Front Panel IO (FPIO) Server board

Introduction

This chapter describes the basic functions and interface requirements of the Front Panel IO (FPIO) server
board that is designed for the server.

Features

The server has the following FPIO features:
•
Four switches to control power-on, reset, NMI, and the system ID LED
•
One system ID LED that can be controlled remotely or by the system ID switch
•
Two system activity LEDs that indicate power-on and NIC activity
•
Two hard drive activity/fault LEDS that indicate activity/fault status for drives 1 and 2
•
Four system fault LEDs that indicate critical, major, minor, and power system fault status
•
Four system fault relays for external critical, major, minor, and power fault indicators
•
One SCSI bus with hot-swap circuitry for controlling hot-swap SCSI disk drives 1 and 2 (not supported
on the initial release of the server)
•
IDE bus from IDE connector to blind mate connector
•
Floppy bus from floppy connector to blind mate connector
•
One blind mate connector for interfacing to CD ROM or CD+RW/DVD carrier assembly
•
Connectors for interfacing to the power supply, server baseboard, drive carrier assemblies, and hot-plug
disk drives 1 and 2

FPIO SCSI Subsystem Status LEDs

The status LEDs give the user a visual indication of the internal disk drives' condition. There is a single
LED for each drive. The LEDs are bi-colored and use a combination of color and blinking frequency to
indicate multiple conditions. The LEDs are mounted on the FPIO board, and the light is directed to the front
panel through the use of a light pipe assembly. Refer to Table 3-1 for LED activity definitions. Refer to the
Firmware EPS for definitions of the different blink rates.
