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.
NOTE: When installing RF Modules, populate the RF Modules from highest frequency band to lowest
within the Remote Unit chassis. 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:
• 2100 40W RF Module in Bay A
• 1900 40W RF Module in Bay B
• 850 20W RF Module in Bay C
• 700 20W MIMO RF Module in Bay 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.
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 Remote Unit 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.
