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 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 installation on
page 5-29
• Mounting the PoE power supply on
page 5-30
• Connecting the PoE power supply to the dr
op cable on page 5-31
• Preparing the PoE power supply to network equipment cable on
page 5-32
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).
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.
