Starting a system by using the control panel

You can use the power button on the control panel to start a system that is not managed by a Hardware Management Console (HMC).

1. Open the front rack door, if necessary.
2. Before you press the power button on the control panel, ensure that power is connected to the system unit as follows:
   • All system power cables are connected to a power source.
   • The power LED, as shown in the following figure, is slowly flashing.
   • The top of the display, as shown in the following figure, shows 01 V=F.
3. Press the power button (A), as shown in the following figure, on the control panel.

     • There is approximately a 30-second transition period from the time the power-on button is pressed to when the power LED goes from flashing to solid. During the transition period, the LED might flash faster.
   • B: Enclosure identify light
     • A constant light indicates the identify state, which is used to identify a part.
     • No light indicates that the system is operating normally.
   • C: System information light
     • No light indicates that the system is operating normally.
     • Light on indicates that the system requires attention.
   • D: Enclosure fault roll-up light

   • The system cooling fans are activated after approximately 30 seconds and begin to accelerate to operating speed.
   • Progress indicators, also referred to as checkpoints, appear on the control panel display while the system is being started. The power-on light on the control panel stops flashing and remains on, indicating that the system power is on.
