Configuration notes:
The 1 CPU Riser 2 options (feature codes A5AC and A5AE) are supported only in configurations with
one processor. If two processors are selected, these options cannot be used.
If the FHHL x16 Riser 2 option (feature code A5AD) is selected, the x16 Riser 1 option (feature
code A5AG) cannot be used.
If both ML2 Riser 1 (feature code A5AH) and FHHL x8 or x16 Riser 2 option (feature code A5AE
or A5AD) are selected, one of the following ML2 network adapters is allowed for selection:
Broadcom NetXtreme II ML2 Dual Port 10GbaseT (part number 00D2026)
Broadcom NetXtreme II ML2 Dual Port 10GbE SFP+ (part number 00D2028)
Emulex VFA5 ML2 Dual Port 10GbE SFP+ Adapter (part number 00D1996)
Intel X540 ML2 Dual Port 10GbaseT Adapter (part number 00D1994)
Intel I350-T4 ML2 Quad Port GbE Adapter (part number 00D1998)
If the FHHL x8 or x16 Riser 2 options (feature codes A5AD and A5AE) are selected, the Mellanox
ConnectX-3 Pro ML2 2x40GbE/FDR VPI Adapter (part number 00FP650) cannot be used.
The HDD Rear Kit (00KA058; see Internal storage) is installed in place of the PCIe slots 1 and 2; it
includes a special riser that provides PCIe 3.0 x16 slot 3, and no other riser cards can be used.
The COM Port Bracket listed in the following table is used for mounting the external DB-9 serial port on the
rear of the System 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.
