[4] The drive time-shares the ID and BUSY LED/SSP
functions of J6 and J1-auxiliary. That is, a cable may be
attached to one of these headers to pick up the synchro-
nized spindle reference signal (SSP) and signal that
lights the external BUSY LED indicator. If lines for
external ID selection are not also included in the cable,
jumper plugs must be used on the header not having a
cable connected in order to establish drive ID. The drive
reads the ID from J6 and J1-auxiliary for 250 ms after
power-on or drive reset, and then uses these headers
for the LED and SSP functions the remainder of the
time.
[5] "W" models only.
[6] "W/WD" models only.
[7] "WC" models only. Use the ID signals from the host in
J1, or jumpers on J6 to establish drive ID, but not both.
