10 PowerEdge MX7000 Chassis Power Sequence
4 Chassis Power OFF sequence.
Diagram below shows chassis Power OFF sequence. The sequence that we power off components in the
chassis is exactly reverse order of the power on sequence in the previous section. One important detail is that
normal power off requests are “graceful”. A graceful shutdown request means that IDRAC on individual sleds
will perform and ACPI request to the OS to initiate a graceful shutdown. If any OS on any blade fails to
complete a graceful shutdown, then the chassis power off will abort and the chassis will remain on.
4.1 User initiated Chassis Power OFF request
To power OFF the chassis press the power button on Right control Panel or initiate Power OFF command
from the OpenManage Enterprise Modular (OME) GUI, or OpenManage Mobile (OMM).
There are two different modes to Power OFF chassis.
• Graceful shutdown.
• Ungraceful shutdown.
