Installing a blank processor card
Install a blank processor card into an empty slot to ensure the effectiveness of
the cooling air flow and to maximize containment of electromagnetic
interference (EMI).
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You will need a blank processor card with PEC NTHR64. The faceplate
is labeled BLANK. See the figure “Blank processor card NTHR64”
(page 395). This card is also referred to as a filler module.
• Slots 0E and 1E are reserved for later development and must contain
blank cards in the meantime. Blank processor cards for these slots are
typically installed before a shelf is shipped.
Procedure steps
1 Locate an empty CP or FP slot in any cage.
2 At the ends of the faceplate, swing each latch fully open by pinching the
inner edge of the latch and lifting away from the faceplate. Refer to the
figure “Open card latches on a CP, FP, or blank processor card”
(page 576).
3 While holding each latch open horizontally, gently slide the card inwards
until it stops and the faceplate is flush with the shelf edges above and
below it.
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.
