PCI Express card area for cards on the riser card assembly 2

There are three PCI Express card slots on the riser card assembly 2 for installing Ethernet cards or other supported PCI Express cards.

Figure 14. Riser card assembly 2

Notes:

•The slot 1 and slot 2 are supported only in server models with two microprocessors. For server models with one microprocessor, the slot 1 and slot 2 are covered. If you install the second microprocessor in the server, you need to remove the covers that protect the slot 1 and slot 2 before installing any supported cards into the slots.

•If a ThinkServer Host Bus Adapter is available, refer to its user guide for detailed information. The user guide is available for download at:
