* Ports 3 and 4 require Upgrade 1 of either the EN2092 1Gb or EN4093 10Gb switch. The EN4091 Pass-
thru only supports ports 1 and 2 (and only when two I/O modules are installed).
The connections between the adapters installed in the compute nodes to the switch bays in the chassis are
shown diagrammatically in the following figure. The figure shows both half-wide servers, such as the x240
with two adapters, and full-wide servers, such as the x440 with four adapters.
