IMM heartbeat

IMM heartbeat boot process.

The following steps describe the

 

 

different stages of the IMM heartbeat

 

 

sequencing process.

 

 

1. When this LED is blinking fast

 

 

(approximately 4Hz), this

 

 

indicates, that the IMM code is in

 

 

the loading process.

 

 

2. When this LED goes off

 

 

momentarily, this indicates that

 

 

the IMM code has loaded

 

 

completely.

 

 

3. When this LED goes off

 

 

momentarily and then starts

 

 

blinking slowing (approximately

 

 

1Hz), this indicates that IMM is

 

 

fully operational. You can now

 

 

press the power-control button to

 

 

power-on the server.

 

 

4. If this LED does not blink within

 

 

30 seconds of connecting a power

 

 

source to the server, complete the

 

 

following steps:

 

 

a.

(Trained service technician

 

 

 

only) use the IMM recovery

 

 

 

jumper to recover the firmware

 

 

 

(see “System-board switches

 

 

 

and jumpers” on page 30).

 

 

b.

(Trained service technician

 

 

 

only) replace the system

 

 

 

board.

 

 

 

 

Server power features

When the server is connected to an ac power source but is not turned on, the operating system does not run, and all core logic except for the service processor (the Integrated Management Module) is shut down; however, the server can respond to requests to the service processor, such as a remote request to turn on the server. The power-on LED flashes to indicate that the server is connected to ac power but is not turned on.

Turning on the server

Approximately 5 seconds after the server is connected to ac power, one or more fans might start running to provide cooling while the server is connected to power and the power-on button LED will blink quickly. Approximately 1 to 3 minutes after the server is connected to ac power, the power-control button becomes active (the power-on LED will blink slowly), and one or more fans might start running to provide cooling while the server is connected to power. You can turn on the server by pressing the power-control button.

The server can also be turned on in any of the following ways:

vIf a power failure occurs while the server is turned on, the server will restart automatically when power is restored.
