About This Guide
This guide provides instructions on how to install your Cisco Catalyst Blade Switch 3120 for HP or
Cisco Catalyst Blade Switch 3020 for HP— referred to as the switch module—in the HP c-Class
BladeSystem and how to set up and configure your switch module. The HP c-Class BladeSystem—
referred to as the blade enclosure—supports up to eight Ethernet switch modules, which are installed
in the interconnect bays of the blade enclosure.
This guide also covers management options and troubleshooting help for the switch module.
For details on the numbers, types, and the location of the blade enclosure bays, for additional
information on the blade enclosure system, and for detailed port mapping information, see the
HP BladeSystem enclosure installation poster or the HP BladeSystem enclosure setup and installation
guide at http://www.hp.com/go/bladesystem/documentation.
