8.1.1 Notes for figures 15, 16, 17, 18, and 19
[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 80-pin J1 I/O connector. See tables 17 and 18, note 9.

[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 (see Figure 15), or to J5 pin 8 (see Figure 17)
and the 5V power source, through an appropriately sized current limiting resistor. The drive
provides an internal 150 ohm current limiting resistor for the J6 connection.
