Notes for Figures 14, 15, and 16.

[1] Notes explaining the functions of the various jumpers on jumper header connectors J2, J5, and J6 are
provided in Section 8.1.2. The term "default" indicates how standard OEM units are configured when
shipped from factory. "Off" means the jumper is not installed; "On" means a jumper is installed. OFF or ON
underlined indicates the factory default condition.
The PCBA on LC models does not have connector J5. The J5 connector signals conform to SFF-8009
Revision 2.0, Unitized Connector for Cabled Drives, signal assignments for auxiliary connectors.
[2] These signals are also on the 80-pin J1 I/O connector. See Tables 18 and 19.
[3] Voltage supplied by the drive.
[4] Dashed area is optional host circuitry (external to the drive) connected to host-supplied optional usage
plug.
[5] Do not connect anything to J5 pins 9, 11-12, or J6 pins 13-20.
[6] Connect an external Drive Activity LED to J6 pins 11 and 12, or to J5 pin 8 and the drive's +5V power
source, through an appropriately-sized current-limiting resistor. The drive provides an internal 150 ohm
current-limiting resistor for the J6 connection.
