stack compatibility with WS-C3750X-12S

[ippolito]

Hi,

Can a WS-C3750X-12S coexist in an existing stack made up of a WS-C3750G-12S and a WS-C3750G-24TS?

thanks

Mike

Yes

Sorry Edison, I'm really sorry but I'll disagree with you on this ...

3750X-12S will not be compatible with the 3750G-12S because the latter (3750G-12S) only has 16 mb of flash.

The 3750X-12S is supported starting from IOS version 12.2(58)SE1.  This version isn't supported with 3750/3750G models with 16mb of flash because the BIN file alone is >16mb.

If your other 3750G-24TS has 16mb of flash, then my answer is still the same.

No need to be sorry - great response and rated!

Thanks Edison.

Thanks for the answer, that explains much.  I don't suppose you can buy flash memory to upgrade a 3750 that shipped from the factory with only 16 mb?

thanks

Mike,

That is correct.  The flash card is not upgradeable for these switches.
