Sorry for the silly question but it wouldn't be so silly if i go and unplug the system if it all goes pear shaped! I've got to move a Norstar BCM400 & Norstar business manager 1000E a couple of feet. The leads are all long enough but the system is plugged into a BT UPS. Before i pull the plug is there anything i should know? I assume the UPS is just there so the sytem carries on working in the event of a power cut? (and doesn't mean it will loose data if i unplug it all!) The system shouldn't be off for more than an hour of so. Am i safe to pull the plug?!! thanks.
