Server POST Tracking

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.

Insufficient Power Notification

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

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.

Hot-plugging a keyboard—Connecting a local keyboard to the keyboard PS2 connector on the server while the server is in a powered-on state.
