I have a dead 2620 with a working AC power supply. I also have a 2621 that has a DC power supply. Can I yank the AC power supply from the (dead) 2620 and replace the 2621's DC P/S with no ill effects?
2620 (dead) + AC P/S
2621 + DC P/S
to
2620 (dead) + DC P/S
2621 + AC P/S (usable anywhere, yay!)
I was going to just try it, but decided against potentially blowing it up.
