3.7.2 Floppy Disk Controller
The server board does not support a floppy disk controller (FDC) interface. However, the
system BIOS does recognize USB floppy devices.
3.7.3 Keyboard and Mouse Support
Dual stacked PS/2 ports, located on the back edge of the server board, are provided for
keyboard and mouse support. Either port can support a mouse or keyboard. Neither port
supports hot plugging. The system can boot without an attached keyboard or mouse. If present,
the BIOS detects the keyboard during POST and displays the message “Keyboard Detected” on
the POST Screen.
3.7.4 Wake-up Control
The super I/O contains functionality that allows various events to power-on and power-off the
system.
3.7.5 System Health Support
The super I/O provides an interface via GPIOs for BIOS and Server Management firmware to
activate the Diagnostic LEDs, the FRU fault indicator LEDs for processors, DIMMs, fans and the
system status LED. Refer to Figure 3 for the location of the LEDs on the server board.
The super I/O also provides PWM fan control to the system fans, monitors tach and presence
signals for the system fans, and monitors server board and control panel temperature.
