Figure 3. IBM BladeCenter H I/O topology showing the I/O paths from CFFh expansion cards
One I/O module must be installed in the chassis for each Ethernet port that you want to use on the
expansion card. Table 4 lists the specific I/O bays in the chassis.
For the Broadcom 10 Gb Gen 2 2-port Ethernet Expansion Card (CFFh), you must install an I/O
module in I/O bays 7 and 9 (that is, two I/O modules).
For the Broadcom 10 Gb Gen 2 4-port Ethernet Expansion Card (CFFh), you must install an I/O
module in I/O bays 7, 8, 9, and 10 (that is, four I/O modules).
