CAUTION
Risk of equipment damage and service loss by bent
pins
Attempting to seat a fabric with at least one bent connector
pin risks damaging the backplane connectors such that
another fabric with straight pins cannot be seated, risks a
short across other pins, and risks bending more pins. The
field replacement for any damaged backplane connector is
to replace the shelf assembly. If you have any doubts about
the straightness of the pins on the fabric, use another fabric
with straight pins or contact your next level of technical
support.
4 Stand the fabric on its bottom and unfasten the Phillips captive screw on
the handle. It is normal for the handle to open slightly.
5 Align the fabric bushings at the 4 corners of the fabric chassis on the shelf
assembly with the nearest transportation notch (identified in the figure
"Locations of notches for fabric hinge bushings on Passport 20000 shelf
assembly" (page 445).
6 Place the alignment bushings into the 4 transportation notches as shown
in the figure "Locations of notches for fabric hinge bushings on
Passport 20000 shelf assembly" (page 445).
7 While holding the fabric by one handle, pull the fabric lever slowly towards
you until it stops perpendicular to the face of the fabric. While the lever
opens, the alignment bushings at the 4 corners of the fabric move
inwards. The transportation notches are angled so that opening the fabric
lever rolls the alignment bushings out of the notch and into the opening of
the alignment grooves. See the figure "Locations of notches for fabric
hinge bushings on Passport 20000 shelf assembly" (page 445).
If the lever does not move or any of the 4 alignment bushings is catching,
close the lever and re-align the fabric by very gently jiggling it. Try opening
the lever again.
8 Once the 4 bushings are at the start of the alignment grooves, place a
hand in each fabric handle and gently push the fabric into the shelf such
that
• the fabric lever remains fully open as shown in the figure "A fabric of
a Passport 20000, front view" (page 444)
