Chapter 4 Installing and Removing a SPA Interface Processor
Removing and Installing a SIP
Installing a SIP
A SIP slides into almost any available SIP slot and connects directly to the backplane. If you install a
new SIP, you must first remove the SIP blank from the available slot.
Note
Refer to the installation and configuration guide for your router for information on SIP slot types, slot
width, and slot location.
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 SIP interface cable is long enough for you
to connect the SIP with any external equipment.
Caution
To prevent ESD damage, handle SIPs by the captive installation screws, the provided handle, ejector
levers, 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. (See
Figure 4-3
Ejector Levers
When inserting a card, make
sure that the ejector lever hooks
catch the lip of the card cage.
