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

2
Unpack each container while carefully checking the contents for damage and verify with the packing slip.

If damage is found or parts are missing, file a claim with the commercial carrier and notify CommScope
Customer Service (see

Save all shipping containers for use if the equipment requires shipment at a future date.
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.
where N equals A, B, C, or D.
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:

Handle the RF Module with care during installation. Be especially careful to not damage the thermal-interface
material (TIM), which is attached to the LPA, DARTs, and/or Motherboard with TX/RX boards. If the TIM is
damaged, the LPA can overheat. Before installing the RF Module, check to see if the heatsink material is
gouged or cracked. If the TIM is damaged, do not install the RF Module and contact CommScope for assistance
(see
