64 IBM BladeCenter PS703 and PS704 Technical Overview and Introductionthe BCM5387 is connected to the FSP to provide its connection to the chassis for SOLconnectivity.See 2.8.1, “Server console access by SOL” on page 65 for more details concerning the SOLconnection.MAC addresses for BCM5709S Ethernet portsEach of the two BCM5709S Ethernet ports is assigned one physical MAC address. This isdifferent from the HEA, where each logical port of the HEA had its own MAC address. WhenVIOS (Virtual IO System) is used on the PS703 or PS704 blades, it assigns the MAC virtualaddress that corresponds to the BMC5709S physical addresses as appropriate. Thus thetotal number of required MAC addresses for each PS703 and PS704 base planar is four, twofor FSP and two for Broadcom BCM5709S. On the PS704 SMP planar, only two MACaddresses are needed for 5709S because there is no FSP.Each planar has a label that lists the MAC addresses. The first two listed are those of FSPenet0 and enet1 respectively. The next two listed are for BCM5709S port0 and port1respectively.2.7.6 Embedded USB controllerThe USB controller complex is connected to the Gen1 PCIe x1 bus of the GX++multifunctional host bridge chip as shown in Figure 2-1 on page 38.This embedded USB controller provides support for four USB 2.0 root ports, which are routedto the BladeCenter chassis midplane. However, only two are used: Two USB ports are connected to the BladeCenter Media Tray, providing access to theoptical drive (if installed) and external USB ports to the blade server. The other two ports are not connected. (On other servers, these USB connections are forkeyboard and mouse function, which the PS703 and PS704 blades do not implement.)The BladeCenter Media Tray, depending on the BladeCenter chassis used, can contain up totwo USB ports, one optical drive and system status LEDs.For information about the different media tray options available by BladeCenter model seeIBM BladeCenter Products and Technology, SG24-7523 available from:http://www.redbooks.ibm.com/abstracts/sg247523.htmlThe media tray is a shared USB resource that can be assigned to any single blade slot at onetime, providing access to the chassis USB optical drive and USB ports.Note: The PS703 and PS704 blades do not provide two Host Ethernet Adapters (HEA) asthe previous PS700, PS701, and PS703 blades did. This also means the Integrated VirtualEthernet (IVE) feature is not available on the PS703 and PS704 blades. Broadcom 5709SEthernet ports can be virtualized by PowerVM VIOS software.Note: The PS703 and PS704 blades do not support the KVM function from the AMM. If themouse and keyboard are plugged into the blade center, they are not operational with thePS703 and PS704 blades. You must use SOL via the AMM or an SDMC virtual console toconnect to the blade. See 5.5.6, “Virtual consoles from the SDMC” on page 177 for moredetails.
