This completes the chassis front panel removal and replacement procedures.
While pushing slightly against the top of the panel to constrain it, pivot the bottom edge of
the frame outward about 2 inches. (See Figure 5-28a.) Because of the tightly compressed
EMI shielding, you will have to use significant force to pull the bottom of the panel
outward. However, be careful that you do not pull the panel more than 2 inches away from
the chassis, or you may damage the inner bezel or LED board.
When the bottom of the frame clears the chassis opening, keep your hands in the same
positions and pull the panel down and OFF the chassis. (See Figure 5-28b.)
Grasp the sides of the top panel with both hands. (See Figure 5-29a.)
Two guide tabs at the top edges of the panel fit into two slots in the top edges of the chassis
opening. Tilt the top of the panel back (away from you) about 30 degrees from vertical and
slide the two guide tabs into the chassis slots. (See Figure 5-29a.)
Check the top of the panel and make sure it is lined up with the top of the chassis opening.
Failure to align the panel at this point can result in equipment damage when performing the
next step.
Push the panel upward to push the tabs into the slots (see Figure 5-29a) and pivot the
bottom of the panel toward the chassis until the panel frame meets the chassis. (See
Figure 5-29b.) Maintain a steady upward pressure to keep the guide tabs in the chassis slots.
When the panel is flush against the front of the chassis, push the panel upward until the
bottom of the panel is level with the bottom of the chassis opening. (See Figure 5-29c.)
Place the palm of one hand against the top front center of the panel to brace it and hold it
in place, and place the palm of your other hand against the lip on the bottom edge of the
frame. (See Figure 5-29d.)
Use your hand at the bottom of the frame to push the bottom of the panel upward and back
into the chassis opening until the tabs on the front sides of the panel are flush against the
front of the chassis. (See Figure 5-29d.) You will have to use significant force to compress
the EMI shielding enough to fit into the opening. If the panel resists, pull it slightly
downward and make sure that the panel is lined up with the top and sides of the opening in
the chassis.
When the tabs on the front sides of the panel are flush against the sides of the chassis,
tighten the two captive screws in the bottom edge of the frame.
To replace the bottom front panel, place the ball studs on the back of the panel over the
holes in the front lip of the chassis and push the panel onto the chassis until the ball studs
snap into place. (See Figure 5-29e.)
