The server offers the up to five PCI Express 2.0 slots through two riser slots. The slots available depend
on the riser cards used. None of the slots are hot-swap. All slots are available regardless of whether one
or two processors are installed.
Riser slot 1 can accept one of the riser cards listed in the following table, however, all standard models
have the 2x8 riser card installed. This card provides the following PCIe 2.0 slots:
Slot 1, PCIe 2.0 x8 full height, half length slot
Slot 2, PCIe 2.0 x8 full height, half length slot
For CTO customers, the 2x8 riser can be replaced by another riser with one PCIe 2.0 x16 slot, either a
full-length slot or a 3/4-length slot, as listed in the following table. This x16 slot is suitable for graphics
processing unit (GPU) adapters. Additional power for the adapter is available from an on-board power
connector if needed. Note that you cannot install the full-length riser (60Y0337) if the memory mezzanine
is installed.

Riser slot 2 has the 3x8 riser card installed in all standard models, except for model 7148-ARx. For model
ARx, it can be ordered using 60Y0366. See the following table. This riser card has the following three
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.
The 3x8 riser card also contains two USB ports, one of which supports the use of an embedded
hypervisor key with VMware ESXi installed on it. The other USB port is not used.

: 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.
