Dell Chassis Management Controller Version 2.10 for PowerEdge FX2 and FX2s User's Guide

The PCIe reassignment feature enables you to map PCIe slots assigned to compute sleds in the lower bays to compute sleds in the upper bays.

You can enable or disable the PCIe reassignment option using CMC web interface, CMC WSMan, or RACADM. You must have the chassis configuration privilege to configure or modify the reassignment settings. Power off all compute sleds in the chassis before modifying the reassignment settings. When the compute sleds are powered on after the reassignment changes, the slots assigned to the compute sleds in the lower bay earlier, are mapped to corresponding compute sleds in the upper bay. Following are some examples for PCIe reassignment:

• PCIe reassignment in full-width (FW) FC830:
  • PCIe slots mapped to FW sled-3 (PCIe slots 1 through 4) are reassigned to sled–1. Sled-1 now maps to PCIe slots 1 though 8.
• PCIe reassignment in half-width (HW) FC630:
  • PCIe slots mapped to HW sled-3 (PCIe slots 5 and 6) are reassigned to sled-1. Sled-1 now maps to PCIe slots 5 through 8.
  • PCIe slots mapped to HW sled-4 (PCIe slots 1 and 2) are reassigned to sled-2. Sled-2 now maps to PCIe slots 1 through 4.
• PCIe reassignment in quarter-width (QW) FC430:
  • PCIe slot mapped to QW sled-3a (PCIe slot 6) is reassigned to sled-1a. Sled-1a now maps to PCIe slots 6 and 8.
  • PCIe slot mapped to QW sled-3b (PCIe slot 5) is reassigned to sled-1b. Sled-1b now maps to PCIe slots 5 and 7.
  • PCIe slot mapped to QW sled-3c (PCIe slot 2) is reassigned to sled-1c. Sled-1c now maps to PCIe slots 2 and 4.
  • PCIe slot mapped to QW sled-3d (PCIe slot 1) is reassigned to sled-1d. Sled-1d now maps to PCIe slots 1 and 3.
