NOTE: There can only be one IOM connection per chassis at a time.

NOTE: You cannot connect to pass-throughs from the serial console.

To connect to a managed server serial console, use the command connect server-<n><x>, where n

is 1-8 and x is a,b, c, or d. You can also use the racadm connect server-n command. When you

connect to a server using the

-b option, binary communication is assumed and the escape character is

disabled. If the iDRAC is not available, you see a No route to host error message.

The connect server-n command enables the user to access the server's serial port. After this

connection is established, the user can view the server's console redirection through CMC's serial port

that includes both the BIOS serial console and the operating system serial console.

NOTE: To view the BIOS boot screens, serial redirection has to be enabled in the servers’ BIOS

Setup. Also, you must set the terminal emulator window to 80x25. Otherwise, the screen is garbled.

NOTE: Not all keys work in the BIOS setup screens, so provide appropriate escape sequences for

CTRL+ALT+DEL, and other escape sequences. The initial redirection screen displays the necessary

escape sequences.
