Notes for Figures 11, 12, and 13.

[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 14 and 15.
