• Without a license, the maximum number of PCIe slots that maybe mapped to a half-height server is
two. If a full-height server is installed you can map two PCIe slots to the upper server slot and two to
the lower (extended) server slot, for a total of four PCIe slots per full-height server.
• You can map the server slots to any of the 8 PCIe slots.
• A full-height server has both upper and lower mezzanines populated. Else, during POST will stop
when the <F1> or <F2> is displayed on the page for you to press any one of the keys.
• For full-height servers you can map a maximum of two PCIE slots to upper and two to lower
mezzanines. By default, all PCIe mappings to server slot 3 will go to the lower mezzanines.
• Server slot number is displayed as Slot-01, Slot-02, and so on. For a full-height server, the slot name is
displayed as Ext. of Slot-01, Ext. of Slot-02, and so on.
• If you select the host name, then the host name is displayed instead of the slot name.

Managing PCIe Slots Using RACADM
You can assign or unassign a PCIe slot to a server by using the RACADM commands. Some of the
commands are given here. For more information about the RACADM commands, see the Chassis
Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide available at
dell.com/support/Manuals.
• To view the current assignment of PCIe devices to servers, run the following command:
racadm getpiecfg -a
• To view the properties of PCIe devices by using FQDD, run the following command:
racadm getpciecfg [-c <FQDD>]
For example, to view the properties of PCIe device 1, run the following command.
racadm getpciecfg -c PCIE.ChassisSlot.1
• To assign a PCIe adapter slot to server slot, run the following command:
racadm setpciecfg assign [-c <FQDD>] [i <server slot>]
• For example, to assign PCIe slot 5 to server slot 2, run the following command.
racadm setpciecfg assign -c PCIE.ChassisSlot.5 -i 2
• To unassign a PCIe slot 3 from a server, run the following command:
racadm setpciecfg unassign -c pcie.chassisslot.3
PCIe Power Ride-Through
Newly assigned PCIe cards in CMC VRTX must be discovered and initialized before a server node is
powered on. The discovery and initialization process involves the following:
• Inventory and discovery of installed cards
• Preparing a PCIe card for exposure to a server module
• Preparing multiple cards for configuration by server BIOS
• Initializing all cards prior to blade node power-on
