2 Avocent Emerge ECMS2000U Extender Installer/User Guide
Computer Access Node
The Computer Access Node connects externally to the video, audio and USB ports of the
remote computer.
The Computer Access Node is attached directly to the remote computer and draws its power
directly from two USB ports on the remote computer. This removes the need for additional power
supply connections at the rack.
NOTE: If the remote computer cannot supply the required power or if two USB connections are not available, an
external power supply (part no. ECMS2000-PSU) can be obtained from Avocent.
The Computer Access Node captures, compresses and encrypts the computer’s media streams and
transmits them to the User Access Node over a standard TCP/IP network.
User Access Node
The User Access Node enables the desktop user’s keyboard, mouse, video, and audio devices to
connect to the Avocent Emerge ECMS2000U Extender. It is available as a desktop
user station.
Automatic connection
When the User Access Node is powered up, a connection is automatically established with the
remote computer via the Computer Access Node. No intervention is required from the user. See
Accessing the System on page 14.
Ethernet addressing
The User Access Node and the Computer Access Node are IP-addressable devices; this gives you
the flexibility to locate back-racked computers anywhere within your enterprise and at any distance
from your desktop users. The User Access Node and the Computer Access Node use standard
network protocols to transfer data streams between the remote computer and the peripheral devices
located at the user’s desk. The Avocent Emerge ECMS2000U Extender can operate on a network
connection of 100 Mbps or 1 Gbps. For optimum performance a 1 Gbps connection is
recommended. For more information see Chapter 2.
Multiplatform support
The Computer Access Node is connected to the remote computer via USB connectors. This enables
the Avocent Emerge ECMS2000U Extender to interoperate seamlessly with PC, Sun and
Macintosh target computers. PC, Sun and Macintosh USB keyboards can be connected to the User
Access Node. PS/2 keyboards and mice can also be used.
You can attach the Avocent Emerge ECMS2000U Extender to computers running the following
operating systems:
• Microsoft WindowsTM
