There are different jumper settings on the two drives.
You should compare them and replace the ones from the working lower one 
by the settings of the defective upper one before switching them.
Also you'll have to remove the terminator resistor pack of the upper 
drive drive and plug it into the lower drive before switching the 
interface cables.
Typical jumper differences are the DS (drive select), which should be 
DS0 or DS1 for the upper drive and DS 1 or DS2 for the lower drive 
(numbering starts either with 0 or 1, check the prints on the drive)
Also there might be a difference with the MM/SM jumpers.
