Removing and Installing Port Adapters

This chapter describes how to remove the PA-T3+ port adapter from supported platforms and also how

to install a new or replacement port adapter. This chapter contains the following sections:

• Handling Port Adapters, page 3-1

• Online Insertion and Removal, page 3-2

• Warnings and Cautions, page 3-3

• Port Adapter Removal and Installation, page 3-4

• Connecting a Serial Cable, page 3-12

Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge

(ESD) damage.

Note When port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router 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.

Handling Port Adapters

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.)
