IBM Flex System Fabric CN4093 10Gb Converged Scalable Switch 3
The base switch and upgrades are as follows:
00D5823 is the part number for the physical device, which comes with 14 internal 10 GbE ports

enabled (one to each node bay), two external 10 GbE SFP+ ports enabled to connect to a top-of-rack
switch or other devices, and six Omni Ports enabled to connect to either Ethernet or Fibre Channel
networking infrastructure, depending on the SFP+ cable or transceiver used.
00D5845 (Upgrade 1) can be applied on the base switch when you need more uplink bandwidth with

two 40 GbE QSFP+ ports that can be converted into 4x 10 GbE SFP+ DAC links with the optional
break-out cables. This upgrade also enables 14 additional internal ports, for a total of 28 ports, to
provide more bandwidth to the compute nodes leveraging 4-port expansion cards.
00D5847 (Upgrade 2) can be applied on the base switch when you need more external Omni Ports

on the switch or if you want additional internal bandwidth to the node bays. The upgrade will enable
the remaining six external Omni Ports, plus 14 additional internal 10 Gb ports, for a total of 28 internal
ports, to provide more bandwidth to the compute nodes leveraging four-port expansion cards.
Both 00D5845 (Upgrade 1) and 00D5847 (Upgrade 2) can be applied on the switch at the same time

to allow you to leverage six ports on an eight-port expansion card, and to utilize all external ports on
the switch.
The following table lists supported port combinations on the switch and required upgrades.
