I pulled this switch off the shelf and wanted to use it but after consoling in realized their is no IOS installed on the flash.  So I started a TFTP server on the laptop, consoled into the switch and mapped it to the IOS I downloaded from www.cisco.com ( c3750-ipservicesk9-mz.150-2.SE.bin ) I typed in the command:
switch:copy tftp flash
   and it replied with :
tftp: no such device

How do I load the IOS onto this switch?

From the privileged prompt:

Switch# copy tftp: flash:

If you are in 'rommon>' mode, the process is different.

It doesn't have an IOS intalled right now so I don't get a priveleged prompt, just

switch:

However the link that you posted said to go into xmodem in hyper terminal and send it through there and had it all step by step.   Here they are:

copy xmodem:c3750-ipservicesk9-mz150-2.se.bin
then go to hyperterminal, transfer and send the file with xmodem

It is sending the file to the switch right now.  Great link lets see what happens.

Remember to change the config register to 0x2102
Otherwise the switch will continue to boot into rom monitor mode

All the best

I tried to access the rommon mode but was not able to.  I was not able to find the confreg or config register command in either mode, ios/boot loader.  The switch is taking a very long time to boot after reloading I believe it is because I can not change the config register to 0X2102.
