Hi all,

I'm trying to resurrect a long forgotten X450e. I powered it up with the intention of wiping the config as the credentials & IP are unknown.

I can see the boot sequence through the console and it throws up errors about "linkscan" and then reboots:

I'm guessing this is telling me the switch is looking for a Master in a stack that it was once part of?

This error is stopping me from resetting the config as the switch never fully initialises.

I can get into the bootloader and have tried setting the image to null, but the above error keeps resetting the switch before I get a recovery logon prompt.

I've seen other articles that say updating the firmware through TFTP will fix this, but when I enter the serial number on the support page, I'm told no downloads are available for the switch.

I guess this is because it's out of maint, which is fair enough and I wouldn't expect to have access to the latest version of the firmware, but I would hope I can download the same version the switch is already running.

Any suggestions?

Cheers,

S.

Hi Simon, did you try to boot using the other partition?

In the BootROM menu you can do:

BootROM> boot 1

Then, if the issue persists, try to boot using the other partition:

BootROM> boot 2

Hi Henrique,

yes, I tried both pri and sec configs. Same result I'm afraid.

Kind Regards,

Simon

Hi Simon,

Just want to share "Boot 1" and "Boot 2" options are related to software image and not switch configuration.

Another option would be trying to clear the switch configuration through BootRom using:

BootROM> config none
BootROM> boot

If you have already tried that and the issue still persists, I would recommend you to contact Extreme GTAC for further assistance since this unit might be still in lifetime warranty.

For instructions about how to open a GTAC case, please see the link below:

Hi Henrique,

I'll double check the Boot 1 & Boot 2 options, thanks.

I've definitely tried the "config none" option to no effect.

I'll contact GTAC as you suggest, thanks.

Kind Regards,

Simon

No, not yet. I'm currently jumping through hoops so I can open a GTAC case. I'll update here if the problem gets fixed.

Hi Simon,
 are you able to boot it to login prompt? Could you try to run "REBOOT AS MASTER-CAPABLE" and then run "config none" from BootROM shell again?
 Not sure if it will help but its good to try.

Hi Konstantin,

I'm afraid not. Once the boot sequence hits the errors it triggers a reboot (see my original post), so I never get a login prompt.

Kind Regards,

Simon

Hi Simon,
 I'm not sure if you're already contacted GTAC for troubleshooting but if not just wanted to let you know that we have an article describing the same issue: bcm_linkscan_register issue.

Hi Konstantin,

unfortunately your colleages in GTAC have not been as helpful as you, and have closed the case ( Case#(01236953) ) without offering any assistance.

I've returned the Extreme switch to the junk store room and have used a Cisco device for this particular project.

Thanks for your help.

Kind Regards,

Simon
