The power sequencing jumper is a small round plug with four pins that are 
placed in a contact near the black data cables. I can't quite picture the 
RA81 now, but I think one of the connectors is to the left of the data 
cables and one on to the right of them. They should be labeled "in" and 
"out". The power sequencing forms a chain through the use of power 
sequencing cables such that the first drive in the chain (the one with the 
jumper instead of a cable on "in") starts first, then the next one and so 

The jumper is about 5cm long, 1cm in diamater I think, usually black with 
a silvery threaded ring that holds it in position.
