The appliance is dead.  It should still be covered under warranty.

Hello Sr,

It is possible that we may a faulty appliance nevertheless try the next action plan:


1- Change the config register to 0x2102
   --Check the settings
   rommon>set

   --Clear the current boot variable
   rommon>unset boot

   rommon>confreg 0x2102

   rommon>reset

If does not fix the issue follow step 2:

2- Connect the management port to access a tftp server.
  
   You will see a message that a physical link is established

   --Issue the set interface gi1 or fa1

   --rommon>set interface fa1 x.x.x.x 255.255.255.0

   DG to use to get to the TFTP server

   --rommon>set ip route default x.x.x.x  

3- Check that the configs which have been made and test connectivity

   rommon>set
   rommon>ping x.x.x.x

4- Once the ping to the tftp is successful, you can issue the boot tftp to specify the image:

   rommon>boot tftp://x.x.x.x/

If the switch comes up we need to copy the image onto the bootflash and change the boot variable again and wr

RMA will the last option if no luck.
