8.1.1Notes for Figures 14 through 18

[1]Notes explaining the functions of the various jumpers on jumper header connectors J2, J5, 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.

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 J1 I/O connector (J5, Pins 1-12). See Figure 12.

[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 and 12 or J6 pins 13-20.

[6]Connect an external Drive Activity LED to J6 pins 11 and 12 (see figures 10 and 11), or to J5 pin 8 (see Figure 12) and the drives +5V power source, through an appropriately sized current limiting resistor. The drive provides an internal 150 ohm current limiting resistor for the J6 connection.
