Hawk 2 (Wide bus) Family Install Guide, Rev. C 29
[4]The drive time-shares the ID and LED/SSP functions of J6 and J1-auxiliary. That is, a cable may be attached to one of these headers to pick up the synchronized spindle reference signal (SSP) and three signals that light external LED indicators. 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. Host system documentation should describe the application of the three LED indicators if it connects a cable to use this option.
