This chapter describes the tasks that should be completed before you connect a Cisco 4000
series router to your network. It contains the following sections:
• Accessing the Internal Components of the Router
• Replacing Network Processor Modules

Accessing the Internal Components of the Router
You must open the 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 to Install
Cisco 4000 Series Routers” for the tools needed to complete the procedures in this chapter.
Warning Before opening the chassis, disconnect the telephone-network cables to avoid
contact with telephone-network voltages. (To see translated versions of this warning, refer

Warning Do not work on the system or connect or disconnect cables during periods of
lightning activity. (To see translated versions of this warning, refer to the appendix
