Front Bezel Removal
The front bezel is a requirement for complete RFI shielding. The
bezel is latched on both sides. Screwdriver-operated locks at the
upper corners prevent the latches from being arbitrarily
disengaged. The latches are to be opened by trained service
personnel only.
The 9U bezels for the dual 9-, 12-, and 20-slot card cage and OEM
equipment enclosure are mounted on ball studs at the bottom and
latched at the top; the 3U bezels used elsewhere are simply latched.
Refer to Figure 2-5 on page 2-13 and Figure 2-6 on page 2-14 while
performing this procedure.
1. Unlock the bezel latches by rotating the locks a quarter-turn
inward from the “locked” icon to the “unlocked” icon with a
Phillips screwdriver (clockwise on the left side,
counterclockwise on the right).

Caution
To avoid damaging the keyswitch assembly when you
remove card cage bezels, make sure that the key is
removed before you unlatch the bezel.
2. Unlatch the bezel from the enclosure by pressing the latch
buttons at either side of the bezel and pulling straight out
until the bezel latches are clear of the chassis. (If it is a 3U
bezel, removal is complete at this point.)
3. (For 9U bezels): Release the bottom of the bezel from the ball
studs by firmly grasping the lower edge and pulling straight
up.
