at startup.
	• The power supplies have malfunctioned.

The red light on the back of the 201i board is on.

The DSP card socket light is on, but no DSP card is plugged in.

The server does not fit or seat properly into the shelf.

The green HEX display indicates that the system works properly and you hear the hard drive spin, but no information is displayed on screen.

•The 8051 system controller failed.

The 8051 system controller and the HEX display work together and perform a quick system hardware test before the operating system starts up.

Refer to the 201i Server Maintenance and Diagnostics document (NN44200-705) for information on interpreting the HEX display.

The onboard DSP field programmable gate array (FPGA) is not loading properly. Sometimes the system boots to the operating system, but CallPilot does not function. Declare the system an OBF and return it to the channel partner.

The DSPs failed to load. Sometimes the system boots to the operating system, but CallPilot does not function. Declare the system an OBF and return it to the distributor.

ATTENTION

Do not force the 201i server into the shelf.

Ensure that you set the proper physical spacing on the back of the server. The Option 11 and Meridian 1* cabinets have two different card-spacing options. Use a Phillips screwdriver to adjust the bracket on the back of the 201i server (the backplane card edge connector). Refer to the 201i Server Hardware Installation guide (NN44200-301).

Verify that the monitor is properly connected to the power supply and to the CallPilot server. Ensure that the monitor is not defective.

If the system still does not display information on screen, then declare the system an OBF and return it to the distributor.
