HP (Hewlett-Packard) HP Integrated Lights-Out ユーザーズマニュアル

Feedback is limited while the server is booting because of the headless nature of 
the ProLiant BL p-Class servers. iLO provides boot-time feedback by flashing 
the Server Health LED green during server POST. The LED is set to solid amber 
if the boot is unsuccessful. The LED is set to solid green at the end of a 
successful boot. 

After a successful boot, control of the Server Health LED is returned to the 
server, which can turn the LED off or set it to some other color to represent the 
health of the server hardware. 

 

iLO turns the Server Health LED solid red if iLO cannot power on the server 
because insufficient power is in the rack infrastructure. 

 

Hot-plug keyboard functionality was implemented for all servers with iLO. The 
hot-plug keyboard feature supports connecting a local keyboard to the server 
while the server is in a powered-on state. It is not necessary to power cycle the 
server to get local keyboard functionality after hot-plugging a keyboard. If a 
keyboard is connected to the server after the operating system has booted, the 
hot-plugged keyboard is fully functional. The keyboard can be hot-plugged 
multiple times after the operating system has booted.
