Procedure

Powering Off the System

  1. Gracefully shut down the appliance:

    • Log in using SSH and run:
      • # system poweroff
    • This command performs an orderly shutdown of all processes and powers off the system.
    • Administrative privileges are required
  2. Caution:

    • Do not use the chassis power switch to power off the system.
    • Doing so prevents remote power-on over IPMI and does not perform a clean OS shutdown.

    Example:

    # system poweroff
    The system poweroff command shuts down the system and turns off the power.
    Continue? (yes|no|?) [no]: yes

    • After the controller powers off, turn off expansion shelves (ES20, ES30, DS60):
      • ES20: Use power switches.
      • ES30/DS60/DS120: Disconnect AC power.

Powering On the System

  1. Power on expansion shelves first:

    • ES20: Use power switches.
    • ES30/ES40/DS60: Plug into AC power.
    • Wait approximately 3 minutes after all shelves are powered on.
  2. Power on the controller:

    • Press the power button (refer to the Installation and Setup Guide for your model).
  3. Verify system status:

    • Confirm that the system has fully booted and DDOS is running:
      • Use the system console or SSH login.
      • The system is ready when you can log in successfully.
