Fabric B Fabric B is a dual port, 1 to 10 Gb/sec , quad-lane redundant fabric, supporting I/O module slots B1 and B2. Fabric B currently supports Ethernet, Infiniband, and Fibre Channel modules. To communicate with an I/O module in the Fabric B slots, a blade must have a matching mezzanine card installed in a Fabric B mezzanine card location. Modules designed for Fabric A may also be installed in the Fabric B slots. Fabric C Fabric C is a dual port, 1 to 10 Gb/sec , quad-lane redundant fabric, supporting I/O module slots C1 and C2. Fabric C currently supports Ethernet, Infiniband, and Fibre Channel modules. To communicate with an I/O module in the Fabric C slots, a blade must have a matching mezzanine card installed in a Fabric C mezzanine card location. Modules designed for Fabric A may also be installed in the Fabric C slots. Port Auto-Disablement in Quad-Port Network Daughter Card (M710HD Only) Systems installed with quad-port Network Daughter Card support Port AutoDisablement feature. This feature disables the third (NIC3) and fourth (NIC4) ports of a quad-port Network Daughter Card during system boot, if the corresponding IO module installed in the chassis Fabric A slots do not support quad-port mapping. This behavior is limited to Fabric A slots only and is automatically enabled or disabled depending on the type of IO module installed. NOTE: A quad-port Network Daughter Card must be used with a 48-port switch module (32 internal ports) for all the ports to be active. NOTE: LOM firmware updates are applied only to the enabled ports on a quad-port network daughter card. Table 1-11 provides an overview of the configurations that enable/disable the NIC3 and NIC4 ports of a quad-port Network Daughter Card. About Your System 49
