Chapter 4 Installing and Removing a SPA Interface Processor
Removing and Installing a SIP
Caution When you install a SIP, always use the ejector levers to ensure that the card is correctly aligned with the
backplane connector, the card connector pins make contact with the backplane in the correct order, and
the card is fully seated in the backplane. A card that is only partially seated in the backplane can cause
the router to hang and subsequently crash.
Step 5 Simultaneously pivot both ejector levers toward each other until they are perpendicular to the SIP
faceplate. This action firmly seats the card in the backplane.
Step 6 Use a 3/16-inch flat-blade screwdriver to tighten the captive installation screw on each end of the SIP
faceplate to ensure proper EMI shielding and to prevent the SIP from becoming partially dislodged from
the backplane.
Caution To ensure adequate space for additional SIPs, always tighten the captive installation screws on each
newly installed SIP before you insert any additional SIPs. These screws also prevent accidental removal
and provide proper grounding and EMI shielding for the router.
Step 7 Install the SPAs. Refer to Chapter 5, “Installing and Removing a Shared Port Adapter”.
Step 8 Install the SFP modules in the SPAs that use them. Refer to Chapter 5, “Installing and Removing a
Shared Port Adapter”.
Step 9 Install the interface cables.
