IBM System x3690 X5 20Network adaptersThe x3690 X5 offers two integrated Gigabit Ethernet ports, based on the Broadcom BCM5709C controller.Some models also have an Emulex 10Gb Dual-port Ethernet Adapter (feature 1648) installed as standardin Slot 5. See Tables 2 and 3 for specifics. This adapter is functionally identical to the Emulex 10Gb VirtualFabric Adapter for IBM System x, 49Y4250. The difference is that the Emulex 10Gb Dual-port EthernetAdapter has a longer edge connector meaning that the card can only be installed in this server. Fortechnical details about this card, see theEmulex 10Gb Virtual Fabric Adapter for IBM System x,TIPS0762, at-a-glance guide available at http://www.redbooks.ibm.com/abstracts/tips0762.html.The following table lists additional supported network adapters.Table 22.
