The RD54's take a lot of POWER. 3. RD54's get HOT.... 4. Given the current ba123 cooling system, and power supplies (dual) DEC only supports three RD53's (or 2 RD54's and one RD53 or ...) and one TK50 per box. 5. personally, I would use two RD54's and the tk50 in the box, and two RD54's in external boxes with external power supplies.... 6. but then again, I can't remember if you can run the signals out from the distribution panel of a ba123...if you can, 5 is the best approach. (doesn't the external boxes require rqdxe's??) -ed cetron cetron@cs.utah.edu
