PRINTENV OUTPUT IS A EXAMPLE THIS VARIOS BEETWEN SOME SWITCH MODELS.

• Hot-to recovery BootLoad in Brocade FOS based Switches.
  

Reboot the switch now, press ESC within 4 Second and Stop a Boot Cycle to enter in boot interface

Select 3 for command shell, here are some command.

Valid commands are:

auto Boot per boot environment variable settings

boot Boot specified image

Identified the Switch ENET_MAC.

• Now we will set Environment Variables, use the command "setenv" to Create a Environment Variable now as below.
  

> setenv AutoLoad=yes

> setenv ENET_MAC=00012345ABCD <- Example ENET_MAC Number, must replace with Switch ENET_MAC

> setenv InitTest=MEM()

> setenv LoadIdentifiers=Fabric Operating System;Fabric Operating System

> setenv OSBooted=MEM()0xF0000000

> setenv OSLoadOptions=quiet;quiet

> setenv OSLoader=MEM()0xF0000000;MEM()0xF0800000

> setenv OSRootPartition=hda1;hda2

> setenv SkipWatchdog=yes

> saveenv

Try printenv to verify is Environment Variables is set now.

Reboot The Switch.

This first Procedure is based on Brocade FOS 4.x and 5.x Switches.

New genearation Switches use U_Boot procedure and is a little Different.
