12.2 Functional Architecture

This section provides a more detailed architectural description of the front panel I/O board's
functional blocks.
12.2.1

VGA

The front panel I/O board passes the VGA video signals from the main board 100-pin connector
to the external video connector.
12.2.2

USB

The front panel I/O board contains a high-speed USB 2.0-compliant controller hub that provides
three external USB ports. The controller is accessible through the I
12.2.3

FRU

The front panel I/O board contains FRU information EEPROM, accessible through the I
at address HEX A6.
12.2.4

Thermal Sensor

A thermal sensor is located on the front panel I/O board to sense ambient air temperature. It is
2
located on the I C bus at address HEX 98.
12.2.5

50-pin Control Panel Connector

A separate front panel control module interfaces to the front panel board through a 50-pin
connector. The following input functions are routed to the main board: reset, power and chassis
ID. The following LEDs are activated through the connector:
Hard drive status
NIC1 and NIC2 activity
System status
Power and system ID
12.2.6

Speaker

The front panel board contains the drive circuitry and the system speaker.
12.2.7

NMI Button

The front panel I/O board has the system NMI button and routes the signal to the 100-pin
connector.
12.2.8

Main Board and SAS Backplane Connectors

The front panel I/O board contains the 100-pin connector that interfaces with the main board.
Required signals are routed to a 34-pin connector that interfaces to the SAS backplane.
