• DC turned on when AC is applied to the cells in this partition
• Restore DC to its state prior to AC loss
3. Click Submit .
The power restore policy setting is updated.
Staggering Automatic Booting
You can stagger automatic booting by delaying the number of seconds that DC power is
restored to each partition. This is helpful in controlling the powering up of partitions when
• The system has more than one partition.
• The data center has more than one system.
To stagger automatic booting
1. Log on to the remote console interface for each partition separately and navigate to
the settings page.
2. Select the number of seconds of delay in the Power section of each partition
settings page, as described in 3.5.9 Power Settings .
6.5. System Power-On Self Tests (POST)
Service Processors and host processors (that is, BIOS) run system power-on self tests
(POST) at the following times:
• When AC power is turned on and Service Processors boot, the Service Processors
run tests.
• When DC power is turned on to boot a partition, the Service Processor first runs
tests.
• When a partition boots, the host processor (BIOS) runs tests.
The partition boot sequence starts when you click Power Up on the summary page of
the remote console interface for a partition. You also can press the power button on the
EXPRESSSCOPE® Monitor interface. The Service Processors are already booted, but
POSTs occur when DC power is turned on and the partitions boot.
The cell state sensor moves through the following states during the boot process, as
identified in the dialog box that identifies the partition state (refer to
Figure 3-3 ):
1. Stopped
2. Initializing
3. Starting
4. Cell check-in
