Help!!! - Erase Flash error! 3750 Catalyst Switch

Unanswered Question

Hi,


In my error I ran a 'erase flash' and deleted the entire flash rather than a file within the flash. Now the switch boots into a 'switch:' mode with limited options. Is there a way of copying across a flash. Xmodem doesnt seem an option?

Thanks

Hello,


can you try the 'flash_init' command first ?

Have a look at the document below (it is not specifically for the 3750, but I think the procedure is the same):


Recovering Catalyst 2950, 2955, and 3550 Series Switches from a Corrupted or Missing Image

Hi


In additions to leos comments would like to know the issues in using the Xmodem option available out there.

i have seen uploading ios using Xmodem into the 3750 switches only the .bin files ,if possible can u also try that and chck it up how it goes..


once u r thru with that you mite want to check this link to get on the whole bundle onto ur flash system..

Hi,


Thanks, it worked!!!! - I used the copy xmodem command and it took around 2 hours to copy the file. Then used the boot flash:(file name) and it works all ok. cheers
