Lightning/Surge Protection
To provide for human safety and for the safety of connected network equipment, it is highly
recommended to place a weatherproof lightning suppression device at the egress point where the
Ethernet cable(s) enter the building, shelter, or cabinet.
To protect the radio equipment, install a weatherproof lightning suppression device near the radio for
all connected Ethernet cables.
For the Power/Ethernet cable, specific voltage requirements must be met. The following devices are
the only devices currently recommended:
•
Polyphaser IXG-05
Generally, use a short Ethernet cable supplied for the connection between the radio and the first
arrestor. Use bulk outdoor-rated CAT5e or CAT6 cable for the longer run between arrestors, and
indoor- or outdoor-rated cable with a standard Ethernet termination for the connection from the egress
arrestor and power injector.
Apply this same cabling method for the TDM connections. There are no special requirements for
lightning arrestors. Vendors, such as Transtector and Polyphaser, offer single and multiple TDM
weatherproof arrestors. Note that each connector on the radio can carry up to 2 TDM (Time Division
Multiplexing) connections.
Reset to Critical Factory Settings
If necessary, the radio terminal may be reset to critical factory settings. This may be necessary if the IP
address and/or passwords for the system are not known. All other configurations are left at their
current settings. If a complete default factory configuration is desired, load the Default Configuration
File into the system, as described in
.
The following parameters are configured after a reset to critical factory settings:
•
IP Address = 10.0.0.1
•
IP Mask = 255.0.0.0
•
IP Gateway = 0.0.0.0
•
Administration password = password
•
User password = password
Antenna/Transmission System
This section provides guidance to mounting and connecting the RF transmission system, which
consists of the antenna, RF cabling, and RF lightning arrestors. Consult the manufacturer’s instructions
for proper mounting, grounding, and wiring of these devices, and for definitive direction. These
manufacturer’s instructions supersede any information in this section. See
for a list of
supported antennas.
Note:
Use only outdoor-rated UV-resistant CAT5e or CAT6 cable. This cable must have an
outer diameter between 0.25"/6.35 mm and 0.31"/7.87mm. Belden 1300A is recommended.
Securely hand-tighten all connectors on the ODU to ensure a weatherproof seal.
