Handling SPAs
Each SPA circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD)
damage. Before you begin installation, read the “Preparing to Install a SIP or a Shared Port Adapter,”
chapter 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 subslot 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 subslot that is not in use, you must
first remove the SPA blank filler plate.
