Riser 1; Riser 2 - IBM System x3850 X5 Implementation Manual

4.10.1 Riser 1

In standard x3690 X5 models, riser slot 1 has the 2x8 riser card installed (60Y0329, feature
9285) which has the following slots:
Slot 1, PCIe 2.0 x8 full height, full length slot
Slot 2, PCIe 2.0 x8 full height, half length slot
The 2x8 riser can be replaced by another riser with one PCIe 2.0 x16 slot, which is either a
full-length slot or a 3/4-length slot, as listed in Table 4-31. This x16 slot is suitable for graphics
processing unit (GPU) adapters. Additional power for the adapter is available from an
onboard power connector if needed.
Table 4-31 lists the riser card options for Riser 1. Only one of the risers listed in the table can
be installed in the server at a time.

a. The 2x8 riser card is standard in all x3690 X5 models, including 7148-ARx.
b. The 1x16 full-length riser cannot be used if the memory mezzanine is installed in the server.

4.10.2 Riser 2

Riser slot 2 has the 3x8 riser card installed in all standard models, except for model 7148-ARx
(see 4.3, "Models" on page 124), and contains the following slots:
Slot 3, PCIe 2.0 x8 low profile adapter.
Slot 4, PCIe 2.0 x4 low profile adapter (x8 mechanical).
Slot 5, PCIe 2.0 x8 low profile adapter. The Emulex 10Gb Ethernet adapter is installed in
this slot if the adapter is part of the server configuration.
Full-length adapters: Full-length adapters cannot be installed in any slots if the memory
mezzanine is also installed. Instead, adapters up to 3/4 length are supported.
Table 4-32 lists the option.

a. The 3x8 riser card is standard in all x3690 X5 models,
Note: The Emulex 10GbE Virtual Fabric Adapter that is standard in most models is
installed in slot 5. See 4.10.3, "Emulex 10Gb Ethernet Adapter" on page 166 for details of
the adapter.
