◦ Reset—Forces the servers in the selected group to warm-boot: CPUs and I/O resources
are reset. Using this option circumvents the graceful shutdown features of the operating
system.
◦ Cold Boot—Immediately removes power from the servers in the selected group.
Processors, memory, and I/O resources lose main power. The servers will restart
after approximately 6 seconds. Using this option circumvents the features for graceful
shutdown of the operating system.

Configuring iLO Federation group power settings
The group power settings feature enables you to set dynamic power caps for your grouped servers.
When using Automatic Group Power Capping, note the following:
•
When a group power cap is set, the grouped systems share power in order to stay below the
power cap. More power is allocated to busy servers and less power is allocated to servers
that are idle.
•
The power caps that you set for a group operate concurrently with the power caps that you
can set on the Power Settings page for an individual server.
•
When a power cap is set, the average power reading of the grouped servers must be at or
below the power cap value.
•
If you want to configure power capping settings for an iLO Federation group, ensure that each
member of the group has granted the Configure iLO Settings privilege to the group. For more
information about privileges, see
“Configuring iLO Federation” (page 7) .
