2. To view the light path diagnostics LEDs, select one of the following procedures:
• You can view the LEDs through the CMM led command, the CMM web interface, the Lenovo XClarity
Administrator (if available), or the Flex System Manager management software (if available).
– For more information about the CMM led command, see the
Module: Command-Line Interface Reference Guide" at http://pic.dhe.ibm.com/infocenter/flexsys/

• If you are in the same location as the compute node, you can complete the following steps:
a. Remove the compute node from the Flex System chassis, (see
chassis" on page 880
b. Carefully lay the compute node on a flat, static-protective surface.
c. Open the compute node cover (see
instructions).
d. Remove the air baffles that are installed over the DIMM connectors.
e. Press the power button. When you press the power button, LEDs on the light path diagnostics
panel and the system board will be lit if there are any hardware-related issues.
Note: The power source for light path diagnostics is designed to last only a short time. If you
press the power button and the light path diagnostics LED lights, light path diagnostics is charged
to light the LEDs.
The following illustration shows the LEDs on the light path diagnostics panel.
The following illustration shows the locations of the light path diagnostics LEDs on the system board.
