1 Configuring the OSN|M
You can use the Open Services Networking Module (OSN|M) as an
expansion module installed in an expansion module slot on the rear panel
of a Switch 5500G. The OSN|M runs the Linux operating system (Linux
OS) with which you can load software such as security and voice software
You can log into the OSN|M's Linux system through:
The OSN|M's console port.
The OSN|M's management Ethernet port using SSH.
The OSN|M's internal service interface using SSH
The user interface of the Switch 5500G using serial interface
This chapter introduces how to operate and configure an OSN|M after
you log into the OSN|M's Linux OS using the last method. The OSN|M
configurations on the switch include:
"Switching to the OSN|M's Operating Interface" on page 7
"Restarting the OSN|M's Linux OS" on page 8
For an introduction to other login options, refer to 3Com Switch 5500G
OSN|M Getting Started Guide.
You can log into a switch through its console port or an Ethernet
interface, then connect to the switch's OSN|M or to another switch's
OSN|M in the same fabric. In this case, if the OSN|M's Linux system is
running, the terminal display interface switches from the switch's
command line interface (CLI) to the Linux OS interface. After the
switchover, you can return to the switch's CLI using the shortcut key
To connect to the OSN|M's Linux system, use the
command. This command is available in user view.
