The following illustrations show the location of the operator information panel and the LEDs on the operator information panel respectively.
Figure 1. Operator information panel
- Power-control button and power-on LED: Press this button to turn the server on and off manually or to wake the server from a reduced-power state. The states of the power-on LED are as follows:
- Off: AC power is not present, or the power supply or the LED itself has failed.
- Flashing rapidly (4 times per second): The server is turned off and is not ready to be turned on. The power-control button is disabled. This lasts approximately 1 to 3 minutes.
- Flashing slowly (once per second): The server is turned off and is ready to be turned on. You can press the power-control button to turn on the server.
- Lit: The server is turned on.
- Fading on and off: The server is in a reduced-power state. To wake the server, press the power-control button or use the IMM web interface. See Logging on to the Web interface for information on logging on to the IMM web interface.
- Ethernet activity LEDs: When any of these LEDs is flashing or flickering, it indicates that the server is transmitting to or receiving signals from the Ethernet LAN that is connected to the Ethernet port that corresponds to that LED.
- Locator button/LED: Use this blue LED to visually locate the server among other servers. This LED is also used as a presence detection button. You can use IBM Systems Director to light this LED remotely. This LED is controlled by the IMM. When you press the locator button, the LED will be lit and it will continue to be lit until you press it again to turn it off. Press the locator button to visually locate the server among the others servers. It is also used as the physical presence for the Trusted Platform Module (TPM).
- Log LED: When this yellow LED is lit, it indicates that a noncritical event has occurred. Check the system-event log for additional information. See Error messages for more information about event logs.
- System-error LED: When this yellow LED is lit, it indicates that a system error has occurred. A system-error LED is also on the rear of the server. An LED on the light path diagnostics panel on the operator information panel is also lit to help isolate the error. This LED is controlled by the IMM.
- Reset button: Press this button to reset the server and run the power-on self-test (POST). You might have to use a pen or the end of a straightened paper clip to press the button.
All the operator information is on the operator information panel already. You do not need to pull the panel out for obtaining more information.
