Multi-Color LED The CME34M has a Multi-Color LED which can be enabled or disabled in the BIOS setup screen. The color of the LED indicates the status of the board, as shown in Table 53. Table 53 LED Colors Color Description Green Blue Normal Operation SATA Activity Red cpuModule is in reset 1 Yellow (Red + Green) cpuModule is in Standby White (R+G+B) cpuModule is approaching thermal limit 2 Cyan (Blue + Green) Magenta (Blue + Red) Blink Ethernet Link at 100 Mbps or Bus Stacking Error Ethernet Link at 1000 Mbps Ethernet Activity 1. If power is applied to the cpuModule while jumper JP5 is installed, the LED will be red. This does not indicate that the board is in reset 2. The LED will remain White until the system is shut down. The LED can also be controlled manually by writing to I/O Port 984h, as shown in Table 54 and Table 55 Table 54 Multi-Color LED I/O Address 984h D7 D6 D5 D4 D3 D2 D1 D0 Reserved Reserved Reserved Reserved Reserved Multi-Color LED The following table lists the color displayed and the value written. Table 55 Manual LED Colors I/O Port 984h Value Color 0x00 Automatic (see Table 53) 0x08 Off (will reduce system power consumption.) 0x09 Blue 0x0A Green 0x0B Cyan (Green + Blue) 0x0C Red 0x0D Magenta (Red + Blue) 0x0E Yellow (Red + Green) 0x0F White (Red + Green + Blue) 70 CME34M cpuModule BDM-610000076 Rev A
Reset Status Register The cpuModule has several different signals on board which can cause a system reset. If a reset occurs, the reset status register can be used to see which reset or resets have been asserted on the cpuModule. The user has the ability to see which resets have been asserted. Resets can also be cleared. • Examine Resets: Reading from I/O port 0x987 will indicate if a reset has been asserted. If a 1 is read, the corresponding reset has been asserted. If a 0 is read from the bit, the reset has not been asserted • Clear Reset: Each reset can be cleared by writing a 1 to the selected bit of I/O port 0x987.
