Menu Item Description
Serial Communication Allows you to enable the COM port or Console Redirection options.
Serial Port Address Allows you to set the port address for serial devices. By default, the Serial Port Address option
is set to COM1.
Failsafe Baud Rate Displays the failsafe baud rate for console redirection. The BIOS attempts to determine the

Redirection After Allows you to enable or disable to the BIOS console redirection when the operating system is
Boot loaded. By default, the Redirection After Boot option is set to Enabled.
CAUTION: Slot disablement must be used only when the installed peripheral card is
preventing booting into the Operating System or causing delays in system startup. If the
slot is disabled, both the Option ROM and UEFI driver are disabled.
NOTE: Use this option only for troubleshooting purposes. If one or more of the mezzanine
card/PCIe mezzanine card slots are disabled, an error message is displayed during the
system startup.
For proper operation, make sure that the server module has two mezzanine cards/PCIe
mezzanine cards installed and both cards are set to Enabled.
NOTE: Only Serial Device 2 can be used for Serial Over LAN (SOL). To use console
redirection by SOL, configure the same port address for console redirection and the serial
device.
