I hope someone can help me. this is the case:

I have a Juniper srx-100-b and I tried to configure this device completely from scratch. What I have done, in u-boot mode, I perform the command 'erase all' (twice). Now i'm lost the partitions on the device, so the device can not load JunOS.

When I connect with the console cable, I don't see any post messages.

My questions is: Is there a way to recover these partitions and install JunOS on a complete empty device.

Thank you in advance.

The correct procedure for this would be to run request system zeroize from the cli.

Does the device still boot to U-boot when you restart it? If so maybe you can follow this procedure to re-install junos.

  • No the device doesn't boot to u-boot that is the whole problem. When I connect with the console cable, I don't see any output.

    I've just entered U-boot to check on the command that you used and it mentions this: erase all - erase all FLASH banks I think you bricked the device and at this point only Juniper could help you.

  • @xpto is correct, Juniper will issue you an RMA under a valid warranty. If you haven't created a JTAC case, you should. Feb 5, 2016 at 14:26

The correct process for beginning with a blank configuration is:

user@hostname# delete
user@hostname# set system root-authentication plain-text-password
user@hostname# commit
user@hostname> request system reboot


request system zeroize

Will give you a default configuration if you read here: http://www.juniper.net/techpubs/en_US/junos15.1/topics/reference/command-summary/request-system-zeroize.html
