This feature was introduced on Cisco 7304 routers running Cisco IOS Release 12.2 S.
This document describes the Cisco 7300 Series Power-On Diagnostics feature and contains the following sections:
•
Supported Standards, MIBs, and RFCs
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.

Configuring Power-On Diagnostics Example
The following example shows how to enable power-on diagnostic tests for the NSEs installed in a Cisco 7300 series router:

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
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
Privileged EXEC
Command History
Release Modification12.1(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-onThe following sample output shows the output that is displayed upon system bootup after a power cycle or router crash:

Note
This output is displayed when the system is booting, not when the command is issued.
