Looking at this drive with the power interface facing you and to the left,
there is a 6-pin jumper block on the right. The order of pins (going from
left to right) is 1/2, 3/4, 5/6.

Single drive: Pins 1 and 2 closed, Pins 3 and 4 open.
Master drive in 2 drive system: Pins 1 and 2 closed, Pins 3 and 4 closed.
Slave drive in 2 drive system: Pins 1 and 2 open, Pins 3 and 4 open.
(for slave drive, no connections on pins 1/2 and 3/4 - leave them open)

External LED option disabled: pins 5 and 6 open
External LED option enabled: pins 5 and 6 closed.

Note: to use an external LED, connect the LED to the controller card,
close JB1/pins 5 and 6 and cut loose the LED on the rear of the drive's
circuit board. This is required because the power from the drive is not
enough to power two LED's.

Hi!

I have one of those ST157-A too, and when I bought a WD2340 I didn't configure
neither one of them as a master and a slave. I simlpy put the WD on the end
of the cable and the Seagate on the middle (D drive ==> slave) and I have been
using it ever since (then I had an ISA controller, it failed though with my
new VLB controller)
