following table. Installing two switches means that all ports of the adapter are enabled, which improves
performance and network availability.

* The use of adapter ports 3, 4, 5, and 6 require upgrades to the switches as described in Table 4. The EN4091
Pass-thru only supports ports 1 and 2 (and only when two Pass-thru modules are installed).
** Adapter ports 7 and 8 are reserved for future use. The chassis supports all eight ports but there are currently no
switches available that connect to these ports.
