Removing a blank processor card
Remove a blank processor card to replace it with an FP or CP.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• A blank processor card has PEC NTHR64 and is labeled with BLANK
on the faceplate.
Procedure steps
1 At the front of the Passport 15000 or 20000, locate the blank card to be
removed. See the figure “Locations of FPs” (page 753). Blank cards are
labeled with BLANK.
2 On the faceplate of the blank card, fully swing out the upper and lower
latches until they stop. See the figure “Fully opened card latches”
(page 754).
3 Place fingers on the exposed tabs to gently but firmly slide the card out of
its slot.
4 Put the card aside into the spare anti-ESD package and pack it later.
5 Store any removed blank card for re-use in another slot. No slot of a
Passport 15000 or 20000 is to remain empty for more than a few minutes
while the switch is powered up, especially if it is operating at full service.
CAUTION
Risk of service degradation or equipment damage
Always have a blank processor card (labeled BLANK) in a
slot that does not house another card. The blank cards
enable efficient performance of the fans for temperature
control and also facilitate fire protection and EMI
containment.
