Removing a Port Adapter
Note
you do not have to power down the router when removing and replacing a PA-E3.
When a port adapter slot is not in use, blank port adapters must fill empty slots to allow the router to
conform to 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.
