* An RUC in slot A2 will connect to PAAs 1 and 2. An RUC in slot A5 will connect to PAAs 3 and 4.
Therefore, the RUC front panel indicators of 1/3 and 2/4 will map to PAAs 1 and 2 connections in slot
A2 and PAA 3 and 4 connections in slot A5.

Fan Access Panel
The Fan Access Panel, shown in
, has a hinged front panel that swings down providing
access to the two fans cooling the RAN chassis. These fans are user-replaceable. This panel has
labels identifying the electronic modules located in the cPCI shelf below the panel.

800 MHz Multicoupler (C/MCPLR)
The 800 MHz (C/MCPLR) Module is a cPCI electronic module that houses the dual-diversity,
receive unit for the 800 MHz bands. This module interfaces to the multiplexer system and
contains the front end low noise amplifiers for the reverse path. The module has six outputs
(Cell bands A, B, and 800 MHz, with diversity).
