Turning Off The Compute Node - Lenovo Flex System x440 Compute Node Installation And Service Manual

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.

– From the CMM web interface, select Compute Nodes from the Chassis Management menu. All fields
and options are described in the CMM web interface online help. For more information, see the

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" on page 14
• If a power failure occurs, the 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, the
Lenovo XClarity Administrator (if available), or the Flex System Manager management software (if
available).

• You can turn on the computer node through the Wake on LAN feature. The computer 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.
