1. Can someone help how to recover from this?

2. Service contract for this switch is expired.

Hi,

 

I'm no JTAC engineer but this looks looks like a ROM read error.

Did you try to update JunOS before this happened? Looks like a install error onto the ROM if you did or if not potentially the ROM's failed?

 

When it boots up do you get to the point of selecting the boot media and try a reinstall JunOS?

 

Little more JTAC issue here but without a support warranty yeah i can see why you're stuck.

Hi schittar@uk.ibm.com,

 

 As per the symptoms, this may be a hardware issue. Still you can try recovering the switch using the format install process as long as you see this prompt:

 Hit [Enter] to boot immediately, or space bar for command prompt.

 Otherwise, you may try contacting Ccare for options to renew the contract.

 

Best regards,

Esteban!

No. I did not attempt to upgrade any JunOS. I suspect there was a power failure to the rack. I can't get to the point where I can press Enter.

I can't get to any prompt. I guess I have to wait till the contract is renewed and get the switch replaced.

Hi there,

 

have you tried a recovery on the device? (you need a usb)

Performing a Recovery Installation
http://www.juniper.net/techpubs/en_US/junos15.1/topics/task/installation/junos-software-reinstallati...

 

that is the last thing you can try otherwise as the thread suggests you need to replace it 

 

 

I help you, you help me... please share a Kudos or accepted solution whenever you feel I have helped with your problem! Smiley Happy

Have you tried to format install the device?
It could really help in case of recoverable hardware storage issue.
 
Thanks,
Deimos.

Hi schittar@uk.ibm.com, 

 

It look like won't let you get into linux recovery mode, could you share full output during initial boot? you might want to try format install if the system allows you to do, if not you might need to ask for replacement.

 

btw , has this been resolved?
