LASER SAFETY
The DXP4-M may be ed with SFP network
modules that contain Class 1 lasers. The SFP
module emits invisible radiaon which can cause
harm if installed or serviced incorrectly. Follow
the guidelines below:
Warning: Class 1 laser product.
Warning: Invisible laser radiaon can be
emied from the aperture of the SFP port
when no bre is connected. To avoid exposure
to laser radiaon, do not stare into open
apertures.
Warning: Only trained and qualied personnel
may install, replace, or service this equipment.

FCC Noce
This device complies with part 15 of the FCC Rules. Operaon is subject to the following
two condions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operaon.
Title 47, Part 15 (47 CFR 15) of the Federal Communicaons Commission (FCC) Rules and
Regulaons establishes Radio Frequency (RF) emission limits for unlicensed emissions to
provide an interference-free radio frequency spectrum. Many electronic devices, including
computers, generate RF energy incidental to their intended funcon and are, therefore,
covered by these rules. These rules place computers and related peripheral devices into
two classes, A and B, depending upon their intended installaon. Class A devices are those
that may reasonably be expected to be installed in a business or commercial environment.
Class B devices are those that may reasonably be expected to be installed in a residenal
environment (personal computers, for example). The FCC requires devices in both classes to
bear a label indicang the interference potenal of the device as well as addional operang
instrucons for the user. A label on the device shows which class (A or B) the equipment falls
into. Class B devices have an FCC logo or FCC ID on the label. Class A devices do not have an
FCC logo or FCC ID on the label.
The DXP4 has been tested and found to comply with the limits for a Class A digital device,
as dened by Part 15 of the FCC Rules. These limits are designed to provide reasonable
protecon against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instrucons, may cause harmful interference
to radio communicaons. Operaon of this equipment in a residenal area is likely to cause
harmful interference, in which case the user will be required to correct the interference at
their own expense.
EU Noce
• This product complies with EMC Direcve 2014/30/EU and the Low Voltage Direcve
2014/35/EU. Conformity is shown by compliance with the applicable requirements of
the following documents:
• EN 55032 (CISPR 32) (Class A) - Emissions
• EN 55024 (IEC 61000-4-2,3,4,5,6,8,11) - Immunity
• EN 61000-3-2 (IEC 61000-3-2) - Power Line Harmonics
• EN 61000-3-3 (IEC 61000-3-3) - Power Line Flicker
• EN 60950 (IEC 60950) - Product Safety
Cauon:! This equipment is compliant with Class A of CISPR 32. In a residenal environment
this equipment may cause radio interference.

Before you start 1
1. Before you start
This manual is for the Amulet Hotkey DXP4 and DXP4-M Remote
Workstaon Graphics Cards. Before you install the DXP4 or
DXP4-M, make sure you read the following informaon.
The Amulet Hotkey DXP4 is a PC-over-IP (PCoIP®) host with
an integrated quad-video GPU. It is an ideal host soluon for
remote desktop applicaons that require pixel perfect video
across mulple monitors.
1.1 DXP4 models
The DXP4 is a PCI express (PCIe) card available with the following
variaons:
1.1.1 Network soluons
DXP4: The standard card has a single RJ45 network port;
DXP4-M: This model has a single network port that accepts
either a ber or copper SFP module (see 1.3 and Figure 1).
1.1.2 Thermal soluons
Both the DXP4 and the DXP4-M are available for dierent PC,
server or Workstaon cooled environments:
• Acve Thermal Soluon: the card is cooled via an on-board
fan;
• Passive Thermal Soluon: the card uses a large heatsink and
relies on a temperature-controlled environment provided by
the PC or server.
Important! Make sure you choose the correct card type for
your enclosure.
Note: Some GPUs are not available in both thermal soluons.
See 10. Technical specicaons for more details. Both thermal
soluons are installed and congured in the same way.
1.1.3 Terminology
The general term ‘host card’ is used throughout this manual to
describe all network and thermal variants.
1.2 Auxiliary power requirements
Important! The host card may require an auxiliary power
connecon from the power supply depending on the GPU
power requirements and the power supply from the mother-
board. See 3.3.1 Connect auxiliary power (Oponal).
1.3 SFP modules
Amulet Hotkey can provide a range of suitable SFP modules,
including 1Gbps and 100Mbps ber SFP modules for single or
mul-mode ber and copper SFP modules with RJ45 connectors.
See the Amulet Hotkey SFP Modules Datasheet for details of
currently available modules.
Be aware that SFP modules have diering specicaons, and
the distances over which they can drive a signal can vary. This
especially applies to ber SFP modules.
Important! The DXP4-M only supports certain models of SFP
module. If in doubt, contact Technical Support for advice.
1.4 IP and MAC addresses
Before you set up a host card, make a note of these details:
• MAC and IP address of the remote PCoIP host;
• MAC and IP address of the zero client.
You will nd the MAC address informaon wrien on the
underside of the zero client and on the conguraon record/
serial number label of the remote host. You can also use the AWI
(see 6.5.2) to nd the MAC addresses
If your network uses DHCP, the host and zero client obtain
their IP addresses from the DHCP server. If no DHCP server is
available, the host and zero client me out aer approximately
two minutes and adopt the following default IP addresses:
• Zero client: 192.168.1.50
• Host card: 192.168.1.100

1.5 Wake on LAN and remote power cycling
By default, the DXP4 supports Wake on LAN (WoL), allowing
users to wake up the host from standby. To power down or
power cycle the host computer from a remote zero client
requires the installaon of a Remote Power Cable (RPC).
There are two opons for seng up WoL depending on whether
your system supports it directly or not:
• WoL supported;
• WoL not supported - RPC cable required.
1.5.1 WoL supported
Most computers support WoL, though it may not be enabled by
default. When WoL is enabled on the host computer, end-users
can wake up the host computer automacally when they
connect to it from a remote zero client.
WoL requires appropriate BIOS, network card and operang
system support. Refer to your host computer documentaon for
details about enabling this feature.
Example: To enable WoL for Windows 8 computers, you must
edit the Magic Packet and power management properes of
the appropriate network adapter.
1.5.2 WoL not supported - RPC cable required
For an alternave setup, you can install a Remote Power Control
(RPC) cable assembly to interpose the DXP4 between the host
computer’s power switch and the associated motherboard
header (see 3.3.2 Connect Remote Power Cable (Oponal)).
Specically, connect the RPC cable to the RPC socket on the
DXP4 (see 2.6 Internal card connecons).
This allows users to power cycle the host computer from a
remote zero client. Unlike the WoL setup, the RPC setup also
allows users to power cycle, power up and fully power down the
remote PC (for example, if it has blue-screened).
Aer connecng the RPC cable assembly:
• users of Amulet Hotkey DXR zero clients can press the RPC
switch to power cycle the host computer;
• users of Amulet Hotkey DXZ zero clients can use the On
Screen Display (OSD) to power cycle the host computer.
