Step 3. Slide each flange down until the flanges drop out of the five retaining clips that hold them to the
Shelf.
Step 4. Set the flanges aside.
To replace the rack mounting flanges, complete the following steps:
Step 1. Position each flange over the five retaining clips on each side of the 14-Slot Shelf chassis for either
the 4-post or 2-post mounting position, as required for your installation. Ensure that the flange
retaining clips on the chassis protrude into the five rectangular-shaped cut-out openings in the
flange body.
Step 2. Ensure that the protruding right-angle flange surfaces that mate to the equipment rack are
oriented toward the front of the 14-Slot Shelf blade cage (see Figure 1-14, flange mounted in
position for 4-post rack installation).
Step 3. Slide each flange up under the flange retaining clips until the flanges are securely seated under
each clip. The rack mounting flange screw holes should now be aligned with mating threaded
receptacles in the 14-Slot Shelf body.
Step 4. Insert two retaining screws into each rack mounting flange and tighten.
Step 5. The 14-Slot Shelf is now ready to be mounted into a four-post equipment rack.
