Required Equipment

Shutting Down and Powering Off the Appliance
The appliance can run in two power modes:
• Main power mode—Power is supplied to all appliance components and the operating system.
• Standby power mode—Power is supplied only to the service processor and the cooling fans and it
is safe to power off the appliance from this mode.
You can gracefully shut down the appliance by using the shutdown command or the Power button on the
appliance front panel, as described in the following steps:
Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section on page 3-2).
• Green—The appliance is in main power mode and must be shut down before it can be safely powered
off. Go to Step 2.
• Amber—The appliance is already in standby mode and can be safely powered off. Go to Step 3.
Step 2 Use one the following methods to shut down the appliance. If possible, invoke a graceful shutdown.
Otherwise invoke a hard shutdown:
Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown
of the operating system.
• Graceful shutdown using the CLI—Enter the shutdown command. The operating system performs a
graceful shutdown and the appliance goes to standby mode, which is indicated by an amber Power
Status LED.
• Graceful shutdown using the front panel—Press and release the Power button. The operating system
performs a graceful shutdown and the appliance goes to standby mode, which is indicated by an
amber Power Status LED.
• Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off
and immediately enter standby mode.
