A-10 Technical Specifications
A.2.3 The SCSI Busy LED
The SCSI Activity LED interface on the LSIU160 is a four-wire
arrangement that allows the user to connect an LED harness to the
board. The buffered GPIO0_FETCH line (maximum output low voltage
0.4 V and minimum output low current 16 mA) is pulled low to complete
the circuit when a harness with an LED is attached. The SCSI Busy LED
connector is J6. The signal definitions for the SCSI Busy LED connector
are provided in
Table A.6 .
A.3 Subsystem and Subsystem Vendor ID
The Subsystem ID and System Vendor ID for the LSIU160 are provided
in
Table A.7 . The ID numbers are contained within the EEPROM of the
LSIU160. During system initialization, the ID numbers are loaded into the
Subsystem Vendor ID and Subsystem ID registers of the LSIU160 SCSI
Controller (the LSI53C1010). For more information on the operation of
the Subsystem Vendor ID and Subsystem ID registers, refer to the
LSI53C1010 PCI to Dual Channel Ultra3 SCSI Multifunction Controller
Technical Manual.
