Removing and Installing Port Adapters
This chapter describes how to remove the PA-VXA, PA-VXB, and PA-VXC port adapters from
supported platforms and also how to install a new or replacement port adapter. This chapter contains the
following sections:
•

•
•
Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge
(ESD) damage.
Note
When a port adapter slot is not in use, a blank port adapter 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 port adapters. If you plan to install a new port adapter in a slot that is not
in use, you must first remove the blank port adapter.
When powering off the router, wait a minimum of 30 seconds before powering it on again.
