Introduction

This chapter provides descriptions of possible cable modem gateway

performance and installation issues that may occur after the cable

modem gateway is installed. This chapter also shows specific

examples of the condition as shown by the LED status indicators on

the front panel of the cable modem gateway. These indicators provide

visual feedback so you can troubleshoot the situation quickly.

Audience

This chapter contains detailed troubleshooting instructions for

Customer Support Representatives (CSRs), cable modem gateway

installers, and network support engineers who troubleshoot

performance situations and conditions that occur with the cable

modem gateways.

Important:

For all of the scenarios listed in this chapter, you will have

full access to the WebWizard from the CPE until the cable modem

gateway is registered on the network. The vendor-specific MIB for

controlling access to the WebWizard does not take effect until after the

cable modem gateway registers with the CMTS.
