IBM System x3550 M4 22
I/O expansion options
The server supports two PCI slots with different riser cards installed into two riser sockets on the system
planar (one riser socket supports the installation of one riser card). The slot form factors are as follows:
Slot 1: PCIe x16; low profile, half-length

Slot 2: PCIe x16, PCIe x8, or PCI-X; full-height, half-length (PCIe x16 slot requires second processor

to be installed)
Riser 1 supplies slot 1, and riser 2 supplies slot 2. All standard models except for model DDx have two
riser cards installed that provide one PCIe x16 Gen 3 slot and one PCIe x8 Gen 3 slot (features A1HJ and
A1HK). Model DDx has two PCIe x16 slots (A1HJ and A1HL)
You can replace the second riser card with one of the following (or configure one of these riser cards
instead of the second riser card using special bid or CTO), provided a second processor is also installed:
A riser with one PCIe x16 Gen 3 slot (69Y5671, feature A1HL)

A riser with one PCIe x8 Gen 3 slot (69Y5670, feature A1HK

A riser with one PCI-X 64 bit/133 MHz slot (69Y5669, feature A1HM)

The following table lists the PCI riser card options.

Network adapters
The x3550 M4 supports four integrated Gigabit Ethernet ports.
Integrated NICs have the following features:
An Intel I350AM4 chip

Four GbE ports

TCP Offload Engine (TOE) support

Wake on LAN support

802.1Q VLAN tagging support

NIC Teaming (load balancing and failover)

Optionally, two 10 Gb Ethernet ports can be added by installing the a dual-port 10 Gb Ethernet mezzanine
card as listed in the following table. Mezzanine cards use a dedicated connector on the system board and
do not consume a PCI expansion slot.
