Five jumpers are provided for logical drive number assignment. DS1,

select line matches the installed jumper. Jumper G, when installed,
causes the drive to be selected constantly. The Quantum part number
for the jumper plug is 22-10036.

Control Cable Termination
-------------------------
If the Model Q500 is the last drive at the end of the control signal
cable, a 220/330 ohm terminator pack must be installed at PCB
location RN3. The terminator must be removed from RN3 is the drive is
not at the end of a string of drives. The Quantum part number for the
terminator pack is 13-12302.
