Figure 3-6 Ports, controls and LEDs located on the front operator panel
The front operator panel contains the following controls:
Power button/LED: Press the power 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: Input power is not present, or the power supply or the LED itself has failed.
– Flashing rapidly (3 times per second): The server is turned off and is not ready to be
turned on. The power-on button is disabled. This lasts approximately 10 seconds after
input power has been applied or restored.
– Flashing slowly (once per second): The server is turned off and is ready to be turned
on. You can press the power-on button to turn on the server.
– Lit: The server is turned on.
Locate button/LED: Press the locate button to visually locate the server among other
servers. When you press the locate button, the LED will be lit and it will continue to be lit
until you press it again to turn it off.
Check log LED: When this LED is lit (yellow), it indicates that a noncritical event has
occurred, such as the wrong I/O book inserted in a bay, or power requirements that
exceed the capacity of the installed power supplies.
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. This LED is controlled by
the IMM2.
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.
The Reset button is in the upper-right corner of the front operator panel.
PCIe slots 11 and 12 error LEDs: When these LEDs are lit, they indicate that an error
has occurred in PCIe slots 11 and 12 on the storage book board.
