Overview
The Open Network Install Environment (ONIE) is a small Linux-based operating
system that provides an open install environment for network switches without
operating systems.
ONIE enables a network switch ecosystem where end-users can choose among
different Network Operating Systems (NOS). Practically, ONIE boots on a switch,
discovers NOS installer images available on the local network or USB drive, copies
the chosen image to the switch, and provides an environment where the installer
can load the NOS onto the switch.
ONIE is classified as free software, meaning it can be redistributed and/or modified
under the terms of version 2 of the GNU General Public License as published by the
Free Software Foundation. To read the license, visit the following link:

Mini-USB Serial Console Port
The mini-USB port on the front management panel is available for switch console
management. The port operates using RS-232 serial communications. A compatible
console cable kit is included with the switch.
To connect a computer or terminal to the switch using the included kit, first connect
the console cable to the mini-USB port on the front panel. Connect one end of the
Category 5 patch cable to the RJ-45 port on the console cable and the other end of
the patch cable to the RJ-45-to-DB9 adapter (see the following illustration).
Figure 4. Console cable connections
The computer or terminal must run a terminal emulator (for example, SecureCRT,
HyperTerminal, or PuTTY). The console port terminal emulation requirements are
as follows:
• Default baud rate: 9,600 bps
• Character size: 8 characters
• Parity: none
• Stop bits: 1
• Data bits: 8
• Flow control: none
