There are up to six IOMs on the managed system.
To connect to an IOM:
connect switch-n
where n is an IOM label A1, A2, B1, B2, C1, and C2.
(See Figure 13-1 for an illustration of the placement of IOMs in the chassis.) When you reference the IOMs in the
connect command, the IOMs are mapped to switches as shown in the following table.
Table 29. : Mapping I/O Modules to Switches
I/O Module Label Switch
A1 switch-a1 or switch- 1
A2 switch-a2 or switch-2
B1 switch-b1 or switch-3
B2 switch-b2 or switch-4
C1 switch-c1 or switch-5
C2 switch-c2 or switch-6
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-nx, 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 see 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 see 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.

Configuring the Managed Server BIOS for Serial Console Redirection
It is necessary to connect to the managed server using the iKVM (see Managing Servers With iKVM ) or establish a
Remote Console session from the iDRAC7 Web interface (see the
iDRAC7 User’s Guide
on dell.com/support/manuals).
Serial communication in the BIOS is OFF by default. To redirect host text console data to Serial over LAN, you must
enable console redirection through COM1. To change the BIOS setting:
1. Boot the managed server.
2. Press <F2> to enter the BIOS setup utility during POST.
