An Enterasys B2H124-48 switch has an error message and does not boot

[Renan]

The switch B2H124-48 does not boot and shows the following message:

Computing MD5 Checksum of operational code...
Operational code CRC is invalid.
Boot Menu Version 01.00.48 10-21-2010

I think I can upload the firmware file via XMODEM to the switch, but I can not find the firmware file.
Where can I find the firmware file for this switch?

hi, my switch froze after trying to read the flash in the card reader, or coincidentally, the console displays a memory test and that’s it, whether the flash card is involved in starting the switch or not, thanks for the answer, and did you find the firmware, do you have it? old firmware.

The B2 is end-of-service for (i think) more than 5 years now.

You can’t download the firmware anymore in official sources.

Thanks for the answer. Who can share the firmware, how to fix the flash drive, can you provide the firmware?
