• 100Mbs-HalfDuplex
• 10Mbs-FullDuplex
• 100Mbs-FullDuplex
A half-duplex connection refers to a transmission using two separate channels for transmission and
reception, while a full-duplex connection refers to a transmission using the same channel for both
transmission and reception.
If unknown, select Auto detect so that the Mediatrix 4104 can automatically detect the network
speed.

Speed and Duplex Detection Issues
There are two protocols for detecting the Ethernet link speed:

An older protocol called parallel detection.

A more recent protocol called auto-negotiation (IEEE 802.3u).
The auto-negotiation protocol allows to detect the connection speed and duplex mode. It exchanges
capabilities and establishes the most efficient connection. When both endpoints support the auto-negotiation,
there are no problems. However, when only one endpoint supports auto-negotiation, the parallel detection
protocol is used. This protocol can only detect the connection speed; the duplex mode cannot be detected. In
this case, the connection may not be established.
The Mediatrix 4104 has the possibility to force the desired Ethernet link speed and duplex mode by disabling
the auto-negotiation and selecting the proper setting. When forcing a link speed at one end, be sure that the
other end (a hub, switch, etc.) has the same configuration. To avoid any problems, the link speed and duplex
mode of the other endpoint must be exactly the same.
Network Settings
The Network Settings section allows you to set the IP information the Mediatrix 4104 needs to work properly.
This section is vital to the proper operation of the Mediatrix 4104. If a field of this group is not properly set, the
Mediatrix 4104 may not be able to restart and be contacted after it has restarted.
You can also set this parameter via SNMP, as described in “Chapter 8 - IP Address and Network
Configuration” on page 141 .

To set network parameters:
1. In the Network Settings section of the Network Settings page , select the configuration source of the
network information in the IP Address Source choices.
Caution:
Whenever you force a connection speed / duplex mode, be sure that the other device and all
other intermediary nodes used in the communication between the two devices have the same configuration.
See
“Speed and Duplex Detection Issues” on page 34 for more details.
Table 23: Network Settings Configuration Sources
Source Description
Static You manually enter the value and it remains the same every time the Mediatrix 4104
restarts. Use the static configuration if you are not using a DHCP server or if you want
to bypass it.
DHCP The value is obtained at start-time by querying a DHCP server and using standard
DHCP fields or options. Using the DHCP configuration assumes that you have properly
set your DHCP server with the relevant information. See
“Chapter 8 - IP Address and
Network Configuration” on page 141 for more details.
