2.11 Mounting Requirements
The GMA 342/345 mounting surface must be capable of providing structural support and electrical bond to
the aircraft to minimize radiated EMI and provide protection from High-Intensity Radiation Fields (HIRF).
The GMA 342/345 is mounted using a GMA unit rack (Figure 2-4). See Section 3.6
for installation
instructions.
NOTE
Rear support is recommended to ensure a sturdy mount.
CAUTION
The top cover of the unit has a connector number (1 and 2) stamped into it and centered in
front of each connector. The 011-00678-00 backplate also has a stamped number on it. To
prevent damage to the unit, verify the connectors are positioned correctly (connector 1 is
connected in position 1) for the number 1 and number 2 locations. The stamped number 1
refers to J3401, and 2 refers to J3402.
