Changing other applicable jumper options
Barracuda 2, 2HP drives are designed for use in a variety
of systems. Unique installations may require you to
change one or more of the other jumpers to meet specific
system requirements; however, in most cases, you will
not need to change any of these jumpers for normal drive
operation. Figures 6a and 6b provide the information
necessary to configure all jumpers not discussed else-
where in this manual.
Pin 9 (top pin) is negative (cathode),
Pin 10 (bottom pin) is positive (anode).
Remote LED Connector*
*Note to subsystem designers: In Europe, a red LED indicates 
an error or warning condition. For this reason, you may want to 
use a color other than red with this connection.
