Handling SPAs
CHAPTER
5
Each SPA circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD)
damage. Before you begin installation, read “Preparing to Install a SPA Interface Processor or a Shared
Port Adapter” for a list of parts and tools required for installation.
Caution Always handle the SPA by the carrier edges and handle; never touch the SPA components or connector
pins. (See Figure 5-1.)
When a slot is not in use, a SPA blank filler plate must fill the empty slot to allow the router or switch
to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow
across the installed modules. If you plan to install a SPA in a slot that is not in use, you must first remove
the SPA blank filler plate.

Warning
When performing the following procedures, wear a grounding wriststraptoavoidESDdamagetothe
SPA. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the
midplane or backplane with your hand or any metal tool, or you could shock yourself.
Installing a SPA in a SIP
To install a SPA in a SIP, refer to Figure 5-2 and do the following:
Step 1 To insert the SPA in the SIP, locate the guide rails inside the SIP that hold the SPA in place. They are at
the top left and top right of the SPA slot and are recessed about an inch, as shown in C of Figure 5-2.
Step 2 Carefully slide the SPA all the way in the SIP until the SPA is firmlyseatedintheSPAinterfaceconnector.
When fully seated, the SPA might be slightly behind the SIP faceplate.
Step 3 After the SPA is properly seated, turn the SPA lock to its locked and horizontal position, as shown in A
of Figure 5-2.
Removing a SPA from a SIP
To remove a SPA from a SIP, refer to Figure 5-2 and do the following:
Step 1 If attached, remove any cables from the SPA.
Step 2 To remove the SPA from the SIP, turn the SPA lock from its locked and horizontal position shown in A
of Figure 5-2 to its unlocked and vertical position shown in B of Figure 5-2.
Step 3 Grasp the handle of the SPA and pull the SPA from the SIP. (Ensure that you have already disconnected
the cables from the SPA before removing the SPA from the SIP).

Online Insertion and Removal
Cisco 12000 series router SIPs and SPAs support online insertion and removal (OIR). SPAs can be
inserted or removed independently from the SIP. OIR of a SIP with installed SPAs is also supported.
Optical Device Installation and Removal
Any contamination of the fiber connection can cause failure of the component or failure of the whole
system. A particle that partially or completely blocks the core generates strong back reflections, which
can cause instability in the laser system. Inspection, cleaning, and reinspection are critical steps to take
before making fiber-optic connections.
