45 Mbps Backhaul User Guide
Issue 3, December 2004 Page 11 of 113
Since the connection from the PIDU to the ODU is part of network infrastructure and is often operating in a
high RF environment due to nearby equipment and the potential for lighting-induced currents, the use of
shielded cables is strongly recommended.
The connection between the PIDU and user’s equipment can be made using any standard CAT5 patch cable.
The RJ45 Ethernet connection is presented as a piece of network equipment. However as automatic
MDI/MDI-X sensing and pair swapping is employed a crossed or no crossed Ethernet patch cable can be used
for connection to another piece of networking equipment or directly to end user equipment.
The PIDU provides continuity between the shield on the ODU-PIDU cable and the shield on the PIDU-User
equipment cable. If continuity of the shielding is desired from the ODU-PIDU to the user’s equipment, CAT 5
STP cable and connectors should be used for the latter connection. CAT5 STP cable between the PIDU and the
user’s equipment will provide additional protection against surges induced on the Ethernet connections.
1.3.5 Surge Arrestor
The PIDU does not provide lightning or surge suppression. Lightning and surge suppression should be
provided by a separate Ethernet surge suppressor appropriately grounded. Suitable surge suppressors can
be sourced from your Motorola distributor or reseller. The ODU is protected by built-in surge suppression as
standard. See 9 “Lightning Protection”.
1.3.6 Mounting Brackets
The 45 Mbps Backhaul is supplied with a mounting bracket suitable for mounting the ODU to a pole of 50mm
to 75mm in diameter or to a flat surface. For more details on mounting, see section 5 “Installation”.
The bracket allows for adjustment in both azimuth and elevation. The bracket may be mounted to the pole or
wall prior to installation. This allows the installer to take the weight of the unit on a single mounting bolt while
fitting the retaining nut and washers.
The PIDU 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 reset button. See section 5.7.7.
1.3.7 Configuration and Management
Configuration and Management of the 45 Mbps Backhaul is implemented using an inbuilt web server hosting a
number of Configuration and Management web pages. This approach allows Configuration and Management to
be carried out on any standard web browsing technology. The 45 Mbps Backhaul can also be managed remotely
using the SNMP management protocol. Connection to the 45 Mbps Backhaul is via the Ethernet connection
carrying the bridge network traffic. Connection to the unit is via a preset IP address. This address can be
changed via the Network Interface Configuration web page. A full explanation of the available web pages and
their use can be found in section 6 “Web Page Reference”.
