Go to the rear of the chassis. Attach the ESD-preventive wrist strap to your wrist and connect its leash
Step 1
to one of the ESD connection sockets on the rear (SFC) side of the chassis or a bare metal surface on the
chassis.
Step 2 Remove the switch fabric card from its antistatic packaging.
Use a medium Phillips screwdriver to remove the switch fabric card from its protective carrier.
Step 3
Visually inspect the connector pins on the card before you insert it into the chassis.
Step 4
Note
Identify the card slot in the card cage where the switch fabric card should be installed.
Step 5
If there is an impedance carrier in the slot, remove it (see the
a.
section on page
If there is a switch fabric card already installed in the slot, remove the card (see the
b.
Switch Fabric Card" section on page
Step 6 Grasp the face plate of the card with one hand and place your other hand under the card to support and
guide it into the correct slot.
Orient the route processor card so that the status display is on top, then position the card for insertion
Step 7
into the card cage slot. Avoid touching the card circuitry or any connectors.
Note
Grasp both card ejector levers simultaneously, then push them both outward until they are fully extended
Step 8
in the open position.
Carefully slide the switch fabric card into the slot until the ejector levers meet the edges of the card cage,
Step 9
then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try reinserting
the switch fabric card until the ejector lever hooks are fully latched.
To fully seat the card in the midplane connector, grasp both card ejector levers simultaneously, then push
Step 10
them both inward until they are flush against the front edge of the card carrier.
Caution
Note
To seat the card firmly in the slot, use the screwdriver to tighten the captive screws.
Step 11
OL-10971-10
Do not attempt to install a card with bent pins, because this may damage the chassis midplane
connectors.
4-10.)
There are alignment grooves on each slot in the card cage. When you install a card, make sure
that you align both the top and bottom edges of the card carrier in the slot grooves.
Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both
ejector levers may bind when you attempt to close the levers, thereby damaging or breaking
one or both of them.
Switch fabric cards have guide pins that make initial contact with the midplane connector as you
slide a card into its slot. After the guide pins make contact, continue pushing the card carrier
until the card ejector levers begin pivoting forward.
