4.4 HS Array Controller LEDs and Fault Notification
The operator control panel (OCP), normal operation, and fault notification are
discussed using a typical HSZ40 controller for reference.
4.4.1 HSZ40 Operator Control Panel
The HS controller OCP contains the following:
• One reset button (//) with an embedded green LED
• One button per SCSI port
• Six amber LEDs

Figure 4–3 shows the HSZ40 controller OCP. Buttons and LEDs serve different
functions with respect to controlling the SCSI ports and/or reporting fault and
normal conditions. Button and LED functions are discussed in the following
sections.

4.4.2 HSZ40 Normal Operation
The reset (green) LED (//) reflects the state of the controller and the host
interface. Once controller initialization completes and its firmware is functioning,
the green button constantly flashes. Pressing the green button during this normal
operation resets the controller.

The HSJ-series controller has the amber LEDs embedded in the port buttons.
