Removing and Replacing the LED Board

Step 2:

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 7a).

Step 3:

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.

Step 4:

Push the panel upward to push the tabs into the slots (see Figure 7a) and pivot

the bottom of the panel toward the chassis until the panel frame meets the

chassis (see Figure 7b). Maintain a steady upward pressure to keep the guide

tabs in the chassis slots.

Step 5:

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 7c).

Step 6:

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 7d).

Step 7:

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 7d).

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.

Step 8:

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.

Step 9:

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.

This completes the chassis front panel removal and replacement procedures.

The LED board slides horizontally into two mounting brackets near the top of the

chassis interior and connects directly to the backplane. You must turn all system power

off and remove the top and bottom front chassis panels to access the chassis interior.

Warning:

Before accessing the chassis interior, turn the power switch to OFF (O)

and unplug the power cord. The backplane carries dangerous current levels.
