Maintaining and Upgrading the Router 5-1

Maintaining and Upgrading the Router

5

This chapter contains information on procedures you may need to perform as your internetworking
needs change.

Note

If your system requires an upgrade in the future, and if new network processor modules or

software replacements are necessary, an appropriate publication will be shipped to you with the parts.
The publications that ship with spares and upgrades, configuration notes, do not need to be ordered
separately from the new components.

This chapter contains the following sections:

•

Accessing the Router Internal Components

•

Removing Network Processor Modules

•

Memory Replacement Procedures

•

Replacing Network Processor Modules

•

Replacing the Component Tray

•

Testing Your Installation

Caution

Before opening the router chassis, ensure that you have discharged all static electricity

from your body and be sure the power is OFF. Before performing any procedures described in this
chapter, review the following sections “Safety Recommendations,” “General Site Requirements,”
“Installation Checklist,” and “Required Tools and Equipment” in the chapter “Preparing for
Installation.“

Accessing the Router Internal Components

You must open the router chassis to gain access to the router’s internal components: the network
processor modules, boot ROMs, and jumpers.

Refer to the section “Required Tools and Equipment” in the chapter “Preparing for Installation” for
the tools needed for the following procedures.
