Chapter 4 Installing option cards and field replaceable units 65
3 Grip the two handles and firmly pull the bezel toward you to unsnap it from
the chassis.
The first few times that you remove the front bezel, it may be somewhat
difficult to remove because the ball studs and socket clips are new.
Note: If you are replacing a hard disk drive, you do not need to remove
the chassis from the equipment rack; go to
on page 83.
If the Contivity 5000 is installed in an equipment rack, you must remove it from
the rack to add or replace DIMMs, option cards, or fan trays.
To remove the chassis from the rack:
1
At the front of the chassis, remove the two 1/2-in. truss screws that secure the
bottom of the chassis to the equipment rack.
Warning: The Contivity 5000 weighs approximately 50 pounds (23 kg).
This weight is not evenly distributed; the right side of the gateway
weighs more than the left. For this reason, two people should remove the
system from the equipment rack.
2
With two people facing the front of the equipment rack, remove the Contivity
5000 from the rack-mount shelf and set it on a sturdy surface.
To remove the top cover:
1
Using a Phillips screwdriver, remove the 4 screws that secure the cover to the
chassis (Figure 24).
2
Slide the top cover forward approximately 1/4 inch.
