No IOS, Switch boots up with Switch:

Unanswered Question
May 14th, 2008

I've recently got my hands on another 2900 XL switch for my lab at home but it doesn't seem to have an IOS installed. My plan is to load the IOS from my other 2900 XL Switch and on to this one... I have the bin (IOS) file on my PC and i'm connected to the Switch with no IOS via a console port.

The Switch as it stands is sat at

Switch: its like its in ROMMON mode, not sure. Can anyone advise which areas i shoud start to look in to get this IOS insalled. It seems the documents i have been reading talk about updating the IOS from the IOS, but in my case i dont have an IOS installed... :-(

Any advice would be great!

Checkout if this option is available from rommon.

Rommon > Set IP_ADDRESS=x.x.x.x

Rommon > Set IP_SUBNET_MASK=

Rommon > Set DEFAULT_GATEWAY=x.x.x.y

Rommon > Set TFTP_SERVER=abcd

Rommon > Set TFTP_FILE=ios_image.bin

Rommon > tftpdnld

Or the other method is xmodem, but that process takes too long.
