Note: The front bezel door is not shown so that the drive bays are visible.
System power LED: The states of the system power LED are as follows:
Lit When this LED is lit and not flashing, it indicates that the server is turned
on.
Flashing slowly
When this LED is flashing slowly (once per second), it indicates that the
server is turned off and still connected to an AC power source.
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 will last approximately 20 to 40 seconds.
Note: Approximately 20 seconds after the server is connected to ac power,
the power-control button becomes active.
Off When this LED is off, it indicates that AC power is not present, or the power
supply or the LED itself has failed. A system-power LED is also on the rear
of the server.
Power-control button: Press this button to turn the server on and off manually. A
power-control-button shield comes with the server. You can install this disk-shaped
shield to prevent the server from being turned off accidentally.
Hard disk drive activity LED: When this LED is flashing, it indicates that a hard
disk drive is in use.
System locator LED: Use this LED to visually locate the server among other
servers. You can use IBM Systems Director or IMM to light this LED remotely.
