Hardware Connection
This section describes how to set the connectors of the Mediatrix 4104.
See “Appendix C - Cabling Considerations” on page 379 for more details on the cables the Mediatrix 4104
uses.
Reserving an IP Address
Before connecting the Mediatrix 4104 to the network, Media5 strongly recommends that you reserve an IP
address in your DHCP server – if you are using one – for the unit you are about to connect. This way, you
know the IP address associated with a particular unit.
DHCP servers generally allocate a range of IP addresses for use on a network and reserve IP addresses for
specific devices using a unique identifier for each device. The Mediatrix 4104 unique identifier is its media
access control (MAC) address. You can locate the MAC address as follows:

It is printed on the label located on the bottom side of the unit.

It is located in the sysMgmtMIB under the sysMacAddress variable.

You can dial the following digits on a telephone connected to the Mediatrix 4104:
*#*1
The Mediatrix 4104 answers back with its MAC address. See “Special Vocal Features” on page 13
for more details.
Before Proceeding
Most computers are configured by default to automatically obtain an IP address via DHCP. If the computer
connected to the Mediatrix 4104 is set with a static IP address, you must change the setting. Please refer to
your operating system’s documentation to perform this task.
10/100 BaseT Ethernet RJ-45 Cable
When connecting an Ethernet cable to the Mediatrix 4104, use a standard telecommunication cord with a
minimum of 26 AWG wire size.
You can either use a crossover or straight Ethernet cable to connect in the ETH1 or ETH2 connectors. These
connectors perform automatic MDI / MDIX detection, meaning that they adapt to the type of cable connected
to them.
The auto MDI / MDIX feature works only when the connectors are configured in auto detect mode (see
“Ethernet Connection Speed” on page 161 for more details).
Whenever you force the Mediatrix 4104 to use a specific Ethernet mode (for example 100Mb Full Duplex), the
type of cable to use depends on the other peer. For example, a straight cable is required to connect the
Mediatrix 4104 to a hub or a switch, while a crossover cable is required to connect the Mediatrix 4104 to a PC.
See
“Appendix C - Cabling Considerations” on page 379 for more details.
Warning:
Do not connect the Mediatrix 4104 directly to Telecommunication Systems.
