Mediatrix 4100
Starting the Mediatrix 4100 for the First Time
The default MIB parameters are set so that the unit can be directly plugged into a network and provisioned
with a DHCP server. Media5 strongly recommends to set your DHCP server before installing the unit on the
network. See “Chapter 3 -
IP Address and Network Configuration” on page 41 for more details.
If you are experiencing problems, or if you do not want to use a DHCP server, perform a Recovery Mode
procedure, as explained in “Recovery Mode” on page 18.
IP Address Discovery or Configuration
Once the physical connection is complete and the Mediatrix 4100 is powered up, the first thing to do is find out
the IP address the Mediatrix 4100 is using. The Mediatrix 4100's IP address can be set either dynamically or
statically. The default behaviour of the Mediatrix 4100 is to try to obtain a dynamic IP address through a DHCP
server.
Dynamic IP Address Discovery
Before connecting the Mediatrix 4100 to the network, Media5 strongly suggests that you reserve an IP address
in your DHCP server for the unit you are about to connect (“
Reserving an IP Address” on page 9).
If you have not reserved an IP address, you can discover which IP address has been assigned to the Mediatrix 4100 by
either:
 consulting your DHCP server's logs to find out details on the DHCP lease that was given to the
Mediatrix 4100.
 using a network packet sniffer (e.g., Wireshark) to examine the DHCP messages exchanged
between the Mediatrix 4100 and your DHCP server while the Mediatrix 4100 boots up.
 To start the Mediatrix 4100 with a dynamic IP address:
1. If you need to discover the IP address of the Mediatrix 4100, install and start your network packet
sniffer.
2. Power on the Mediatrix 4100 by connecting the other end of the power cord to an electrical outlet.
The electrical outlet must be installed near the Mediatrix 4100 so that it is easily accessible.
Default Static IP Address Configuration
If there is no DHCP server in your network, then the IP address has to be configured statically.
 To start the Mediatrix 4100 with a static IP address:
1. With a 10/100 Hub and two 10/100 BaseT Ethernet RJ-45 straight cables, connect both cables to
the Hub; one of them is connected into the ETH1 connector of the Mediatrix 4100 and the other one
links the computer to the Hub.
Note: This section applies to the IP configuration of the ETH1 port.
Caution: If you set a Mediatrix 4100 with a static eth1-4 IP address in a subnet (for instance,
192.168.200.1) and the eth5 interface receives a dynamic IP address in the same subnet (via a DHCP
server or PPP peer), you will not be able to contact the unit via the WAN. You must be careful that a dynamic
IP address does not overlap a static IP subnet that is already configured. Note that the current default value
of the Mediatrix 4100 is 192.168.0.10.
Note: If the Power LED is always blinking and never turns on, this means that the Mediatrix 4100 cannot
find a DHCP server. Check that you have a DHCP server properly configured on your network. If you do not
have a DHCP server, go to the section “
Default Static IP Address Configuration” on page 12.
