I/O Expansion Options; Network Adapters - IBM System x3550 M3 Product Manual

I/O expansion options

The server supports up to two PCI Express slots with different riser cards installed into two riser sockets
on the system planar (one riser socket supports installation of one riser card). The slot form factors are as
follows:
Slot 1: Low-profile

Slot 2: Full-height, half-length

Each slot is implemented using a riser card. Standard models have two riser cards installed, which
provide a total of two PCI Express 2.0 x16 slots (one slot per riser card). You can replace each standard
riser with a riser card with one PCI-X 64-bit/133 MHz slot (or configure this riser card instead of the
standard riser using a special bid or configure-to-order):
The following table lists the PCI riser card options.
