Cisco - 3750

Somehow on rebooting a 3750 it seems to have lost it's image. It is part of a 3 3750 switch stack. There is one master already booted in the stack. I don't see any commands in the switch: mode that allow me to tftp load an image or boot an image over the network. Curious about how it lost it's image in the first place but more interested in getting one back on there. Any ideas?

The system is unable to boot automatically. The BOOT

The best way here.. is to download the IOS from one of the other 3750's then break into rommon on the one needing the upload, and upload the image there.someone must have erased the flash..

but how do i download the image? do I need to break into rommon mode on boot and it will allow me to tftp?
I thought i'd read that it should download an image automatically from the master - of course, the other switches have no config so I don't know if that's applicable.

You would need to login to a good switch, then TFTP the IOS down.. you do not need to be in rommon mode on the good switchs. If you need help with this, login to the www.cisco.com website and do a search for your switch model / and you should be able to find the commands to TFTP download and upload.

If you can not telnet into one of the working switches to download the IOS, then you will need a CCO login to be able to download from cisco's website.the receiving unit you can console it up, will take a bit ( avg 1 - 1/2 hr ), but it can be done. Cisco's website has the commands that you will need. If you are unsure, it might be best for you to pay for a tech to come out and do this for you.
