Powering Off D-brick2
Before powering off the D-brick2, confirm that the following has occurred:
•
All system users have been notified and are logged off.
•
Disk data has been backed up as appropriate.
To power off a D-brick2 enclosure, follow these steps:
1.
Move the power switch on the rear of each PSU/cooling module to the “off”
position (position
I
= on,
O
= off). The location of the power switch on the D-brick2
PSU/cooling module is shown in Figure 1-24.

2. Unplug the power cable from the PSU/cooling module(s) as appropriate. For
example, you would follow this step when you are replacing a module.
3. If you are shutting down all of the D-brick2s in a rack, you may want to move the
PDU breaker switch to the “off” position.
The LEDs on the back of the unit should turn dark a few seconds after you power off the
PSU/cooling module.
