DXM single-slot mezzanine form factor
Remote Workstation Graphics Card for Dell 14G M-series blade servers
Quick Start Guide
The DXM product is a range of KVM extender graphics host cards in a mezzanine
slot form factor ('mezz cards') for Dell M-series blade servers.
Dual and single-slot form factor versions of the DXM are available:
single-slot: only occupy a single mezzanine slot. You can install them in pairs
■
or in tandem with a different card. Ideal for space constrained installations.
dual-slot: for higher power GPUs. Occupy both mezzanine slots in an M640
■
blade, the blade can only accommodate one of these cards.
This guide tells you how to install and configure a single-slot DXM mezz card on
a Dell M640 blade. See Figure 1 for an overview.
All kits include a custom mounting bracket with auxiliary power cables. An
interconnect PCB is only shipped with octal configurations.

Prepare the blade

Important! Always use anti-static handling procedures to handle a DXM card
or to work on the inside of a blade. Keep liquids away from the area.
1. If the blade is not in a chassis then go to Step 4. If it is in a chassis, stop all
VM activity on the blade. Shut down or migrate all VMs hosted by the blade.
2. In the VMware vSphere client, locate the ESXi server in the Inventory and
put it in to Maintenance Mode.
3. Shut down the host M640 blade and remove it from the chassis.
4. Open the blade and remove any installed mezzanine cards.

Remove the Dell mounting bracket

1. Remove the screw on the Dell mezzanine card mounting bracket and retain.
2. Remove the two screws from the Network Daughter Card (NDC) and retain.
3. Remove together the mounting bracket and NDC from the enclosure.
4. Discard this mounting bracket and install again the NDC with the two screws.

Install the mezzanine support bracket (part A)

Important! The bracket only fits one way in the blade.
1. Move the support bracket (part A) into the blade so that the locating pins on
the bracket align with the two blade pin recesses. See
Figure 2: Align pins with the blade pin recesses
2. Move the bracket (part A) downwards. As the pins engage with the recesses,
make sure that the sprung leg engages under the NDC. See
Figure 3: Move the support bracket (part A) into position
3. Install the retaining screw into the bracket.

Connect the power cable

Important! The DXM card can install in one of two positions and requires
either a short power cable for mezzanine slot A, or long for mezzanine slot B.
1. Select the correct power cable, long for mezzanine slot B, short for
mezzanine slot C or a dual cable if installing two DXMs .
2. Push the connector on the power cable through the square hole in the
bracket (part A) and into the socket on the motherboard. See
Important! Make sure the alignment feature aligns with the socket.
