Removing and Installing a SIP, page 4-2
Handling SIPs
Each SIP 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 Shared Port Adapter or a SPA
for a list of parts and tools required for installation.
Caution
Always handle the SIP by the carrier edges and handle; never touch the SIP components or connector
pins. (See
.)
When a slot is not in use, a blank must fill the empty slot to allow the router to conform to
electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the
installed modules. If you plan to install an SIP in a slot that is not in use, you must first remove the blank.
