* The expansion card can be installed in servers in the BladeCenter S (8886). However, by doing so, you
lose the ability to connect to the BladeCenter S Disk Storage Modules (DSMs). The Ethernet expansion
card goes in the place of the SAS expansion card that is needed to connect to the DSMs. Instead, use the
2/4 Port Ethernet Expansion Card (CFFh), part number 44W4479.
Maximum configuration: Eight Ethernet ports per server
Since BladeCenter servers support both a CFFh expansion card, plus either a CFFv or CIOv card
(depending on the model of the server), you can install up to eight BNT Layer 2/3 Copper or Fiber Gigabit
Ethernet Switch Modules in a BladeCenter H chassis and up to eight BNT Layer 2/3 Copper ESM in a
BladeCenter HT. Figure 4 shows this 8-port solution. All connections between the cards and the switch
modules are internal to the chassis. No wiring is needed.
