14 RackSwitch G8296 Installation Guide

© Copyright 2015 Lenovo 15
Chapter 1. The RackSwitch G8296
Introduction
This Installation Guide provides information about the Lenovo
®
RackSwitch
™
G8296 (referred to as G8296 throughout this document).
The G8296 is a 2U rack-mountable aggregation switch used for combining traffic
from multiple high-speed server racks. The G8296 uses a wire-speed, non-blocking
switching fabric that provides simultaneous wire-speed transport of multiple packets
at low latency on all ports.
The G8296 contains the following switching ports:
• Eighty-six 10 Gigabit Ethernet (GbE) Small Form Pluggable Plus (SFP+) ports
which also support legacy 1 GbE connections
• Ten 40 GbE Quad Small Form Pluggable Plus (QSFP+) ports, each of which can
optionally be used as four 10GbE/FCoE SFP+ ports
QSFP+ ports can be populated with optical QSFP+ modules or Direct-Attach Cables
(DACs),
including those that allow the port to be used as four 10 GbE SFP+ ports.
SFP+ ports
can be populated with optical or copper transceiver modules or DACs.
The G8296 is rack-mountable in either the horizontal or vertical direction, depending
on your application. Mounting options are available for a variety of rack systems.
For superior reliability, the G8296 uses redundant, hot-swap power supply modules
and three hot-swap fan modules. Module options are available for either
front-to-rear airflow, or rear-to-front airflow.
You can manage the switch through the local console port, or through a remote
network connection, a Web browser-based interface, or SNMP-based network
management software.
Note: Other features supported on your switch depend on the specific firmware
installed. For more information, see the Application Guide and Command
Reference for your specific switch and its installed firmware.
G8296 Documentation

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).
