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
TX1/RX1 where N equals A, B, C, or D.
TX1/RX1 where N equals A, B, C, or D.
NOTE:
When installing RF Modules, populate the RF Modules from highest frequency band to lowest within the
PRU. Likewise for power output, populate from the bottom bay to the top; higher output to lower
output. That is, for a deployment with 2100 40W, 1900 40W, 850 20W and 700 20W MIMO, install the
RF Modules as follows:

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

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.

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.
