Remote Workstation solutions for Dell FX2s FC630/FC640 blade servers
Quick Start Guide
For Health and safety information, refer to the sheet LS-AHKL-0001.
The FX400 is an expansion module for the Dell PowerEdge FX2 chassis.
Each FX400 CoreModule contains one NVIDIA T4 PCIe card. The T4 is a high
utility GPU that accelerates a wide range of modern applications such as
machine learning, deep learning, and virtual desktops. The T4 is optimised for
maximum utility in the cloud and enterprise data centers to deliver superior
scalability, reliability and performance.
There may be different ways to configure, depending on use case. As well as
explaining the basic installation of the FX400, this guide gives one setup example
of how to use an FX400 CoreModule with an FC640 to support virtual desktops.

Assign two module slots to one blade (default)

Each FX400 CoreModule contains one NVIDIA T4 PCIe card that maps to a blade
installed in the top/bottom position in the same side at the front of the FX2s
chassis as shown in Figure 1.
Figure 1: Four blade configuration example
In Figure 1 the FX400 CoreModules in positions PCIe1 & PCIe2 at the rear left
hand side (LHS) connect with a blade in the bottom Compute 4 position on the
right hand side (RHS) at the front.
The second pair (PCIe3 & PCIe4) connect to the blade in the top Compute 2
position on the same side.
The third pair (PCIe5 & PCIe6) connect to the bottom Compute 3 position on the
front LHS.
The fourth pair (PCIe7 & PCIe8) connect to Compute 1 in the top position on the
front LHS.

Assign four module slots to one blade

If only one blade is used on half of the chassis, the space below can be empty,
contain a storage sled, or a compute sled with no PCIe expansion requirement.
In Figure 2, four FX400 CoreModules connect with a single blade in the top
Compute position. So Compute 1 connects to PCIe5, 6, 7 & 8 on the RHS (rear).
Compute 2 connects to PCIe 1, 2, 3, 4 on the LHS (rear).

How to select the mapping for four module slots to one blade

! Caution:
This is only possible when all sleds or blades are powered down.
1 Login to the CMC with the IP address, username and password.
2 Select PCIe Overview from the left-hand menu and click the Setup tab.
3 Make sure the Enable PCIe Slot Reassignment box is checked. See
Note: This selection is automatic when a storage sled is installed in the chassis
slots Compute 3 or Compute 4, reassigning the slot below to the slot above.
Figure 3: Reconfigure the iDRAC for alternative slot reassignment

Prepare the blades in the FX2s chassis

1 For a new install, power down all the blades.
2 For an existing configuration:
a). shut down or migrate all VMs hosted by the blades;
b). in the VMware vSphere client, locate the ESXi server in the Inventory and
put it in to Maintenance Mode;
c). power down any blades that will connect to the FX400 CoreModule.
3 Remove any Dell Single slot PCIe modules that occupy the slots where you
will install the FX400 CoreModule.

Install a FX400 CoreModule module in a PCIe slot

The FX400 CoreModule module installs easily into the rear of the FX2s chassis
into one of the eight slots of the expansion bay.
! Caution:
Always use anti-static handling procedures, such as wearing a
wrist-strap, before handling the FX400 CoreModule.
1 Remove all packaging and the connector protector from the module.
2 Decide which is the correct position to install the module(s).
Note: Make sure you install the FX400 CoreModule module in the correct PCIe
slot of the expansion bay for your configuration. Refer to
Figure 3.
Figure 1 and Figure 2.
