The following controls, LEDs, and connectors are on the operator information panel:
v Power-control button: Press this button to turn the server on and off manually.
A power-control-button shield comes installed on the server to prevent the server
from being turned off accidentally.
v 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 a power source. When this LED is off, it indicates that
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 cord from the electrical outlet.
Attention: In a dc power environment, only trained service personnel other than
Lenovo service technicians are authorized to connect or disconnect power to the
dc power supply. See the documentation that comes with each dc power supply.
v Hard disk drive activity LED: When this LED is flashing, it indicates that a hard
disk drive is in use.
v System-locator LED: Use this LED to visually locate the server among other
servers.
