Connecting to Servers or I/O Modules Using Connect
Command
CMC can establish a connection to redirect the serial console of server or I/O modules.
For servers, serial console redirection can be accomplished using:
• racadm connect command. For more information, see Chassis Management Controller for Dell
PowerEdge M1000e RACADM Command Line Reference Guide at dell.com/support/manuals.
• iDRAC Web interface serial console redirection feature.
• iDRAC Serial Over LAN (SOL) functionality.
In a serial, Telnet, SSH console, the CMC supports the connect command to establish a serial connection
to server or IOM modules. The server serial console contains both the BIOS boot and setup screens, and
the operating system serial console. For I/O modules, the switch serial console is available.
CAUTION: When executed from the CMC serial console, the connect -b option stays connected
until the CMC resets. This connection is a potential security risk.
NOTE: The connect command provides the –b (binary) option. The –b option passes raw binary
data, and cfgSerialConsoleQuitKey is not used. Additionally, when connecting to a server using
the CMC serial console, transitions in the DTR signal (for example, if the serial cable is removed to
connect a debugger) do not cause a logout.
NOTE: If an IOM does not support console redirection, the connect command displays an empty
console. In that case, to return to the CMC console, type the Escape sequence. The default console
escape sequence is <CTRL><\>.
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 32. : 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
