Powering on the Mediatrix 3300
This chapter describes the initial provisioning of the Mediatrix 3300.
IP Address Discovery or Configuration
This section describes how to contact the Mediatrix 3300's management interface to start with unit
configuration.
Note that the Mediatrix 3300 IPv6 interface is disabled by default.
Once the physical connection is complete and the Mediatrix 3300 is powered up, you must first find out the IP
address the Mediatrix 3300 is using. The Mediatrix 3300's WAN IP address can be set either dynamically or
statically. The default behaviour of the Mediatrix 3300 is to try to obtain a dynamic IP address through a DHCP
server.
You can also access the Mediatrix 3300 through its private LAN interface.
Dynamic WAN IPv4 Address Discovery
The default configuration is 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.
This way, you know the WAN IP address associated with a particular unit.
See the Software Configuration Guide for more details on how to set an external DHCP server.
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 3300 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 stored in the System Information page of the web interface.
If you have not reserved a WAN IP address, you can discover which WAN IP address has been assigned to
the Mediatrix 3300 by either:

consulting your DHCP server's logs to find out details on the DHCP lease that was given to the
Mediatrix 3300.

using a network packet sniffer (e.g., Wireshark) to examine the DHCP messages exchanged
between the Mediatrix 3300 and your DHCP server while the Mediatrix 3300 boots up.
Caution:
If you set a Mediatrix 3300 with a static eth1-4 IPv4 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 3300 is 192.168.0.10.
Caution:
If you are experiencing problems, or if you do not want to use a DHCP server and use a static IP
address instead, perform a Partial Reset procedure, as explained in “Partial Reset” on page 23 .
