CAUTION
Make sure that the trilink connector pins are not bent or damaged before
installing it on the HSD05 array controller.
7. Install a DSSI trilink connector (part number 12–39921–02), shown in
Figure 2–3, at J1 on the front panel of the HSD05 array controller.
8. Connect the DSSI cables to the trilink connector as directed in either of the
the following:
• If the HSD05 array controller occupies one end of the DSSI bus, connect
the DSSI cable to one of the connectors on the trilink. Install a DSSI bus
terminator (part number 12–31281–01) on the other trilink connector.
• If the HSD05 array controller occupies a mid-point of the DSSI bus,
connect the DSSI bus cables from adjacent nodes to the trilink connectors.
The DSSI bus terminator is not used on the trilink in this configuration.
Appendix A shows several typical HSD05 array controller cable
configurations.
9. Restore power to the DSSI bus nodes, but do not boot the host systems at this
time.
2.6 Applying Power
Apply power to the SBB shelf and the HSD05 array controller as follows:
1. Connect the input power cable(s) to the power supply SBB(s) in the shelf.
2. Verify that the Shelf Status indicator on the power supply SBB is lit. If this
indicator is not lit, refer to the StorageWorks documentation to troubleshoot
the cause of the fault.
3. Verify that the following HSD05 array controller indicators (shown in
Figure 2–1), visible from top to bottom through the front panel louvers, are as
follows:
Indicator
Color
Status
DS4
Green
On to show that termination power, supplied by either the
HSD05 array controller or the SBB shelf, is applied to the
SCSI bus
DS3
Green
On to show that termination power, supplied by either the
HSD05 array controller or the host bus, is applied to the
DSSI bus.
DS2
Red
Blinks for 15 seconds during module boot. If this indicator
blinks for longer than 15 seconds, there is a device fault.
DS1
Green
Blinks during normal operation while the subsystem is
booted.
CAUTION
Device unit numbers as seen by the hosts must be unique through
the system or cluster containing the HSD05 array controller. If a unit
number is added that overlaps the unit number of another device on
another controller of a system or cluster, all the devices on the other
