Warning The 30/60 Mbps PIDU is not waterproof and should be mounted away from sources of
moisture. If mounted outdoors the 30/60 Mbps should be mounted in a rainproof enclosure,
preferably ventilated.
It is also recommended that you fit a drip loop on the 30/60 Mbps PIDU to ODU cable to ensure
that any moisture that runs down the cable into the cabinet or enclosure cannot enter the 30/60
Mbps PIDU. As shown in Figure 21. The network connection and mains cable should be treated
in the same way if there is a risk that they can carry moisture to the 30/60 Mbps PIDU.
To ODU
WARNING It is possible for moisture to enter the cable due to damage to the outer protective
layer. This moisture can track down the inside of the cable, filling up the drip loop and eventually
finding its way into the 30/60 Mbps PIDU. To protect against this the outer protective layer of the
cable can be opened up at the bottom of the drip loop to allow this moisture to escape.
WARNING Some network operators employ gel filled cables to get around the problem of
moisture ingress and transmission. 30/60 Mbps Backhaul has NOT been tested using these
cables. Use of gel filled cables may affect the performance of the 30/60 Mbps Backhaul.

Powering Up
The Canopy 30/60 Mbps Backhaul system is supplied as a pair of matched Master/Slave units.
The Master unit to be configured can now be powered up and accessed using the default URL
http://169.254.1.2
Prior to powering up the 30/60 Mbps Backhaul, a computer with web browsing capabilities
should be configured with an IP address of 169.254.1.n and subnet mask of 255.0.0.0 where n
is any value between 1 and 254 but excluding 1 or 2. If the default address of the unit
169.254.1.1/2 clashes with an address you are already using on your LAN, or you are not sure,
you should set up an isolated LAN. As the LAN connection presented at the 30/60 Mbps PIDU
has a default configuration as a hub/switch (and auto-sensing MDI/MDIX cross over is
employed) connection can be made directly to the computer using a standard CAT 5 patch
cable.
