Handling SPAs
Each SPA is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. Before
you begin installation, read
Chapter 4, “Preparing to Install a SIP or a SPA,” 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 6-1).
When a subslot 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.
