Installing and Removing a SPA Interface Processor
Caution
The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only
one SIP at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing
or inserting another SIP.
To install a SIP, follow these steps:
Step 1
Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2
Choose an available SIP slot for the SIP, and verify that the SPA interface cables are long enough for you to connect the
SIP with any external equipment.
To prevent ESD damage, handle SIPs by the captive installation screws, the provided handle, ejector levers,
Caution
or the card carrier edges only. Do not touch any of the electrical components or circuitry.
Step 3
Grasp the handle of the SIP with one hand and place your other hand under the card carrier to support the weight of the
card; position the card for insertion into the card cage slot. Avoid touching the SIP printed circuit board, components, or
any connector pins.
Step 4
Carefully slide the SIP into the slot until the ejector levers make contact with 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 SIP until the ejector lever
hooks are fully latched.

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 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. Tighten the locking thumbscrews
on both sides of the SIP to a torque of between 8.3 and 11 inch-pounds (94 to 124 N-cm). Do not overtighten.
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.
