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.
