Riser 1 supplies slot 1, and riser 2 supplies slots 2 and 3. All standard models have one riser card (Riser
1) installed, which provides one low profile PCIe x16 Gen 3 slot (riser option part number 00KA061). You
can replace the first riser card or add a second riser card with the riser card options that are listed in the
following table (or configure these riser cards to be factory-integrated using special bid or CTO).

Note: The HDD Rear Kit (00KA058; see the "Internal storage" section) is installed in place of the PCIe
slots 1 and 2, and it includes a special riser that provides PCIe 3.0 x16 slot 3. No other riser cards can be
used when the HDD Rear Kit is installed.
The x3550 M5 Thermal Kit, part number 00KA059, contains two fans. It provides the seventh and eighth
system fans needed for the following options when only one processor is installed:
Intel X540 ML2 Dual Port 10GbaseT Adapter for System x

QLogic 8200 Dual Port 10GbE SFP+ VFA for System x

The x3550 M5 Thermal Kit is not needed if two processors are installed, because the second processor
includes these fans.
The COM Port Bracket, part number 00KA161, is used for mounting the external serial port on the rear of
the x3550 M5. This option includes the bracket and the cable. The COM Port option is mounted in place
of the PCIe slot 3, and only PCIe slots 1 and 2 remain available.
The following table lists the x3550 M5 Thermal Kit and COM Port Bracket part numbers.
