or replacement port adapter. This chapter contains the following sections:

• Handling Port Adapters, page 3-1

Handling Port Adapters

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.

Caution When powering off the router, wait a minimum of 30 seconds before powering it on again.

Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components

or connector pins. (See Figure 3-1.)
