	Y	Load the FLASH boot release, with no patch, and skip straight to step 6.
	S	Start with the default configuration. Any boot script or NVS
		configuration is ignored.
	N	Configure from NVS, ignoring any boot script.
	[Ctrl/D]	Enter diagnostics mode.

When you start the switch the FLASH boot release is always loaded first. The FLASH boot release contains all the code required to obtain and check the INSTALL information. This first boot is known as the INSTALL boot. The INSTALL information is inspected and the switch is setup to perform another load. Even if the actual release required is the FLASH boot release, another load is always performed. At this point, if a patch load is required, it is also performed.

The switch startup occurs immediately after the install override option, or after the INSTALL information check. The INSTALL information check performs a full startup of switch software and initiates the normal operation of the switch.

Finally, if there is a defined boot script, this script is executed.

How to Avoid Problems

If you perform the following procedures you may help reduce the likelihood and impact of some future switch events.

Set system territory

Set the system territory to the country or region in which the switch is connected to the network. Some protocols are implemented in differently in some countries. To ensure that the switch uses variants that will work in the country your switch is routing in, enter the command:

SET SYSTEM TERRITORY={AUSTRALIACHINAEUROPEJAPANKOREA

NEWZEALANDUSA}

Backup software files

Store a backup of the current switch software. If the switch software is accidentally cleared from the router’s FLASH memory, you will need to reload the software release and patch files. If your access to the Internet is via the switch, then you will need the files on your LAN. You may wish to keep a copy of the current software and patch files on a TFTP server on your network. You can download switch software from the support site at http://www.alliedtelesyn.co.nz/support/ar400.

Backup configuration script

Store a backup of the latest configuration script, in case the configuration file on the switch is accidentally deleted or damaged.
