8 Cisco 7000 and Cisco 7507 Air Filter and Chassis Blower Replacement Instructions
With your other hand, grasp the front of the panel by inserting your fingers into the opening
on the underside of the bezel. (See Figure 4a.)
While pushing slightly against the top of the panel to constrain it, pivot the bottom edge of
the frame outward about two inches. (See Figure 4a.) 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 two inches away
from the chassis, or you can 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 downward and off the chassis. (See Figure 4b.)
Grasp the sides of the top panel with both hands. (See Figure 5a.)
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 5a.)
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 5a) and pivot the bottom
of the panel toward the chassis until the panel frame meets the chassis. (See Figure 5b.)
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 5c.)
While holding the panel in place, place one palm against the top front center of the panel
to brace it, and place the other against the lip near the bottom edge of the frame. (See
Figure 5d.)
Push 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 5d.) 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.
