Test
1 When pressing one of the LCD status
panel buttons, nothing is displayed.
2 When the system is powered on, nothing is
displayed.
Presence of a processor in the BOOT PROC [1]
processor slot. This is test is for a single
processor system only.
Presence of either CPU or Terminator in the
processor slot.
Number of installed DIMMs
Control of some voltages: VRMs, 12V
Test of the correct power signals to the CPU.
The power supply may be OK, whereas the VRM
is not.
Presence of VRMs and their associated
processor.
Presence of a VRM in VRM socket 2. This test is
for both single and dual processor systems.
Check the system board clock generators (PLL).
Compatibility of DIMMs. The BIOS checks that
the inserted DIMMs are both compatible with
one another, and compatible with the Front Side
Bus frequency.
Error Code
LCD status panel • Check that the two cables to the LCD status panel are properly
is blank connected (refer to the system board layout for position).
• Check that the PC's power cable is plugged in.
NO CPU 1 • Check that the processor is correctly installed in the BOOT
PROC [1] slot.
CPU SOCKET • Check CPUs and Terminator and VRM of installed processor.
NO RAM • Check that the memory module is correctly installed in the
memory socket.
POWER SUPPLY • Check the power supply connectors, VRM, CPU. In a single
processor system, check that the VRM is not plugged into the
terminator socket.
The error message could also show: Power CPU1 and Power
CPU2.
POWER • Check that the VRM, processor and terminator are correctly
installed.
• Check that the VRM is not plugged on a socket with a
terminator (this could be the likely cause).
• Check or replace the VRM.
• Check the power supply unit connectors.
POWER CPU • Check that the VRMs are correctly installed in their VRM
sockets.
POWER CPU 1 - Check VRMs sockets 1 and 2.
POWER CPU 2 - Check VRM socket 3.
POWER CACHE • Check that the VRM is correctly installed in VRM socket 2.
BOARD PLL • Check the power supply connector.
• Replace the system board (PLL clock generator).
RAM TYPE • Check the installed memory modules. This error occurs when
mixing incompatible memory modules, for example, when
installing a 66 MHz DIMM on a 350 MHz or higher system, or
when mixing Unbuffered and Registered memory modules.
