IBM Flex System EN4091 10Gb Ethernet Pass-thru** 88Y6043 A1QV 3700

* Upgrade 1 is required for the EN2092 and EN4093 to use all four ports on the adapter.

** The EN4091 Pass-thru has only 14 internal ports and so only supports ports 1 and 2 of the adapter.

Installing two switches means that all four ports of the adapter are enabled. However, the use of all four

ports also requires Upgrade 1 of the supported 10 GbE and 1 GbE switches to be applied. Upgrade 1, as

listed in the preceding table, enables 28 internal ports on each switch. The EN4091 Pass-thru has only 14

internal ports and so only supports ports 1 and 2 of the adapter. The following table shows the

connections between adapters installed in the compute nodes to the switch bays in the chassis.

* 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).
