dual-slot mezzanine form factor
Remote Workstation Graphics Card for Dell 14G M-series blade servers
DXM
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:
■ dual-slot: have an extended heat sink and occupy both mezzanine slots in an
M640 blade, the blade can only accommodate one of these cards.
■ 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.
This guide tells you how to install and configure a dual-slot DXM mezz card on a
Dell M640 blade. See Figure 1 for an overview. There is a separate Quick Start
Guide for installing single-slot mezzanine cards.
All kits include a custom mounting bracket with auxiliary power cables.

3. In the VMware vSphere client, locate the ESXi server in the Inventory and
put it in to Maintenance Mode.
4. Shut down the host M640 blade and remove it from the chassis.
5. Open the blade and remove any installed mezzanine cards.
