Installing Cards in the Chassis
Installing Fabric Cards in the Chassis
Follow these steps to reinstall fabric cards (FCs) into the CiscoASR 9922 Router (see Figure 2-27 for
slot numbering) and CiscoA SR9912 Router (see Figure 2-31 for slot numbering).
Step1 Starting at slot FC0, slide the card into the slot.
Step2 Pivot the ejector levers to seat the card to the backplane connector.
Caution Do not apply excessive force to the FC to seat it. When seated, the FC ejector levers are angled slightly
outward from the card faceplate (item 1 in Figure3-4). When the captive installation screws are fully
tightened, the ejector levers are parallel to the card faceplate (item 2 in Figure3-4). Some flexing in the
backplane is normal. When you push the ejector levers fully vertical, the card is seated in the backplane
connectors. However, when you release the levers, backplane flexing pushes the levers out, so the levers
may be slightly loose. Tightening the captive installation screws prevents any additional movement from
flexing of the backplane.
Step3 Tighten the captive screws at the top and bottom of the front panel to a torque of 10 +/–1in-lb.
Step4 Repeat Step 1 through Step 3 to install the remaining FCs into slots FC1 to FC6.
Note Even when the FC is fully seated with installation screws fully tightened, there may be a slight gap
between the card and the chassis (item 3 in Figure 3-4).
Installing Line Cards in the Chassis
Before you begin reinstalling cards in the card cage, identify slot assignments by referring to the written
list you prepared when you removed the cards (see Figure2-20, Figure 2-22, and Figure 2-27, and
Figure 2-31 for slot numbering).
Caution Be careful to avoid damaging the EMI gasket that runs along the full height of the card front panel edges.
Damage to the EMI gasket can affect the ability of your system to meet EMI requirements.
Follow these steps to reinstall line cards in the chassis card cage:
Step1 Starting at the lowest numbered line card slot, slide the card into the slot (see Figure3-6, Figure 3-7,
Figure 3-9, or Figure 3-10) until it mates with the backplane connector.
Step2 Pivot the ejector levers to seat the card into the backplane connector.
Step3 Tighten the captive screws at the top and bottom of the front panel to a torque of 10 +/–1in-lb.
