Powering On the CH225 V3


You can use any of the following methods to power on the compute node:

  • If the chassis is powered off, power it on. The compute node is powered on along with it.
  • If the chassis is powered on and the compute node is not installed, the compute node is powered on automatically after it is installed.
  • If the chassis is powered on and the installed compute node is abnormal, hold down the power button on the front panel for 6 seconds to power off the compute node and press the power button again to power it on.
