Power-on LED: When this LED is lit and not flashing, it indicates that the server is
turned on. When this LED is flashing, it indicates that the server is turned off and
still connected to an ac power source. When this LED is off, it indicates that ac
power is not present or the power supply or the LED itself has failed.
Note: If this LED is off, it does not mean that there is no electrical power in the
server. The LED might be burned out. To remove all electrical power from the
server, you must disconnect the power cords from the electrical outlets.
Locator LED: Use this LED to visually locate the server among other servers. You
can use IBM Director to light this LED remotely or press the locator button to light
the LED manually. This LED is also lit during startup.
System-error LED: When this LED is lit, it indicates that a system error has
occurred. An LED on the light path diagnostics panel is also lit to help isolate the
error.
Gigabit Ethernet 2 LED: When this LED flashes, it indicates that there is activity
between the server and the network. When this LED is lit continuously, it indicates
that there is an active connection on the Ethernet port.
Gigabit Ethernet 2 connector: Use this connector to connect the server to a
network.
Gigabit Ethernet 1 LED: When this LED flashes, it indicates that there is activity
between the server and the network. When this LED is lit continuously, it indicates
that there is an active connection on the Ethernet port.
Gigabit Ethernet 1 connector: Use this connector to connect the server to a
network. This connector is shared with the baseboard management controller
