HostEngine 4U computer features Intel® Xeon® E5-2600v3 Series (Haswell) dual-processors
with the Intel C612 chipset. HostEngine 4U provides four PCI Express (PCIe) Gen 3.0 x16
expansion slots. Each slot accommodates a full-height, full-length, double-wide GPU or a halfheight, half-length controller such as the Cubix Host Interface Controller (HIC) that connects to
Cubix Xpander products. Each HIC connects to multiple slots within an Xpander Rackmount 8
or other Xpander products.
By connecting HostEngine to GPU-Xpander Rackmount 8, you can add eight double-wide
GPUs such as NVIDIA® Quadro M5000 or M6000 to the HostEngine 4U computer for running
Autodesk® 3ds Max or Bunkspeed® Shot with NVIDIA iray running on Linux or Microsoft®
Windows®. You can also run BlackMagic Design® DaVinci Resolve® for Linux on HostEngine
4U computer. Connecting to Xpander Rackmount 8 also enables you to connect to GPU
Compute Engines such as NVIDIA or AMD GPUs for HPC applications, virtual desktop projects
or multiple Intel Xeon Phi coprocessors for parallel processing.
When installing a HIC in HE4U, make sure you seat it in one of the PCIe Gen 3 x16 slots, which
are numbered CPU1 Slot2, CPU1 Slot 4, CPU2 Slot 6 and CPU2 Slot 8. For double-wide
accelerators like NVIDIA Quadro Series or AMD Firepro W Series, use these four slots as well.
If you add a single-wide display controller like AMD Firepro W2100 / W4100 or NVIDIA Quadro
K4200 for connecting one or more 4K / UHD displays, and the PCIe Gen 3 x16 slots are
occupied, use CPU1 Slot 10.
HostEngine 4U supports one to four 2.5-inch SATA 3 solid-state drives (SSDs) to boot the
operating system (OS). HostEngine 4U also accommodates PCIe flash / SSDs. Install PCIe
flash or SSD cards in CPU1 Slot 10 and / or CPU2 Slot 11, if available. See page 4 for details.

Connections, Controls and Indicators
Connections
On the rear panel, HostEngine provides four USB 2.0 ports, two Gbps Ethernet ports, a COM
port and an IPMI 2.0 GbE port. The AC power receptacle is also on the rear panel.
HostEngine also provides access for Cubix HICs that connect to GPU-Xpander Rackmount 8 or
other Xpander enclosures using external PCIe x16 cables, if needed. With these connections,
you can mount HostEngine immediately above or below GPU-Xpander Rackmount 8. You can
also install PCIe cards inside HostEngine 4U. For example, install 4 x full-length, full-height,
double-wide GPUs inside HostEngine 4U.

Controls
The front panel provides the power on/off button and
the reset button. Pressing and releasing the power
button during operation will provide a graceful
shutdown of the operating system. Pressing and
holding the power button for 4 seconds or more forces
HostEngine to power off. See the image at the right.
Indicators
Indicators (LEDs) for power (steady green), hard drive activity (flashing green), reset (flash
green once), management (steady green) and identification (steady blue if enabled) are also on
the front panel.
Install HostEngine in a Rack Mount Cabinet
Cubix ships HostEngine with the slide mounts installed on the enclosure.
Within packaging, you will find four brackets that
mount within your rack mount cabinet as well as
screws, nuts and G-nuts for use in mounting
HostEngine. See the image at right.
Mount HostEngine close enough to GPU-Xpander
Rack Mount 8 so that the standard 2meter cables
will reach. Mount GPU-Xpander Rack Mount 8
enclosure immediately above or immediately
below HostEngine in the rack mount cabinet. For
this procedure, use a Philips #2 screwdriver, a flat-

1. Shut down HostEngine normally.
Warning
Before you lift a HostEngine into place, ask for assistance.
2. Disconnect all data and power cables.
3. Remove the two slide mounts—one slide mount
from each side of the HostEngine enclosure. To
release each slide mount, slide it toward the rear of
the enclosure until it stops. Press the catch to
release and remove the slide mount as you can see
in the image at the right.
4. Mount the HostEngine mounting brackets and slide mounts in your cabinet. Allow vertical
space for 2U or 4U as appropriate for your enclosure.
5. Mount the front and rear mounting brackets in the
left side of your cabinet. Make sure all four line up
so that HostEngine is level within the cabinet. See
the image at the right.
6. Mount each of the two sliders into the front and rear
mounting brackets (Part # S18500A) and slider
assembly with the bolts and G-nuts provided in the
packaging. Use the Philips #2 screwdriver and the
3/8” wrench or socket to secure snugly but not
tightly each slider to the front and rear mounting brackets. Check to make sure the mounting
brackets and slide rails are level from front to rear before tightening the screws and nuts.
Align the front of the slider with the front of the cabinet.
7. Repeat the process for the other two front and two rear mounting brackets and slider
assembly on the right side of the cabinet.
8. Check to make sure that the slide rails are level,
both from front to back and from right to left. Once
you’re sure the slide rails are level, you’re ready
to tighten the mounting screws. See the image at
the right.
9. Tightly secure the screws holding the sliders to
the front and two rear mounting brackets on each side of the cabinet.
10. Extend the slide rails almost all the way out the front of the cabinet.
11. Lift the HostEngine, line it up carefully and slide it into place. Before lifting the HostEngine
into place, ask for assistance.
12. Try sliding the HostEngine in and out slightly to make sure it moves freely.
13. Connect the AC power cords into the HostEngine rear receptacle.
14. Connect the PCIe x16 external cables to GPU-Xpander Rack Mount 8.
15. Power up HostEngine.

2. Remove the power cord.
3. Gently pull the HostEngine toward you a foot or so.
4. Remove the screws holding in place the HostEngine front top cover, remove the top cover
and the top end-bracket panel and set them aside.
5. Add, remove or replace the memory, HICs or other cards, making sure to seat each firmly in
the socket or slot, secure the end bracket screws and to connect aux power cables, if
necessary.
6. Replace the HostEngine front top cover and replace the screws holding it in place.
7. Gently slide HostEngine back in place.
8. Connect the AC power cord into the HostEngine rear receptacle.
