I need a little assistance, with the power supply, the inlet, C-14, IEC 60320 that fits on the rear of the MX2424, that has power cable inserted into it. What is the correct model for the MX 2424, also, what is the price range for one? Where can I find one? The cable is C-13 is the cord, (cable). I have a photo of the rear of the mx2424, but can't upload, I don't have permission is the reason.
