Installation
Maxtor Atlas 10K III 3-13
Configure the desired spin up option (Table 3-3) by setting the state of the
DELAY_SPIN (Pin 38) and STAGGER_SPIN (Pin 78) inputs on the 80-pin SCA-
2 connector (Figure 3-5). The states of these signals are set by using either hard-
wired connections at the backplane or backplane logic.
Spin Up on Power On Options
The drive provides the output BUSY_OUT signal to power a user-supplied activity
LED.
The output indic ates the drive is perf orming a SCSI operati on. To use thi s outpu t,
connect a user-supplied LED cathode to the BUSY_OUT connection, pin 77 on
the SCA Connector (Fig ur e 3-5) . The LED anode must be attached t o the pr oper
+5 VDC supply through an appropriate current-limiting resistor.
