A frequent search term on my blog relates to how to turn off an HP C3000 Blade Enclosure.
Here is the basic procedure:
- Shutdown any server blades in the enclosure e.g. via the Operating System.
- Logon to the C3000’s Onboard Administrator (OA) from a remote computer using the OA web interface.
- In the OA menu choose either Shutdown or Reboot.
Information on configuring the OA can be found here Configuring HP C3000 Onboard Administrator
Note that you can also use iLO to power on/off individual blades in the enclosure remotely.
