3Configuring The I/O ModulesNetwork InformationYou 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 ConnectivityThe enclosure supports three layers of I/O fabric, selectable between combinations of Ethernet, fibre-channel, andInfiniband modules. You can install up to six hot-swappable I/O modules in the enclosure, including fibre channelswitches, 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 cardinstalled 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 correspondingI/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 Bbefore 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 andcannot 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 isinserted in the enclosure.Fabric AFabric A is a redundant Gb Ethernet fabric, supporting I/O module slots A1 and A2. The integrated Ethernet controllers ineach 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 bythe color-coded labeling on the faceplate of each module.35
