General Description 113
The HSG80 Array Controller components that you will use most often,
such as the maintenance port and the OCP, are conveniently located on
the controllers front panel. The host port and program-card slot are
also located on the front panel, making it easy to update the controllers
software or to connect the controller to a different host.
Each controller is supported by its own cache module. Figure 14
shows which cache module supports which controller in a dual-
redundant configuration in a BA370 rack-mountable enclosure.
Figure 17 Location of Controllers and Cache Modules
Tip DIGITAL recommends that you use the slots for controller A and
cache module A for single configurations. Slot A responds to SCSI target
ID number 7 on device buses; slot B responds to SCSI target ID number
6 on the device buses.
Operator Control Panel
The operator control panel (OCP) contains a reset button and six port
LED buttons, as shown in Figure 15. The reset button flashes about
once per second to indicate that the controller is operating normally.
The port button LEDs correspond to the controllers device ports and
remain off during normal operation. If an error occurs, the reset button
and LEDs will illuminate in a solid or flashing pattern to help you
diagnose the problem. See Appendix C, LED Codes, for further
explanation on these codes.
