Turning On The Compute Node - IBM Flex System p260 Installation And Service Manual

4. Enclosure fault LED: When this amber LED is lit, it indicates that a system error has occurred in the
compute node. The compute-node error LED will turn off after one of the following events:
v Correcting the error
v Reseating the compute node in the IBM Flex System Enterprise Chassis
v Cycling the IBM Flex System Enterprise Chassis power

After reading the required safety information, look at the control panel to determine whether the LEDs
indicate a suboptimal condition or an error.

Turning on the compute node

After you connect the compute node to power through the IBM Flex System Enterprise Chassis, you can
start the compute node after the discovery and initialization process is complete.
About this task
To start the compute node, use one of the following methods:
Procedure
v Start the compute node by pressing the power-control button on the front of the compute node.
After you push the power-control button, the power-on LED continues to flash slowly for about 15
seconds, and then is lit solidly when the power-on process is complete.
Wait until the power-on LED on the compute node flashes slowly before you press the compute node
power-control button. If the power-on LED is flashing rapidly, the service processor is initializing the
compute node. The power-control button does not respond during initialization.
Note: The enhanced service processor can take as long as 3 minutes to initialize after you install the
compute node, at which point the LED begins to flash slowly.
v Start the compute node automatically when power is restored after a power failure.
If a power failure occurs, the IBM Flex System Enterprise Chassis and then the compute node can start
automatically when power is restored. You must configure the compute node to restart through the
management module.
v Start the compute node remotely using the management module.
After you initiate the power-on process, the power-on LED flashes slowly for about 15 seconds, and
then is lit solidly when the power-on process is complete.
