Chapter 2. Power, Controls, Indicators, And Connectors; Compute Node Control Panel Button And Leds - IBM Flex System p260 Installation And Service Manual

Chapter 2. Power, controls, indicators, and connectors

You can use the control panel to turn the compute nodes on or off and to view some controls and
indicators. Other indicators are on the system board. The system board also has connectors for various
components.

Compute node control panel button and LEDs

Compute node control panel button and LEDs provide operational controls and status indicators.
Figure 1. Compute node control panel button and LEDs
1. Power-control button and light path LED: Press this button to turn on or turn off the compute node
or to view light path diagnostic LEDs.
The power-control button has an effect only if local power control is enabled for the compute node.
Local power control is enabled and disabled through the web interface of the management module.
Press the power-control button for 5 seconds to begin powering down the compute node.
The green light path LED indicates the power status of the compute node in the following manner:
v Flashing rapidly: The service processor is initializing the compute node.
v Flashing slowly: The compute node has completed initialization and is waiting for a power-on
command.
v Lit continuously: The compute node has power and is turned on.
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.
2. Location LED: When this blue LED is lit, it has been turned on by the system administrator to aid in
visually locating the compute node. The location LED can be turned off through the management
console.
3. Check log LED: When this amber LED is lit, it indicates that an error for the compute node has been
detected that must be addressed by the user. See the error log repository to further investigate this
serviceable event. The LED can be turned off through the management console.
