IBM System x3750 M4 (E5-4600 v2) 19
I/O expansion options
The server supports up to eight PCIe slots, not including the mezzanine LOM slot. Five slots are on the
system board and three are through a riser card. A riser card is standard on some models as shown in the
table below. It is optional on all other models. The use of slots 1 - 5 require processor 2 to be installed.
Table 11 lists the ordering information for the riser cards.
