Re-enable management interface via console CLI

Hi all, hoping someone can help!

Very stupidly managed to disable the management interface using the GUI for my Equallogic today, and obviously the management GUI turned red all over and couldn't connect to my SAN.

I can't access the management area using the GUI now to re-enable the interface (as the interface is obviously down now!). 

Is there a command to run using the console CLI connection to re-enable the interface (make it come back up)?

Any urgent help is greatly appreciated!
