Managing Fabrics

The chassis supports two fabric types: Fabric A1 and Fabric A2, which are used by the two I/O Modules,

and are always connected to the on-board Ethernet adapters of the servers.

NOTE: In the PowerEdge FX2s chassis, fabrics B and C are the PCIe connection to the PCIe

Extension cards.

Following IO Modules are supported:

• 1GbE pass-through

• 10GbE pass-through

• I/O Aggregator

Both the Fabrics support only Ethernet. Each server IO adapter ( LOM) can have either two or four ports

depending on the capability. The mezzanine card slots are occupied by PCIe extension cards that are

connected to PCIe cards (and not to IO modules).

NOTE: In the CMC CLI, the IOM is referred to by the convention, switch.

Monitoring IOM health

For information about monitoring IOM health, see Viewing Information and Health Status of the IOM.

Configuring network settings for IOM

You can specify the network settings for the interface used to manage the IOM. For Ethernet switches,

the out-of-band management port (IP address) is configured. The in-band management port (that is,

VLAN1) is not configured using this interface.

Before configuring the network settings for the IOM, make sure the IOM is turned on.

To configure the network setting of IOM in Group A, you must have the Fabric A Administrator privileges.

NOTE: For Ethernet switches, the in-band (VLAN1) and out-of-band management IP addresses

cannot be the same, or cannot be on the same network. This results in the out-of-band IP address

in being not set. See the IOM documentation for the default in-band management IP address.

NOTE: Do not configure I/O module network settings for Ethernet pass-through and Infiniband

switches.
