Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge
(ESD) damage.
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router or
Note
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.
Caution
Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components
or connector pins. (See
