: X2 modules have duplex SC connectors. An SC-to-LC fiber cable is required to connect to a SFP+
transceiver with duplex LC connectors.
For Ethernet Switch Modules with SFP+ or X2 ports see their respective IBM Redbooks at-a-glance
guides to locate the transceivers supported. Review Table 6 for guidance on how to connect the Ethernet
Switch Module to the B48Y.
For optimal BladeCenter performance, the Intelligent Copper Pass-Thru Module (44W4483) can be used
to directly connect the internal blade server NIC mezzanine cards to the B48Y, providing maximum,
non-oversubscribed performance while eliminating a hop in the network and reducing latency.
