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 Chapter 4, “Preparing to Install a Carrier Card 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 6-1.)

When a slot is not in use, a 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 blank filler plate.
