Removing the jumper from a jumper pin pair disables its corresponding
function, and installing the jumper enables it.
The recommended jumper for use is AMP Shunts (14227-1), JAE Short
Socket (PS-2SH4-1) or equivalent.
The following table shows the function of each pair of jumper pins.
Notes:
●
The lower row of pins are ground.
●
ID SELECT, PREVENT/ALLOW, and TEST MODE are recognized
only when the power is turned on or SCSI is reset.
●
TEST MODE is reserved for use at the factory only. Do not put a
jumper over TEST MODE pins. Doing so may cause an unexpected
result.
