How to Install or Remove a Switch Fabric Card
Step 5 Identify the card slot in the card cage where the switch fabric card should be installed.
a.If there is an impedance carrier in the slot, remove it (see the “Removing an Impedance Carrier” section on page
b.If there is a switch fabric card already installed in the slot, remove the card (see the “Removing a 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.
Step 7 Orient the route processor card so that the status display is on top, then position the card for insertion into the card cage slot. Avoid touching the card circuitry or any connectors.
Note 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.
Step 8 Grasp both card ejector levers simultaneously, then push them both outward until they are fully extended in the open position.
Step 9 Carefully slide the switch fabric card into the slot until the ejector levers meet the edges of the card cage, 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.
Step 10 To fully seat the card in the midplane connector, grasp both card ejector levers simultaneously, then push them both inward until they are flush against the front edge of the card carrier.
Caution 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.
Note 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.
Step 11 To seat the card firmly in the slot, use the screwdriver to tighten the captive screws.
What to Do Next
After performing this task:
•Place the impedance carrier in an antistatic bag for storage and future use.
•If you are performing the initial installation of the system, install the RPs (see the “Installing an RP Card” section on page
