SE7500CW2 Server Board Technical Product Specification
3.2.4.6
Power Management
One of the embedded functions of the ICH3-S is a power management controller. The
SE7500CW2 server board uses this to implement ACPI-compliant power management features.
The SE7500CW2 supports sleep states S0, S4, and S5.

Super I/O
The Windbond** 83627HF Super I/O device contains all of the necessary circuitry to control two
serial ports, one parallel port, floppy disk, PS/2-compatible keyboard and mouse, and hardware
monitor controller. The SE7500CW2 server board supports the following features:
•
GPIOs
•
Two serial ports
•
Floppy
•
Keyboard and mouse
•
Local hardware monitoring
•
"Wake-on" control
3.3.1
Serial Ports
The SE7500CW2 server board provides two serial ports, an external serial port, and an internal
serial header. The following sections provide details on the use of the serial ports.
3.3.1.1
Serial 1
Serial 1 is a standard DB9 interface located at the rear I/O panel of the server board, to the left of
the video connector below the parallel port connector. Serial port 1 is designated by silkscreen
"Serial 1" and reference designator J44.
3.3.1.2
Serial 2
Serial 2 is an optional port, accessed through a 9-pin internal header (J28). A standard DH-10 to
DB9 cable can be used to direct serial 2 to an external connector on any given chassis. The
serial 2 interface follow the standard RS232 pin out. The baseboard has a "Serial 2" silkscreen
label next to the connector. The serial number 2 connector is located just below PCI slot 5.
3.3.1.3
Floppy Disk Controller
The floppy disk controller (FDC) in the SIO is functionally compatible with floppy disk controllers
in the DP8473 and N844077. All FDC functions are integrated into the SIO including analog data
separator and 16-byte FIFO. The SE7500CW2 provides a standard 36-pin interfaces for the
floppy disk controller.
