3750v2-24FS IOS compatibility

Answered Question

Snippet below is from: 

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps5023/product_bulletin_c25-639468.html


Question:  Will IOS c3750-ipbasek9-mz.122-55.SE4.bin boot/load and function correctly on a 3750v2-24FS?


Based on the snippet below, I suspect not.

When I booted up the device, I saw in the startup/boot process that the IOS checked to see if the bootldr had to be upgraded (did not need to be upgraded).  Device shipped with c3750-ipbasek0-mz.122-55.EY.bin


Thank you.

Customers should prepare to upgrade using this migration  path.

Oh nuts.  I did NOT see the "FS"! 


You'll need to run a minimum of 12.2(55)SE5 to be able to get the FS to work.


My sincerest apologies.

With c3750-ipbasek9-mz.122-55.SE4.bin, WS-3750V2-24FS generates a hardware and firmware incompatible message; device endlessly tries to reboot.

Once 12.2(55)SE5.bin or the preloaded EY.bin is restored, WS-3750V2-24FS boots correctly.

Not a problem.  First FS I've had an opportunity to work with and shipped with the latest IOS EY.bin

"EY" IOS????

Thanks for the ratings.

This is a 3750v2-24FS, that is, with the optional SFP modules.


I get an error message stating “Firmware is incompatible with IOS”.


I get the flash_init to load at the ROMMON prompt but not the load_helper.


Thank you.
