MegaRAC M300V card not present. The motherboard’s serial connector behaves as normal. MegaRAC M300V card is present and the MegaRAC M300V card is on SoL mode. The MegaRAC M300V card’s UART0 signals are routed to the motherboards serial port connector. -
Page 69: Megarac M300V Card Present And On Sol Mode (Default)
In this configuration the X4 De-MUX direction is from Y to A and the X5 MUX direction is from B to Y. In this configuration the MegaRAC M300V card can re-direct the SoL input serial data to a remote location through the MegaRAC M300V card’s dedicated LAN. Additionally the SoL input serial data can be viewed via the MegaRAC M300V card UART0 through the motherboard’s serial connector simultaneously. -
Page 70: Megarac M300V Card Present And In Non-Sol Mode
The motherboard UART TXD and RXD signals are routed to the motherboard’s serial connector through MegaRAC M300V card. The MegaRAC M300V card UART1 monitors the RXD signal for an escape (ESC) sequences so that it can switch between SoL Mode and Non-SoL Mode. The motherboard UART control signals are routed to motherboard’s serial connector. -
Page 71: Chapter 8 Motherboard Hardware Support
Interface Signal Specification. Fan Tachometer Read Back The MegaRAC M300V card reads the fan tachometers through a 16:4 multiplexer located on the motherboard. Only four fan tach signals are provided across the OPMA connector as inputs to the MegaRAC M300V card. The 16:4 multiplexer is controlled by four MUX select signals provided across the OPMA connector and the MegaRAC M300V card controls these signals to select one bank of up to four fans to be monitored at a time. -

Page 73: Fan Speed Control
The motherboard must provide the necessary circuit that converts PWM pulses from the MegaRAC M300V card output to an analog DC level that is then amplified to actually control the fans. It is part of the fan speed control circuit. The illustration below shows the block diagram of the fan speed control circuit. -
Page 74: Clear Cmos Circuit
The motherboard must provide hardware circuitry for clearing the BIOS CMOS contents when the MegaRAC M300V card BMC activates the output to clear the CMOS. This provides a remote, software controlled way of clearing the system CMOS without having to open the system chassis. -
Page 75: System Speaker Control Circuit
System Speaker Control Circuit The motherboard must provide the hardware circuitry for the MegaRAC M300V card to share control of the system speaker (transducer) with the Southbridge or I/O hub. This circuitry allows the MegaRAC M300V card to drive the system speaker with the MCARD_SYS_SPKR_DATA signal to generate audible alerts. -
Page 76: Local Access Lock Out
Using this recommended but optional feature, the MegaRAC M300V card may be commanded remotely to lock out some or all local console access to its host. Lock out, if implemented, should disable local access to front panel reset, power and NMI switches as a minimum. -

Page 81: Bios/Firmware Considerations
BIOS should not halt the boot process or require keystroke input on any sort of BMC related error; the absence of the MegaRAC M300V card should never stop a server from booting up. Any reference in the following paragraphs to BIOS printing messages to the boot screen should be taken to mean that BIOS must write the indicated message to the text-based BIOS POST screen that is displayed during POST. -
Page 82: Management Subsystem Host Interface Type Encoding
If the interface ID bits remain 111b for the full 25 seconds, BIOS should assume that a problem exists with the MegaRAC M300V card and print this fact to the POST screen. BIOS must wait an additional 50 ms beyond the initial detection of any pattern other than 111b before taking a final INTERFACE_ID reading. -
Page 83: Megarac M300V Card Presence, Health And Bmc Firmware Revision Reporting
The system BIOS must print a POST screen message that indicates whether or not the MegaRAC M300V card was detected as being present. If the MegaRAC M300V card is present, the BIOS must determine if an IPMI command interface is present on the MegaRAC M300V card that the BIOS know how to communicate with. -
Page 84: System Identification
The system BIOS must contain a system identification OEM ID and management sensor implementation ID. The BIOS communicates this information to the BMC as part of the POST BIOS-BMC synchronization process. 78 MegaRAC® M300V Card Implementer’s Reference and User’s Guide... -
