8.1.1 Notes for Figures 8, 9, 10 and 11.
[1] Notes explaining the functions of the various jumpers on jumper header connectors J2, J1-Auxiliary and
J6 are given here and in Section 8.1.2. The term “default” means as standard OEM units are configured
with a jumper on those positions when shipped from factory. “Off” means no jumper is installed; “On”
means a jumper is installed. OFF or ON underlined is factory default condition.
[2] The PCB on “N” model drives does not have connector J1-Auxiliary. The J1-Auxiliary connector signals
conform to SFF-8009 Revision 2.0, Unitized Connector for Cabled Drives, signal assignments for auxiliary
connectors. See note [4].
[3] Reserved useage. Do not install any jumpers.
[4] Table 4 summarizes the configuration selection possibilities available on the different Hawk 4XL model
drives.
[5] Voltage supplied by the drive.
[6] J1A Drive Activity LED—with series resistor built-in pin 12, is the open collector driver that drives the
external LED minus side low to turn it on. This output is capable of driving > 20mA. This is the same signal
as on J6 pin 12, except J1A pin 8 goes through a 220 Ohm resistor. Tie the minus side of the external LED
to this pin.
[7] J6 Drive Activity LED—without series resistor built-in pin 8, is the open collector driver that drives the
external LED minus side low to turn it on. This output is capable of driving > 20mA. This is the same signal
as on J1A pin 8, except J6 pin 12 does not go through a 220 Ohm resistor. Tie the minus side of the exter-
nal LED to this pin.

Caution:
Do not use J2 jumper
plugs on J6 or J1-
Auxiliary, as the internal
contacts will be deformed
and can not be used on
J2 without them falling off.
