Default Serial/Modem Configuration Settings Set By the SMU
The SMU sets some serial/modem configuration settings automatically. This information is
listed below, but is not displayed on the screen. The list of these settings is given below.
Before this information is set by the SMU, you must click through the remaining Serial/Modem
Channel Configuration sub-task screens to click the Save button on the last screen.
• Authentication type enables are enabled. These bits define what types of authentication are
enabled to authenticate messages sent to the BMC by users of different privilege levels.
The SMU enables authentication of type straight password, MD2, MD5, and none.
• Basic mode is enabled, allowing basic serial communications to take place over the
serial/modem channel.
• Session inactivity timeout is set to one minute.
• Session termination bits are enabled to enable ending of a serial/modem session if an
inactivity timeout occurs or if DCD is lost.
• Flow control and baud rate are set for IPMI messaging (flow control is set to hardware flow
control; the baud rate is set to 19.2 kbps).
• The multiplexor that determines who controls the serial connector has various default
settings enabled and disabled.
Connection Mode
The connection mode determines the protocols used when performing IPMI messaging to the
BMC. After selecting a connection mode, clicking on the Next button displays the screen for
the selected mode.
• Direct Connect Mode: When Direct Connect Mode is selected, the client console and
target server are connected by a null modem cable attached between the serial ports of each
system.
• Modem Mode: When Modem Mode is selected, the client system establishes a connection
to the target server using a modem. Each system must have a modem attached, and the user
on the client system must have the dial string for the modem connected to the target server.
Access Mode
This option is used to configure the access mode for the Serial/Modem channel. The choices
are:
• Pre-boot only: The Serial/Modem channel is available only out-of-band while the machine
is powered-off and during POST until the boot process is initiated. This option is primarily
used with serial port sharing where it may be desirable to ensure that the BMC does not
control the serial port while the operating system is running. The Pre-boot only setting does
not affect Serial/Modem alerting. If alerting is enabled and software does not handle the
event, the BMC takes control of the port for the time that it takes to deliver the alert.
• Always Available: The channel is dedicated to communication with the BMC and is
available during all system states (powered-down, powered-up, pre-boot, sleep, run-time,
etc.).
• Shared: Shared is the same as Always Available, but the BIOS leaves the serial port
available for software use.
• Disabled: The channel is not allowed to communicate with the BMC except for alerting.
