Power-on button/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: 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.
v
Ethernet port 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.
v
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 other servers. It is also used as the physical presence for
the Trusted Platform Module (TPM).
v
Check log LED: When this amber LED is lit, it indicates that there are errors
that require further diagnosis. Check the IMM event log for additional
information. See “Event logs” on page 166 for more information about event
logs.
v
System-error LED: When this amber 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.
