to all installations of the software. As a result, the MAC address is the
same on many different computers.
Without a unique MAC address, users sometimes are unable to connect
to a server, or will connect to a server, and subsequently cause another
device with the same Hardware ID to be disconnected from the server. If
the MVC 2050 is disconnected from the server, it automatically attempts
to reconnect, and the resulting conflicts will prevent a stable connection
from being made.
Select the Auto-Create button on the Settings > Hardware ID screen to
prevent conflict with another device. Auto-Create fabricates a random
value, which is unlikely to be repeated by another device.
Table 8 describes items on the Hardware ID screen.

Selection Description
Hardware ID This box contains the MAC address for the Ethernet
hardware installed in your device. MVC 2050 uses the
MAC address of the Ethernet hardware as its
Hardware ID. You can change this value if there is
more than one MAC address, or if the device is using
an Extranet client that hides the true MAC address.
For example, the Nortel Contivity Extranet Switch
uses a single MAC address for all clients. This can
cause connection problems with your communication
server.
Auto-Create This changes the MAC address that appears in the
Hardware ID box. If your device has more than one
MAC address, press the Auto-Create button to cycle
through the set of MAC addresses on your computer.
Auto-Create also makes up random Hardware IDs, in
case the Ethernet hardware addresses are not unique
to the communication server.
