Operating the UltraSCSI Enclosure
UltraSCSI RAID Enclosure 2–7
Starting the Subsystem
After installing the departmental server cabinet or data center cabinet and
connecting the enclosures, you can apply power to start the subsystem.
Applying power to all the enclosures causes the EMU, PVA, and array
controller to automatically begin system operation.
_____________________ Note ______________________
Before applying power to the subsystem, be sure to configure
the entire subsystem, to include the host and the array
controller, as described in the appropriate publications.
________________________________________________
Initial power application is simply a matter turning on the ac power
controllers located in the lower left and right corners of the enclosure (see
Figure 2–2). Pressing
1
on the ac power switch applies ac power only to the
shelf power supplies on the associated power bus (bus A or B). Apply power
in the following sequence:
1. All expansion enclosures.
2. Master enclosure.
