Feature Overview

With the Cisco 7300 Series Power-On Diagnostics feature you can configure your Cisco 7300 series router to run diagnostic tests on the installed network services engines (NSEs) installed in your system. Use the diagnostic level power-on command to enable power on diagnostics. The power-on diagnostics run only when the system is in the process of booting from a power on or is rebooting after a system crash. User-initiated system reloads do not initiate power on diagnostics to be performed though the diagnostic level power-on command has been configured.


Note Any failure in the power-on diagnostics results in the boot of the software being aborted.


Table 1 lists possible error messages which may be generated upon reboot when Power-On Diagnostics is enabled.

Benefits

Online diagnostics tests report any hardware failures after booting after a router crash or power cycle.

Restrictions

Enabling Power-On Diagnostics increases bootup time.

Any failure in the power-on diagnostics results in the boot of the software being aborted.

Configuration Tasks

See the following section for the configuration task for the Cisco 7300 Series Power-On Diagnostics feature.

Configuring Power-On Diagnostics (required)

Configuring Power-On Diagnostics

To configure Cisco 7300 Series Power-On Diagnostics, use the following command in global configuration mode:

Command
Purpose

Router(config)# diagnostic level power-on

Enables online diagnostic background tests on the system hardware. Online diagnostic tests report any hardware failures after booting after a router crash or power cycle. Enabling this command increases boot time.

Troubleshooting Tips

When you configure the diagnostic level power-on command, the following output should be displayed as the system is booting after a power cycle or router crash:

Command Reference

This section documents the new command introduced by this feature. All other commands used with this feature are documented in the Cisco IOS Release 12.1 command reference publications, and in the document Cisco 7304 Series Platform-Specific Commands.

diagnostic level

diagnostic level

To turn on power-on diagnostic tests for the network service engines (NSEs) installed in a Cisco 7300 series router, use the diagnostic level command in privileged EXEC configuration mode. There is no no form of this command.

diagnostic level {power-on | bypass}

Syntax Description

power-on

Power-on diagnostic tests are performed at system bootup on the NSEs.

bypass

No diagnostic tests are performed. This is the default.


Defaults

No diagnostic tests are performed.

Command Modes

12.1(10)EX2

This command was introduced.

12.2(18)S

This command was introduced on Cisco 7304 routers running Cisco IOS Release 12.2 S.


Usage Guidelines

Use this command to enable power-on diagnostic tests to run on the installed NSEs of a Cisco 7300 series router when the system is booted. It is recommended that you issue this command only if you are experiencing problems with an NSE and are planning on rebooting the router. Issuing this command causes an increase in the boot time.

Examples

The following example shows how to enable diagnostic power-on tests:

diagnostic level power-on

The following sample output shows the output that is displayed upon system bootup after a power cycle or router crash:
