Understanding the pre-assembled Rox System
The Rox System cabinet seal typically ships pre-assembled and is ready to install. The pre-assembled Rox
System cabinet seal supports:
• Three radio sectors
• Each radio sector has two RF antenna cables. One cable carries two signals, a transmit signal and a
receive signal. The second contains a single receive antenna cable.
• Two GPS antenna cables — one primary GPS antenna and one redundant GPS antenna
The pre-assembled Rox System can be used on installations with:
• One, two, or three radio sectors. See Understanding radio sectors
on page 15.
If fewer than three radio sectors are used at a particular installation, the unused RF antenna cables
exiting through the Rox System cabinet seal must be connected to external surge suppression equipment
to prevent equipment damage from lightning strikes.
• Redundant and non-redundant Digital Module Kits.
Redundant installations use two GPS antennas; non-redundant installations use a single GPS antenna.
(See Understanding Digital Module Kit redundancy
on page 23.) In non-redundant installations, the
secondary GPS antenna cable must be connected to external surge suppression equipment to prevent
damage from lightning strikes.
The pre-assembled Rox System cannot be used for installations that have three separate RF antenna cables
for each radio sector. In this case, you must use a specially-ordered Rox System cabinet seal with nine RF
cables.
The pre-assembled Rox System is shipped fully assembled with cables that are 8 feet long, 3/8 inch or 1/2
inch in diameter, and have male N-Type connectors at both ends. See Table 18
.
NOTE
If you special ordered a Rox System cabinet seal, or assembled it yourself, you
might have a different number of cables and different connector types.
