MGX 8850 System

Installing Backplane Plastic Insulating Cover

Use the following procedure to install the insulating cover over a system’s backplane. This procedure
may be done without powering down the system.

Step 1 Open the plastic grill on the front side of the intake plenum, located directly underneath the card cage

or the fan space, using a flat blade screw driver to loosen the two recessed screws. Tilt the plastic grill
forward about 45 degrees, then lift out and set it aside.

Step 2 Hold the plastic cover, shown in the drawing below, so that the 16 short tabs are facing towards you.
