All the interface and power cables connected to the rear of the DAU should be
dressed and tie wrapped. Use special care not to kink or sharply bend the Fibre
Channel cables as they are easily damaged.
Route the cables so that they do not contact the door and guide rails on both
sides of the system rack. Also, ensure that there is some slack on all the cables
and especially the power cord to prevent it from being disconnected from the
DAU when the unit is pulled forward in the rack.
This section describes the sequence of steps for powering the disk array unit on
or off.
Carelessly turning power on or off may cause some data to
be lost, some software to operate incorrectly, or cause
damage to the unit.
Note
: Before turning on the AC power, check for loose
disk modules by ensuring each module is fully seated into
the disk bay.
1. Turn on the disk enclosure connected with the disk array controller (if
applicable), before turning on the disk array unit.
2. Turn on the power switches located on the rear panel of each power supply.
3. Confirm that the POWER LED (green) on the front panel of the DAU is on.
See Figure 1-7. Also check that the POWER LED located on each power
supply on. See Figure 1-9.
4. The disk array unit performs a self-test and initialization immediately after
the power is turned on. When the self-test and initialization complete and
the disk array unit become ready, the READY LEDs (green) on the
controllers in the disk array unit stop flashing and enter the on-state.
Confirm that the controller READY LEDs are on. See Figure 1-10, J4 for
the location of the controller LEDs.
Note
: The disk array unit may take as long as four
minutes (at maximum) to start.
