One I/O module must be installed in the chassis for each 4X InfiniBand port that you wish to use on the

expansion card. The specific I/O bays in the chassis are listed in Table 4. For the 2-Port 40 Gb InfiniBand

Expansion Card (CFFh), you should install an I/O module in I/O bays 7/8 and 9/10 (that is, two I/O

modules, each of them occupies two adjacent high-speed slots).
