Removing and Replacing the Rack Doors
WARNING:
Never attempt to remove or install the rack cabinet doors by yourself.
Due to the size and weight of the rack cabinet doors, this procedure requires at
least two people.
Removing the Front Door
1 Open the rack door. See "Opening and Closing the Front Rack Door" on
page 9.
2 While holding the door, remove the hinge pins starting from the bottom of the
rack. Ensure that the top hinge pin is the last pin to be removed from the door.
To remove the hinge pin:
a Pull the hinge pin so that it clears the hinge-pin housing on the door.
For the hinge pins located at the bottom of the door, pull the two
hinge pins downward. For the hinge pins located at the top of the
door, pull the two hinge pins upward. See Figure 1.
The hinge pin's retention clip prevents the hinge from being
completely pulled out of the hinge body.
b Pull the door slightly away from the rack so that the door clears the
hinge body.
WARNING:
When storing the doors, lay the doors flat so they do not fall over
and accidentally injure someone.
WARNING:
Due to the size and weight of the door, it is recommended that you lay
the removed door flat with its outer surface facing upward.
3 Lay the door in a safe location with the door's outer surface facing upward
to prevent damage to the door's badge and cosmetic coating.
