Problem upgrading new switch in stack

[bharlieatwork]

Hey everyone,

I was wondering if you could help me.  We have a stack of 3 3750's and would like to add another to it.  After hooking up the new switch to the back, it doesn't seem to want to auto update.

Running Show Version:

Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
1 30 WS-C3750X-24 12.2(55)SE1 C3750E-UNIVERSALK9-M
* 2 30 WS-C3750X-24 12.2(55)SE1 C3750E-UNIVERSALK9-M
3 12 WS-C3750G-12S 12.2(55)SE1 C3750-IPBASEK9-M
4 0 WS-C3750G-12S 12.2(55)SE C3750-IPBASEK9-M

Switch 4 is the new switch.  

As I understand it, I can't copy the software version from switch 1 or 2, but thought I would be able to from 3.  I've tried running:

archive copy-sw /destination-system 4 3

But the command does nothing.  No error message, but gives me another command line.

Any ideas?

Thanks to any help you could give.

 - Is there anything in the logs (show logging) after this upgrade-command is given ?

Is auto upgrade enabled? It should be by default

boot auto-copy-sw

Show boot

Does the new switch 4 have enough free flash memory?
Should be some info in the logs as advised by previous poster also.

I don't want to troubleshoot this sort of problem, most especially with a very early IOS version like an "SE1".
The only thing I'd say or recommend is upgrade the IOS of the entire stack.

Thanks for your help everyone, I got it working in the end by deleting the .bin files on the switches and downloading a new one from a ftp server.

Thanks
