11 PowerEdge MX7000 Chassis Power Sequence
4.2 Chassis Power OFF: Graceful shutdown.
A graceful chassis power off sequence will cause chassis internal components to be powered OFF gracefully.
In this mode if sled host cannot be shutdown gracefully then chassis will not power OFF, it will go back to
chassis power ON state. Now user has option to either trigger graceful shutdown again or if user wants to
shutdown chassis immediately then ungraceful shutdown can be triggered.
User can initiate graceful shutdown from power button or from OME GUI.
• Initiating graceful shutdown from OME GUI is straightforward, section 4.1 shows the screenshot.
• Initiate graceful shutdown using the RCP power button by pressing and holding the button for 1
second.
4.3 Chassis Power OFF: Un-Graceful shutdown.
An un-graceful chassis power off sequence will cause chassis internal components to be powered OFF
forcefully. In this mode sled hosts will be forcefully shutdown with a risk of data loss.
Initiate un-graceful shutdown from Power button or from OME GUI.
• Press and hold the chassis power button for >6 seconds to initiate un-graceful shutdown.
• To use OME GUI, select the “Power Off (non-graceful)” option from the GUI, see 4.1 for screenshot.
