.

Eight front panel securing screws
Numbers are for tightening order on reassembly

6. View the Genesis MP from the front. Cable assemblies pass

between the front panel and the chassis on the right-hand side
of the front panel assembly. To remove the front panel, carefully
open it like a door (

note: the assembly is NOT supported by

hinges), pulling the left edge toward you while keeping the right
edge close to the Genesis MP Chassis.

IMPORTANT

The front panel will be restrained by wiring for various subassem-
blies attached to it. be careful not to strain the attached wires while
the front panel is in this position.
Support the Genesis MP Front panel so that it does not fall and
stress cable subassemblies or cause damage to the metal, the
fasteners or the attached LED, Power Switch and Speaker sub-
assemblies.

From this position, you should be able to access cables and sub-
assemblies mounted to the front panel. Observe and note factory
cable routing and cable-tie points before further disassembly.

Replacement is the reverse of removal with the following exceptions:

1. Ensure the proper routing of power switch, LED, speaker, drive

power and fan cable assemblies. Refer to sections Speaker
Cable/LED Cable/Power Switch Cable Routing 
and Drive
Power/Fan Power Harness Routing
