Installing the PoE power supply
Perform this task to install the PoE power supply, connect it to the ODU, and prepare the
network cables.
If the PIDU is to be installed rather than the PoE power supply, refer to the
PTP 500
Series User Guide for PIDU installation instructions. This user guide is available from the
support website (see
Contacting Cambium Networks
on page
2
).
When using a PIDU note that Tx and Rx are crossed over, whereas with a PoE
adapter
Tx and Rx are wired straight through. This will only be apparent if 'Ethernet auto-
negotiation' is disabled - see
Step 1: LAN configuration
on page
6-13
.

Preparing for PoE power supply installation
The PoE power supply can be installed free standing, on an even horizontal surface or wall
mounted. Install multiple PoEs 1 cm apart.
The following guidelines should be adhered to before cabling the PoE power supply to the
Ethernet source and ODU:
x
Verify the device receiving power and Ethernet from the PoE power supply is a
PTP 250 ODU.
x
Do not block or cover airflow to the PoE power supply.
x
Keep the PoE power supply away from excessive heat, humidity, vibration and dust.
x
The PoE power supply is not a repeater, and does not amplify the Ethernet data signal.
Do not configure the cable length between the Ethernet network source, the PoE
power supply and the PTP 250 ODU beyond 100 meters (333ft).
The PoE power supply 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.
