3 Orient the fabric such that the black alignment arrow on the fabric casing
points to the arrow on the shelf. See the arrow in the figure "A fabric of a
Passport 15000, front view" (page 436).
4 Align the 4 guide pins on the backplane with the 4 keyway holes in the rear
of the fabric. See the keyway holes in the figure "A fabric of a
Passport 15000, rear view" (page 437). The keyway hole pattern is
asymmetrical in only 1 orientation so that either fabric is installed in only
1 way.
5 Insert the hinge pegs of the pair of covers into the curved channels at the
center. See these characteristics in the figure "Location of the curved
channels for the Passport 15000 fabric hinge pins" (page 438). Ensure
that the top and bottom pegs are seated all the way in; otherwise, damage
can occur to the fabric when the casing is closed. You may have to jiggle
the pins very gently into place.
6 Slowly move the fabric to engage the keyways over the guide pins.
7 While holding the fabric against the curved channels, unfasten the Phillips
captive screw on the fabric cover and open the casing by pulling the fabric
lever towards yourself. Stop when the lever touches the casing on the
opposite side.
8 Seat the fabric onto the backplane using gentle, even force, and
simultaneously close the casing by closing the lever. The closing action
seats 1 side of the fabric sooner than the other.
9 Close the casing flush with the surrounding perimeter (shelf assembly).
10 Align and fasten the captive screw until snug plus a 1/5 turn.

CAUTION
Risk of equipment damage
If you feel resistance against the fabric while seating it, do
not force it. Re-align it and if there is still more resistance,
remove the fabric and look for an obstruction, a bent guide
pin, or a bent hinge pin.
