2.4 IP and MAC addresses
Before you set up a zero client, make a note of these details:
■
MAC and IP address of the remote PCoIP host
■
MAC and IP address of the zero client
Find this information on the base of the zero client and on
the configuration record/serial number label of the remote
host. You can also use the Administrative Web Interface (
) to find 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 time out after approximately
two minutes and adopt the following default IP addresses:
Zero client:
192.168.1.50
Host card:
192.168.1.100
2.5 Power supply
Amulet Hotkey DXZC-AM zero clients are supplied with a mains
to DC power supply that self-senses the incoming voltage
(110-240VAC). This power supply has a locking DC connector for
use with the zero client. To release the connector, pull the
locking sleeve away from the rear of the zero client.
Important!
Use only this power supply with the product.
The Amulet Hotkey part number is CA-XX01-0011.
2.6 Network bandwidth
PCoIP uses the Internet Protocol (IP) to transmit data
between the host and client. The data can be routed over any
IP-compatible infrastructure between offices or across
continents. In every case, performance depends on the available
bandwidth and signal latency.
How much bandwidth is required? This depends on several
factors, including the number of pixels changing from frame to
frame, the number and resolution of screens to be encoded, and
settings made by the user. Different displays and usage will
generate different bandwidth requirements.
For example, a dual video head system running a word
processor, spreadsheets, and 2D illustrations/designs will
typically use between 1 and 10 Mbit/s.
Because the exact bandwidth requirements for PCoIP are
difficult to predict, use the following values as a guide only:
■
With no USB or audio data, PCoIP uses approximately
32Kbit/s per pair of monitors.
■
General office use (that is, writing documents) consumes
between 300-500Kbit/s.
■
PCoIP only sends display changes, so an idle display
generates very little traffic.
■
A significant display change (such as minimising or restoring
a window) can cause a brief peak of around 4-5Mbit/s.
■
USB transfers generate up to 6Mbit/s of traffic in the
direction of the transfer.
■
Audio requires around 2Mbit/s.
■
Playing full-screen video can use up to 70Mbit/s.
In all cases, PCoIP builds to a lossless image. If the required
bandwidth is not available, PCoIP dynamically adjusts the quality
to match. You can also use the zero client management tools
(see
) to optimise performance for most conditions.
If bandwidth usage is a concern, we recommend testing and
monitoring on your network. For assistance, please contact
Amulet Hotkey.
2.7 LED status indicators
The DXZC-AM and DXZC-AMC have status LEDs on the front and
rear panels:
■
Front panel LEDs show the status of the PCoIP connection
and the power status. See
and
■
Rear panel LEDs associated with the RJ45 or SFP network
connection indicate current network activity. See
in
section 4.2.
2.8 Support for connection brokers
All Amulet Hotkey zero clients can be configured to use a third
party connection broker (also known as a connection
management server). The following connection broker products
include PCoIP support:
■
VMware View Connection Server
■
Leostream Connection Broker
Connection brokers simplify the administration effort for
managing large complex PCoIP systems. A connection broker
interacts with systems such as Active Directory to dynamically
assign PCoIP hosts to zero clients based on the identity of the
user establishing a connection from the zero client. Connection
brokers are also used to allocate a pool of hosts to a group of
zero clients.
You can use any of the available management tools (see
) to specify the connection broker. You must
provide the IP address or DNS name of the connection broker.
You must also specify the ‘Connection Management Interface’
connection type for the PCoIP session.
