Figure 3 shows how two MSIMs can be installed in the BladeCenter H: one in the space of switch bays 7
and 8, and one in the space of switch bays 9 and 10. The MSIM accepts two supported standard switch
modules and enables a blade server to have up to a total of eight network connections. To connect to the
switch modules in the MSIM, a blade server must have a CFFh-type adapter installed.
