The internal power supply on my 2960 has blown and I need a new one. I've asked the TAC for a part number and they say there isn't such a beast and I should contact my local distributor. The distributor are asking £350 to fix the switch which is excessive. Normally there is a label on the sheet metal case with the manufacturers part number so you can obtain a power supply without the 1000% mark up, but my supply doesn't have one. Does anyone have a 2960 to hand to inspect the manufacturers part number or perhaps you know which power supply is required for the 2960? Thanks in advance.
