Multi-Switch Interconnect Module for IBM BladeCenter
5
The ports on the CFFh expansion cards in each server are hard wired to specific bays in the switch
modules in each MSIM. Table 4 lists the mapping of expansion card ports to the I/O bays of MSIMs.

Supported I/O modules
Table 5 lists the supported standard form factor I/O modules and the MSIM bays in which they are
supported.
For each of the expansion cards that support the MSIM (see Table 3), the MSIM supports I/O modules in
the left bay, the right bay, or both bays of the MSIM. Table 5 summarizes this support. Because the
supported expansion cards are Ethernet or Fibre Channel only, no SAS or InfiniBand switch modules are
supported in the MSIM.
Note the following explanation when viewing the table:
Right means that the module is only supported in the rightmost I/O slot of the MSIM.
z
Left means that the module is only supported in the leftmost I/O slot of the MSIM.
z
Both means that the module is supported in both the rightmost and leftmost I/O slots.
z
No means that the module is either not supported or not recommended for performance reasons (for
z
example, mixing a 4 Gb FC with an 8 Gb FC).
