Use this information for details about power on the compute
node.
After you connect the compute node to power through the
Lenovo Flex System chassis, the
compute node can be started in any of the following ways.
Important: If an Attention label is on the front panel of the
compute node above the power button, read it; then, remove the label
and discard it before turning on the compute node.
- You can press the power button on the front of the compute node
to start the compute node. The power button works only if local power
control is enabled for the compute node. Local power control is enabled
and disabled through the CMM power command and the CMM web
interface.
Note:
- Wait until the power LED on the compute node flashes slowly before
you press the power button. While the Lenovo XClarity Controller 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. The time required for a compute
node to initialize varies by system configuration; however, the power
LED blink rate slows when the compute node is ready to be turned on.
- While the compute node is starting, the power LED on the front
of the compute node is lit and does not flash.
- If a power failure occurs, the Lenovo Flex System chassis and
the compute node can be configured through the CMM power command
and the CMM web interface to start automatically when power is restored.
- You can turn on the compute node through the CMM power command,
the CMM web interface and the Lenovo XClarity Administrator application
(if installed).
- You can turn on the compute node through the Wake on LAN (WOL)
feature when an optional I/O adapter with WOL capability is installed.
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 interface.
