The 10 Gbps ports on the optional 4-port 10 GbE Interface Module (81Y1455) are typically used for
uplinks to the rest of the Ethernet/IP network. These ports can be connected to servers as needed. 10
Gbps Ethernet connectivity is not standard in most System x servers, and a 10 GbE NIC or 10 GbE CNA
must be installed. Only the IBM System x3850/3950 X5 series (except for the ARx model) come standard
with a customized Emulex Virtual Fabric Adapter. Table 7 lists the 10 GbE adapters that are available for
IBM System x servers.

The Brocade 10Gb CNA [42C1820], QLogic 10Gb CNA [42C1800], and Emulex Virtual Fabric Adapter
[49Y4250] each have two SFP+ ports and can be connected to the B48Y using:
The adapter’s supported 10GBASE-SR SFP+ transceiver connected to the B48Y 10GBASE-SR
z
SFP+ transceiver [69Y0389] over multi-mode fiber cable
The Direct Attach SFP+ Active TwinAx copper cables listed in Table 4

The NetXtreme II 10 GigE Express Fiber SR Adapter [42C1790] has a single integrated 10GBASE-SR
optic. This port can be connected to the B48Y 10GBASE-SR SFP+ transceiver [69Y0389] over
multi-mode fiber cable.
Connectivity to IBM BladeCenter
IBM BladeCenter Ethernet Switch Modules are available with 1 Gbps and 10 Gbps Ethernet uplinks. The
B48Y can be deployed as an aggregation switch to provide connectivity between down-stream 1 Gbps
Ethernet Switch Module,s but would not typically be used to aggregate connections from 10 Gbps
Ethernet Switch Modules.
