Chapter 1. Introduction

This Installation Guide provides information and instructions for installing a Lenovo

™

RackSwitch

G8272 (referred to as G8272 throughout this document). For

information about configuration and management of the switch, see the Command

Reference and the product release notes.

The G8272 is a rack-mountable aggregation switch with unmatched line-rate

Layer 2 performance. The G8272 uses a wire-speed, non-blocking switching fabric

that provides simultaneous wire-speed transport of multiple packets at low latency

on all ports.

The G8272 contains forty-eight 10 Gigabit Ethernet (GbE) Small Form Pluggable

Plus (SFP+) ports and six 40 GbE Quad Small Form Pluggable Plus (QSFP+) ports.

The switch also supports legacy 1 GbE connections. The SFP+ ports can be

populated with optical or copper transceivers, or Direct Attach Cables (DACs). The

QSFP+ ports can be populated with optical QSFP+ transceivers or DACs.

The G8272 is 1U rack-mountable in either the horizontal or vertical direction,

depending on your application.

You can manage the switch through the console port, or through a network

connection using Telnet, a Web browser-based interface, or SNMP-based network

management software. For more information, see

page
