Installing a fabric card into a Passport 15000
Install a fabric card into the rear of a Passport 15000 to
• complete a fabric replacement and restore the load-sharing mode of
operation
• initially install it in preparation for powering up the system
• complete an alarm/BITS replacement
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need a Passport 15000 fabric with PEC NTHR16.
Procedure steps
1 Hold the fabric so that you have one hand on the handle and one on the
lever as indicated in the figure “A fabric of a Passport 15000, front view”
(page 436).
2 Check each row of backplane connector pins to see whether any pin
seems visibly bent, that is, even slightly out of pattern or worse. If at least
one pin is slightly bent or worse, use another fabric with straight rows of
pins. The pins are shown in the figure “A fabric of a Passport 15000, rear
view” (page 437).
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.
