3 If no pins are bent, proceed with the installation of the switch hardware.
If at least one pin is bent slightly or worse, abort the installation of the
switch hardware and contact your local Nortel Networks technical support
prime to arrange having the shelf assembly replaced. You must identify
the PEC that is labelled on the shelf assembly as one of the following:
• NTHR50 or NTHW99 for a Passport 15000
• NTPN70 or NTPN77 for a Passport 20000
4 If replacing an unmounted and empty shelf assembly, put it back in its
shipping container.
If replacing a mounted shelf assembly, wait for the replacement and then
replace it according to “Shelf assembly replacement” (page 218).
When returning a shelf assembly, always leave the pre-installed PIMs,
MAC address module, and alarm/BITS module in the assembly. The
replacement shelf assembly always includes these modules.
CAUTION
Risk of equipment damage and service loss by bent
pins
When at least one backplane pin is bent, attempting to seat
a processor card risks damaging the backplane connector
and the card such that neither the card nor the slot can be
used. If you have any doubts about the straightness of the
pins on the backplane, contact your local Nortel Networks
technical support representative to decide whether the
shelf assembly should be replaced.
