995 Front Panel Assembly R0-Gateway Part number 8007029

The front panel board has five momentary switches and six LEDs visible through the chassis front bezel. The five switches control power on/off, sleep mode, system reset, chassis ID, and non-maskable interrupt (NMI). The NMI switch is accessible via a small hole in the front of the chassis once the front bezel door is open and requires a small instrument to push it.

The six front panel LEDs are:

• Power-on LED: Solid green indicates system power in a steady-on state. Blinking green indicates Advanced Configuration and Power Interface (ACPI) sleep mode.
• LAN 1 activity LED: This is green during network activity.
• LAN 2 activity LED: This is green during network activity.
• HDD activity LED: Green indicates system hard drive activity and amber indicates hard drive fault.
• Chassis ID LED: Blue LED provides system identification to aid in servicing.
• System status: Green indicates normal system status and amber indicates fault for power supply, hard drive, or cooling subsystem.

The front panel also contains five connectors:

• A 34-pin connector provides control and status information to/from the baseboard.
• Two internal 10-pin connectors provide data and power for the USB and serial port B RJ45 ports.
• Two external connectors provide data and power for the external USB and RJ-45 Serial B ports.

The front panel board mounts to sheet metal at the front of the server and this is secured to the chassis with one 6-32 screw.

In addition, the front panel board has a 24C02LM8 serial EEPROM for Field Replaceable Unit information access. The 24C02LM8 has an I2C slave address of 0xA0/A1h.The front panel board has a DS1621S digital thermostat for measuring ambient air temperature inside the server. The DS1621S has an I2C slave address of 0x9A/9Bh.
