Installing the PoE power supply
Perform this task to install the PoE power supply, connect it to the ODU, and prepare
the network cables.
NOTE
If the PIDU is to be installed rather than the PoE power supply, refer to the
PTP 300 and PTP 500 Series User Guide (available for download at
www.motorola.com/ptp/software
) for PIDU installation instructions.
This task consists of the following procedures:
• Preparing for PoE power supply insta
llation on page 5-27
• Mounting the PoE power supply
on page 5-28
• Connecting the PoE power
supply to the drop cable on page 5-29
• Preparing the PoE power supply to network equipment cable on
page 5-30
Preparing for PoE power supply installation
The PoE power supply can be installed free standing, on an even horizontal surface or
wall mounted using wall mounting key holes on the underside of the unit. The
following guidelines should be adhered to before cabling the PoE power supply to the
Ethernet source and ODU:
• Verify the device receiving power and Ethernet from the PoE power supply is a
PTP 250 ODU.
• Do not block or cover airflow to the PoE power supply.
• Keep the PoE power supply away from excessive heat, humidity, vibration and
dust.
• 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).
CAUTION
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.
