Configuring The I/O Modules
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.
