8.1.1
Notes for Figures 7a, 7b, 7c, 7d and 7e.
[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" and "WC" 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.
[3]
Reserved useage. Do not install any jumpers.
[4]
Table 4 summarizes the configuration selection possibilities available on the different Hawk 2XL model
drives
[5]
These signals are also on 80 pin J1 (see Table 11c)..

("X" means the function selection can be made with jumpers on that connector;
("Y" means the signal is available to host through that connector.)
Note.
[ ] for Table 4:
[1]
Use either J6 or J1-Aux, but not both.
[2]
I/O connector J1 plugs directly into host. No jumper can be installed on J1. The host supplies the logic
state of these function signals; causing the selection of these functions. See pinout Table 11c.
[3]
The host can drive a remotely located Drive Activity LED using signal.
[4]
Use either J1 or J6, but not both.
[5]
The drive reads the ID (asserted low) from J1-Auxiliary pins 1, 3, 5 and 7 for 250 ms after power-on or
drive reset. Jumper plugs can be used on J1-Auxiliary pins 1-2, 3-4, 5-6 and 7-8 to set drive ID if desired,
but usually a connector/cable is plugged to J1-Auxiliary to run these signals to the host for remote ID
selection.
[6]
The drive ID signals in the 80 pin J1 connector are asserted low by the host for 250 msec after power-on
or drive reset.
