Turning on the compute node

After you connect the compute node to power through the Lenovo NeXtScale n1200 Enclosure, the compute node can be started in any of the following ways:

• You can press the power button on the front of the compute node (see Compute node controls, connectors, and LEDs) to start the compute node. The power button works only if local power control is enabled for the compute node.
  Note

  1. Wait until the power LED on the compute node flashes slowly before you press the power button. While the IMM2 in the compute node is initializing and synchronizing with the Chassis Management Module, the power LED flashes rapidly, and the power button on the compute node does not respond. This process can take approximately 90 seconds after the compute node has been installed.
  2. While the compute node is starting, the power LED on the front of the compute node is lit and does not flash. See Compute node controls, connectors, and LEDs for the power LED states.
• You can turn on the compute node through the Wake on LAN feature. The compute node must be connected to power (the power LED is flashing slowly) and must be communicating with the Chassis Management Module. The operating system must support the Wake on LAN feature, and the Wake on LAN feature must be enabled through the Chassis Management Module web interface.
