For more information about the expansion cards that are supported by each blade server type, see this IBM® ServerProven website:
http://ibm.com/servers/eserver/serverproven/compat/us/

I/O adapter cards are installed in the slot in supported servers (such as the x240) as shown in the following figure.

Figure 2. Location of the I/O adapter slots in the IBM Flex System p270 Compute Node


Supported I/O modules

These adapters can be installed in any I/O adapter slot of a supported IBM Flex System compute node. One or two compatible 1 Gb or 10 Gb I/O modules must be installed in the corresponding I/O bays in the chassis. The following table lists the switches that are supported. When connected to the 10 Gb switch or pass-thru module, the internal switch ports operate at 1 Gb speeds.

To maximize the number of usable adapter ports, you might also need to order switch upgrades to enable morel ports as listed in the table. Alternatively, for CN4093, EN4093R, and SI4093 switches, you can use Flexible Port Mapping, which is a new feature of Networking OS 7.8 that allows you to minimize the number of upgrades needed. For more information, see the Product Guides for the switches that are available at this website:
http://www.redbooks.ibm.com/portals/puresystems?Open&page=pg&cat=switches

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

The adapter does not support the IBM Flex System EN6131 40Gb Ethernet Switch I/O module.

The following table shows the connections between adapters that are installed in the compute nodes to the switch bays in the chassis.
