4 Lenovo ONIE Quick Start Guide for NE1032T

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 on a 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:

Connecting to the NE1032T

This section describes how to connect to the Lenovo ThinkSystem NE1032T

RackSwitch. For more details about the switch and on how to install the switch

The NE1032T is a 1U GbE switch and it can be rack-mounted in a horizontal

position. The following illustrations show the features on the front and rear panels

of the switch:

Figure 1. NE1032T front panel

Figure 2. NE1032T management panel detail

Figure 3. NE1032T rear panel

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
