  • Page 19: Installing Extended Fabrics

    Chapter Installing Extended Fabrics The installation of Extended Fabrics involves the installation of a license on each switch in the fabric. A license may have been installed in the switch at the factory. If not, contact your switch supplier to obtain a license key. Extended Fabrics licenses are installed using either telnet commands or Web Tools.
