appropriate menu. The menu configured above, for one of the defined users (sandy, dave bob, kathy,
default), would look like the one shown below:

3.5 Managing the Attached Devices
You can manage the SCS’s connected serial devices over a network connection or through a modem
connection. Both of these methods ensure that the SCS and its attached serial devices are always accessible
and manageable, even in critical situations.
3.5.1 In-Band Management
The SCS provides TCP/IP socket connections to its serial ports. A TCP session to port 30xx, where xx is the
serial port number, will form a raw TCP/IP connection to that serial port. A connection to port 20xx provides
Telnet IAC interpretation.
Figure 3-12: Telnet IAC Connection to the Second Serial Port
To connect to a specific SCS port using SSH, use socket number 22xx, where xx is the port number. The
syntax for an SSH connection depends on your client software. SSH is discussed in SSH Sessions on page
6-10.

3.5.2 Out of Band Management
To ensure that you can manage attached equipment even if there are network problems, the SCS provides
an out-of-band management feature. If you have a modem connected to one of the SCS serial ports, you can
access and manage the SCS via a dial-in modem connection.
Instructions on modem configuration are available in Chapter 9, Modems.
To dial-in to the SCS,
1 Open a terminal emulator such as Hyperterminal
2 Dial the phone number for the modem attached to the SCS.
