1.3 Mechanical Description
The GLU-2100 is packaged in an ARINC 600 size 3 MCU case. A low insertion force
size 2 connector on the rear of the unit interfaces with the aircraft wiring. The connector
also holds the rear of the unit to the equipment rack. The GLU-2100 is cooled with
forced-air supplied to inlet holes on the bottom of the unit and exhausted through outlet
holes on the top of the unit.

The GLU-2100 chassis consists of top and bottom plates, front panel, left and right
hinged swingout side covers, and a rear connector mounted in an assembly that protects
against high intensity radiated fields (HIRF). The top insert of the rear connector is for
the GNSS antenna connection, the middle insert is for service connections and VOR/MB
antenna connections, and the bottom insert is for power and LOC/GS antenna
connections.
