Putty to MSA 1040 gives sh: write error: No space left on device

Hi,

I'm trying to Putty into an MSA 1040 but it gives "sh: write error: No space left on device" and puts me back to the logon. I know the logon is correct as if I do it wrong it says "Login incorrect"

I'm attaching from a 2012 VM server using USB passthrough from an ESX host, I have the MSA driver installed on com3 and it works in another site fine. I also tried from 2008 server and get the same error in putty.

Any ideas?
I need to get in to be able to set the IP adress of the iLO up. It's currently displaying an IP of 10.0.0.2 which I can't get to.
