My SWR SM-400S has a power connector like you'd find on the back of a PC. I find that the connection is very loose, and if I'm not real careful when I set my rack up, I have no power, or it's intermittent. Is there any way to tighten up this connection (bending the prongs or something)? Advice would be appreciated! --joe
Try using a different IEC power cord. It might be a problem with the connector on the cord more than with the one on the chassis.
