Removing and Installing Switch Fabric Cards

Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection

sockets on the front of the chassis or to a bare metal surface on the chassis (see Figure 3 on page 10).

Step 2 Grasp the card carrier handle with one hand and place your other hand under the carrier to support and

guide it into the correct slot. Slide the card halfway into the slot. Avoid touching the card circuitry or

any connectors.

Note There are alignment grooves on each slot in the fabric card cage. When you reinstall a card in

the fabric card cage, make sure that you align both edges of the card carrier in the slot grooves.

Step 3 Pivot both card ejector levers so the openings on the card ejector cams at the top and bottom of the card

pass over the tabs on each side of the card cage slot.

Caution Verify that the openings on the card ejector cams pass over the tabs; otherwise, one or both ejector levers

might bind when you attempt to close the ejector levers, thereby damaging or breaking one or both

ejector levers.

Step 4 Continue sliding the card into the card cage slot until the openings on the card ejector cams engage the

tabs on each side of the card cage slot.

Note CSCs and SFCs have guide pins that make initial contact with the backplane connector as you

slide a card into its slot. After the guide pins make contact, continue pushing on the card carrier

until the card ejector levers begin pivoting forward, toward the handle in the card carrier.

Step 5 To seat the card in the backplane connector, grasp both card ejector levers and pivot them inward toward

the handle in the card carrier until they are flush against the front edge of the card carrier.
