The following sections guide you through the installation of an RF Module into a PRU chassis. The
process to install the four different types of RF Modules is basically the same; however,
differences are noted and should be followed.

NOTE:
In the following steps, the RF cables and connectors are referred to as MOD N TX0/RX0 and as
MOD N TRX1 where N equals A, B, C, or D.

Safety Precautions
CAUTION!
This is restricted access equipment and only qualified service personnel should service and
operate this equipment using appropriate tools.

CAUTION!
Wet conditions increase the potential for receiving an electrical shock when installing or using
electrically‐powered equipment. To prevent electrical shock, never install or use electrical
equipment in a wet location or during a lightning storm.
electrically‐powered equipment. To prevent electrical shock, never install or use electrical
equipment in a wet location or during a lightning storm.
CAUTION!
Always allow sufficient fiber length to permit routing of patch cords and pigtails without severe
bends. Fiber optic patch cords or pigtails may be permanently damaged if bent or curved to a
radius of less than 2 inches (5.1 cm).

CAUTION!
Exterior surfaces of the Prism Remote Unit may be hot. Use caution during servicing.
CAUTION!
Service personnel must confirm that the perimeter gasket and door‐to‐door gaskets are in place
when closing the Prism doors after servicing.

CAUTION!
This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously
damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly
into the optical transceiver of any digital unit or exposure to laser radiation may result. An
optical power meter should be used to verify active fibers. A protective cap or hood MUST be
immediately placed over any radiating transceiver or optical fiber connector to avoid the
potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles
from entering the adapter or connector.

CAUTION!
This system is an RF Transmitter and continuously emits RF energy. Maintain 3 foot (91.4 cm)
minimum clearance from the antenna while the system is operating. Wherever possible, shut
down the RAN before servicing the antenna.
