Thanks to all that responded to Andy's plea, on my behalf, for a 2500 series power supply. I've managed to find a supplier in NZ - a list member - and it should be here in a couple of weeks. In the meantime we got the box running per the solution at http://www.hardstaff.com/Computer/Cisco/index.html and it's been working for about a week now with no apparent problems. Cheers, Jon
