SG terminal

The HDD is not provided with an SG terminal (fasten tab) for DC grounding. Therefore, when
connecting SG and FG in the system, use the +5 VDC RETURN (ground) inside the power supply
connector as the SG on the power supply side.

Connector for external operator panel

• Connector for 16-bit SCSI external operator panel

CN1 provides connector for the external operator panel other than the SCSI bus as shown in
Figure 4.18. Also, a connector for the external operator panel are provided on the HDD as
shown in Figure 4.19. This allows connection of an external LED on the front panel, and an
SCSI ID setting switch. For the recommended circuit of the external operator panel, see
Subsection 4.3.4.
