Chapter 1. The RackSwitch G7052
Introduction
This Installation Guide provides information about the Lenovo
®
RackSwitch
™
G7052 (referred to as G7052 throughout this document).
The G7052 is a 1U rack-mountable aggregation switch with unmatched line-rate
Layer 2 performance. The G7052 cascades two switching fabrics that provide
simultaneous wire-speed transport of multiple packets at low latency on all ports.
The G7052 contains the following switching ports:
• Forty-eight Gigabit Ethernet (GbE) RJ-45 ports
• Four 10 GbE Small Form Pluggable Plus (SFP+) ports
SFP+ ports can be populated with optical or copper transceiver modules or
Direct-Attach Cables (DACs)
.
The G7052 has rear-to-front airflow. It is 1U in height and can be mounted
horizontally or vertically, depending on your application. Mounting options are
available for a variety of rack systems.
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.

RJ-45 Serial Console Port
The RJ-45 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
one end of the Category 5 patch cable to the RJ-45 serial port on the G7052, then
connect the other end of the patch cable to the RJ-45-to-DB9 adapter (see the
following illustration).
