2.9.3 On Screen Display (OSD)
The OSD is available when the zero client is powered on and a
PCoIP session is
not
in progress. Press the multifunction Power
button on the zero client front panel to display the OSD Connect
screen.
From the Connect screen, you can create a new PCoIP session
between the zero client and a remote PCoIP host card or a virtual
desktop. The Options menu in the Connect screen gives access
to various configuration pages (these pages provide a subset of
the functionality provided by the AWI). You must enter a
password to change any zero client settings; see
OSD Connect screen
2.9.4 Restricting access to the management tools
Note:
The security measures described below recommend
disabling the Administrative Web Interface (AWI).
However, do not disable the AWI on your DXZC-AMC zero
clients until after you have made the security-based
configuration changes in
For additional security, we recommend that you disable the
Administrative Web Interface (AWI) and PCoIP Management
Console on your zero clients
before you deploy the zero clients
to end-users
.
With these interfaces disabled, you can only configure a zero
client through its local On Screen Display (OSD). This security
measure prevents malicious third parties from configuring your
zero clients remotely.
To disable the AWI and Management Console and restrict
configuration changes to the zero client’s OSD:
1 From the OSD Options menu, choose Configuration > Access.
2 Select both of the following check boxes:
●
Disable Administrative Web Interface
●
Disable Management Console Interface
If you keep the AWI and CMI enabled, so that zero client
administration is
not
restricted to the local On Screen Display,
you must ensure that any configuration changes are performed
from the
trusted
network on which the zero client is deployed.
If you are concerned about protecting administrative traffic over
an untrusted network and want to ensure that the connection is
confidential, you must use a Virtual Private Network assured to
the classification of the data being exchanged.
2.10 Cooling considerations
Amulet Hotkey zero clients are designed to operate efficiently,
over a long period in a variety of applications. However, for
reliable operation they must be correctly installed and properly
ventilated. In particular, you must always allow sufficient space
around the zero client enclosure for cool air to enter the device
and for hot air to escape. Do not block the air vents. Do not
install in a fully sealed enclosure.
Note:
Amulet Hotkey zero clients are passively cooled. It is
a feature of these products that they run hot. Certain
components inside the zero client use the metal case as a
heat sink, so the unit often feels warm or possibly hot to
the touch. This is normal.
■
Recommended enclosure size:
To ensure adequate cooling
in dual and quad head video applications, the enclosure
must allow the following minimum gaps around the unit:
X=25mm, Y=25mm, Z=25mm.
Note:
These recommendations assume room
temperature is 25°C and the enclosure is fully open
front and back for cable and switch access.
■
Use a spacer to stack units:
If you need to stack zero clients
on top of each other, we recommend that you separate the
stacked units with spacers where S=25mm.
