Cabling rack
Inspect the cable rack for proper installation. The cable racks should be
at least 7 ft from the floor. The cable racks should be electrically tied
together with 6 AWG wire, except cable racks that are in an isolated
ground zone.
Fire protection
For indoor installations verify with the site manager that some type of
fixed fire suppression equipment is installed. The possible types are:
S Halon gas system, recommended for cell sites because:
– Halon extinguishes a fire without removing oxygen from a room.
– Halon is clean, allowing for quick cleanup after a fire.
– Halon will not damage the cell site equipment.
S CO
2
(carbon dioxide) system.
S Sprinkler system. “Dry pipe” sprinkler systems that remove all power
to a room before filling the overhead sprinklers with water are
recommended.
In addition to the fixed fire suppression equipment, there
should be at least two 5-lb ABC class portable fire
extinguishers on the premises before equipment installation
begins.
WARNING
Fire Fighting Procedures
Cellular infrastructure equipment contains various materials which can
decompose into toxic compounds during intense heat. When fire
fighting conditions are severe, wear full protective clothing, including
helmet, self–contained, positive pressure or pressure demand breathing
apparatus, bunker coat and pants, bands around arms, waist and legs,
face mask, and protective covering for exposed areas of the head.
Antenna cables and ports
Inspect the antenna cables and ports to verify that:
S All antenna cables have been properly labeled.
S Antenna ports have been properly weatherproofed.
S An adequate number of ports exist to handle all of the required
antenna runs.
S Lightning arrestors have been installed at the building or shelter entry
point.
S For some systems, special ports may be required (refer to the
site-specific information for further details).
