module, the internal switch ports will operate at 1Gb speeds.
To maximize the number of adapter ports usable, you may also need to order switch upgrades to enable
additional ports as listed in the table. Alternatively, for CN4093, EN4093R, and SI4093 switches, you can
use Flexible Port Mapping, a new feature of Networking OS 7.8, that allows you to minimize the number of
upgrades needed. See the Product Guides for the switches for more details:

The table also specifies how many ports of the adapter are supported once the indicated upgrades are
applied. Switches should be installed in pairs to maximize the number of ports enabled and to provide
redundant network connections.
