Installing and Removing a Carrier Card

This chapter describes how to install or remove carrier cards on the Cisco 7304 router. This chapter

contains the following sections:

• Handling MSCs, page 5-1

• Online Insertion and Removal, page 5-2

• MSC Installation and Removal, page 5-3

Handling MSCs

Each MSC circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD)

damage. Before you begin installation, read Chapter 4, “Preparing to Install a Modular Services Card or

a Shared Port Adapter,” for a list of parts and tools required for installation.

When a slot is not in use, a blank module filler plate 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 installed modules. If you plan to install an MSC in a slot that is not in use, you must first

remove the blank module filler plate.

Caution Always handle the MSC by the carrier edges and handle; never touch the MSC components or connector

pins. (See Figure 5-1.)

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