mounted in a moisture proof enclosure,
preferably ventilated.
Connecting the PIDU to the ODU cable
Plugging other equipment into the ODU RJ45 socket may damage the equipment due
to the non-standard techniques employed to inject DC power into the 100BaseT
connection between the PIDU and the ODU. Plugging the ODU into other equipment
may damage the ODU and/or the other equipment.
Do not dress the PIDU cables too tightly, as this may make the connections unreliable.
The connected network equipment must feature screened RJ45 connectors and must
be connected to ground, otherwise the PIDU will not be grounded.
To connect the PIDU to the cable from the ODU, proceed as follows:
1
Form a drip loop on the PIDU end of the LPU-PIDU drop cable. The drip loop
ensures that any moisture that runs down the cable into the cabinet or enclosure
cannot enter the PIDU.
This should be done first in order to avoid straining the RJ45 connector.
2
Fit an RJ45 connector (but no gland) to the PIDU end of the LPU-PIDU drop
cable.
3
Undo the retaining screw and hinge back the cover.
