Network Information

You can configure your I/O switch modules using:

• CMC web-based interface.

NOTE:

The default IP address for the CMC is 192.168.0.120.

• CMC CLI using serial console redirection.

• Direct access to the I/O module serial port (if supported).

• I/O module default IP address (if supported).

I/O Connectivity

The enclosure supports three layers of I/O fabric, selectable between combinations of Ethernet, fibre-channel, and Infiniband modules.

You can install up to six hot-swappable I/O modules in the enclosure, including fibre channel switches, fibre-channel pass-throughs,

Infiniband switches, Ethernet switches, and Ethernet pass-through modules.

General I/O Module Configuration Guidelines

• If an I/O module is installed in Fabric B or Fabric C, at least one blade must have a matching mezzanine card installed to support data

flow to that I/O module.

• If a blade has an optional mezzanine card installed in a Fabric B or Fabric C card slot, at least one corresponding I/O module must be

installed to support data flow to that fabric.

• Modules may be installed in Fabrics B and C independently (you do not need to install modules in Fabric B before installing modules in

the Fabric C slots).

• Slots A1 and A2 only support Ethernet I/O modules. This fabric type is hardset to Ethernet for these slots and cannot support fibre

channel, Infiniband, or other fabric type modules.

• Fabrics A, B, and C can support Ethernet fabric-type modules.

• To enable switch configuration prior to blade imaging, I/O modules are allowed to power-up before a blade is inserted in the enclosure.

Fabric A

Fabric A is a redundant Gb Ethernet fabric, supporting I/O module slots A1 and A2. The integrated Ethernet controllers in each blade

dictate Fabric A as an Ethernet-only fabric.

NOTE:

Fabric A supports KR (10 Gbps standard).

NOTE: Modules designed specifically for Fabric B or Fabric C cannot be installed in slots A1 or A2, as indicated by the

color-coded labeling on the faceplate of each module.
