Restricted Maintenance Procedures

This section contains procedures that should only be performed by authorised service personnel. Unauthorised use of procedures in this section may cause danger of injury from electric shock, damage to the router, and invalidation of the product warranty.

If you would like to know more about the procedures outlined in this section, please contact your authorised Allied Telesis distributor or reseller.

Diagnostics

The router software includes a set of diagnostic programs. These programs perform basic level checks of all system components. They do not run in conjunction with the normal operating code, and require that the system be totally dedicated to their use. A detailed knowledge of the way your router hardware functions is necessary if diagnostics are to be used effectively.

!Caution Diagnostic mode is only to be used by authorised service personnel. Unauthorised use of diagnostic mode may cause the router to cease functioning.

The router will not function as a router if diagnostic mode is running.

AR026 PIC The diagnostics programs do not perform checks on AT-AR026

PICs.

To enable diagnostics mode:

1.Connect a terminal to the console port.

Connect a terminal to the console port (port 0) on the router’s rear panel, and set the terminal communications parameters to:

•9600 bps

•8 data bits

•1 stop bit

•No parity

•Hardware flow control

2.Restart the router.

Restart the router, either by switching it off and on again using the power switch on the rear panel, or by using the terminal to login and enter the command:

restart reboot
