Remove and Install the Back Cards
Step 5 Gently pull the front card out of the card cage. Keep the front card level and make sure that it does not
hit the one beneath it.
Step 6 Either replace the front card that you remove or insert a blank faceplate in the empty slot.
Install the Single-Height Front Cards
Complete the following steps to install single-height front cards in the chassis:
Step 1 Connect a grounding strap to the ESD grounding jack or to the equipment rack.
Step 2 See the “Card Installation Guidelines” section on page 2-9 to verify that there are no bent pins, bent
dividers, or damaged connectors on the front cards.
Step 3 Remove the plastic protective cover from the rear edge of the card, as shown in Figure 4-4. This cover
protects the alignment tabs during shipping.
Step 4 Verify that the extractor lever is in the unlatched position.
Step 5 Position the front card over the appropriate slot and align the front card edge with the slot guides (top
and bottom or left and right) in the chassis.
Step 6 Lift up and out on the extractor lever and gently apply pressure to the faceplate while pushing the front
card into the slot.
Step 7 Once the front card is installed in the chassis, apply even pressure to the top and bottom of the faceplate
to fully seat the front card.
Step 8 Press down on the extractor lever until it latches to secure the front card.
Note If you are installing the front card for the first time, refer to the configuration procedures in the
appropriate software configuration guide.
Remove and Install the Back Cards
The following sections describe how to remove and install a back card.
Tip We recommend that you label each cable and wire at both ends to identify its source and destination.
Note All cards must be fully seated in the chassis. When installing the back card, apply even pressure to the
top and bottom of the faceplate to make sure that the card is fully seated.
The card should slide in and out with only slight friction on the adjacent board’s EMI gaskets. Do not
force the card. Investigate any binding.
