The PIDU Plus to ODU and the PIDU Plus to Network Equipment cables may be unscreened
(UTP) or screened (STP). However, unscreened cables reduce the system’s ability to cope
with nearby lightning strikes. If lightning activity is common in the area of deployment, the use
of screened cable is highly recommended. See Section 10 “Lightning Protection”.
The PIDU Plus provides screen continuity between the ODU and Network Equipment
connections.
The ODU network connection implements automatic MDI/MDI-X sensing and pair swapping
allowing connection to another piece of networking equipment or directly to end user
equipment.
3.3.6 Surge Arrestor
The PTP 600 Series Bridge PIDU Plus meets the low level static discharge specifications
identified in Section 21 “Specifications”, but does not provide lightning or surge suppression.
Installations will generally require lightning or surge suppression, a separate Ethernet surge
suppressor must be used and appropriately earthed. Suitable surge suppressors can be
sourced from your Motorola Point-to-Point Distributor or Solutions Provider. See Section 11
“Lightning Protection”.
3.3.7 Mounting Brackets
The PTP 600 Series Bridge is supplied with a mounting bracket suitable for mounting the
ODU to a pole of 50mm (2”) to 75mm (3”) in diameter. For more details on mounting, see
section 7 “Installation”.
The bracket allows for adjustment in both azimuth and elevation. The bracket may be split
allowing the pole mount section of the bracket to be mounted to the pole first. This allows the
installer to take the weight of the unit and secure it, one handed, with a single mounting bolt.
The PIDU Plus can either be desk or wall mounted. The preference is wall mounted with the
cables dressed to a cable channel. Wall mounting is achieved by screwing through the
mounting lugs on either side of the unit. Remember to leave space for access to the
Recovery button. See section 3.3.2.
