Removing and Installing a CSC or SFC
Installing a Card in the Switch Fabric and Alarm Card Cage
To install a CSC or an SFC, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD sockets on
the front of the chassis or to a bare metal surface. (See Figure 4 on page 9.)
Step 2 Remove the replacement card from its antistatic bag or ESD-preventive container.
Step 3 Determine the assigned card slot for the card by checking the label attached to the edge of the card carrier
(near the bottom ejector lever). This will be the slot from which you just removed a CSC or an SFC.
Clock and scheduler cards are labeled CSC and are installed in the two far left slots; switch fabric cards
are labeled SFC and are installed in the next five slots. Alarm cards are installed in the last two slots.
Note Alignment grooves exist on each slot in the switch fabric and alarm card cage. When you
reinstall a card in the switch fabric and alarm card cage, make sure you align the top and bottom
edges of the card carrier in the slot grooves.
Step 4 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.
Step 5 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, damaging or breaking one or both ejector levers.
Note 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.
Step 6 To seat the card in the backplane connector, grasp both card ejector levers and pivot them inward toward
the middle of the card carrier until they are flush against the front edge of the card carrier.
Closing the Air Filter Door
To close the air filter door, follow these steps:
Step 1 Grasp the sides of the air filter door front cover and pivot the air filter door up so that it is aligned with
the opening of the switch fabric and alarm card cage, and the two guide pins are inserted in the
corresponding holes on each side of the switch fabric and alarm card cage.
