• the fabric lever remains fully open as shown in the figure "A fabric of
a Passport 15000, front view" (page 849)
• each rolling alignment bushing at the outside corners evenly enters
the 4 alignment grooves shown in the inset of the figure "Locations of
notches for fabric hinge bushings on Passport 20000 shelf assembly"
(page 850)
• the 4 guide pin keyway blocks at the rear corners of the fabric in the
figure "A fabric of a Passport 20000, rear view" (page 851) align with
the 4 guide pins on the backplane
5 Hold the fabric in place with one hand and close the fabric lever. Moving
the lever starts seating the fabric and requires a firm, steady motion to the
left against variable resistance. When the lever is almost closed, the
tension on it will lessen noticeably. Any squeaking is normal.
If inserting the fabric is stopped by a blockage, typically you can feel it but
not see it. When you feel blockage, stop the insertion and re-align the
fabric hinge pins. If the blockage persists, contact your Nortel Networks
technical support representative.
6 When the alignment bushings reach the end of the groove, the fabric lever
is almost fully closed. Fully seat the fabric and depress the reset button
by closing the fabric lever flush with the cover of the fabric.
Seating the NTPN02 requires slightly more force than an NTHR16 of a
Passport 20000. If the NTPN02 hinge bushings squeak during seating,
this is normal.
When pressed in, the fabric reset button enables the fabric to be loaded
with firmware when the switch is powered. Whenever the fabric reset
button is not fully depressed, the fabric cannot be put into service.
7 Tighten the captive screw on the lever to snug plus a 1/5 turn when
• all 4 alignment bushings are at the end of the alignment grooves
• the 4 corners of the fabric cover are evenly aligned with the
surrounding edges of the shelf assembly
• the fabric lever is closed flush
Avoid stripping the screw.
