Configuring CMC to Use Command Line Consoles 57

While 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,

as well as 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

will display 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, type:

connect switch-

where n is an IOM label a1, a2, b1, b2, c1, and c2.

IOMs are labeled A1, A2, B1, B2, C1, and C2. (See Figure 10-1 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 Table 3-4.

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

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