Introduction
The CAB 8n is a 1RU device that can be mounted in a number of configurations:
In a 19" EIA equipment rack tray with one unit in the tray.
In a 19" EIA equipment rack tray with two units in the tray.
On a surface
Under a surface. The CAB 8n has four holes that pass right through the case (indicated by
the circles below), which are designed to allow it to be fixed under a surface by #8 or M4
screws.
This product should be installed so that its mounting position does not interfere with
proper ventilation. Do not block air intake or exhaust vents.

Chapter 4 - Installing the CAB 8n
16 Version 1.7.1.0 July 23, 2014
.
What you will need
A MediaMatrix NION with CobraNet interface.
The latest NWare software. (Updates can be downloaded from the MediaMatrix website
(http://mm.peavey.com/downloads/index.cfm).)
A computer running Microsoft Windows, with monitor, mouse and keyboard.
An assortment of CAT 5e or CAT 6 cables.
At least 1 CAB 8n.
An audio source, cables, power amplifier and loudspeaker.
A small Phillips screwdriver.
A small flat-blade screwdriver.
A network switch connected to the CobraNet network.
Note: The selection of a proper network switch is critical for a successful implementation.
Although CobraNet is an Ethernet protocol, there are performance issues that must be
considered when selecting this switch for use in CobraNet audio systems.
In MediaMatrix,the minimumCAB 8n CobraNet system consists of a single NION, a CAB 8n
and a single Ethernet switch. Many systems will include more NIONs and CAB devices, but
this is the most basic configuration.
Connections
CobraNet network connection
The first priority is the CobraNet™ network connection. The RJ-45 connectors on the
CobraNet interface are designed to connect with standard, off-the-shelf Category 5, 5e or 6
cable for use with standard Ethernet network switches.
Notes:
The network must be properly designed for each system. If you lack experience in
networking, we suggest that you partner with someone with networking experience.
Gigabit switches are recommended.
CAT 5e or CAT6 cables are recommended.
A typical CobraNet system includes a connection from each CAB to a network switch. An
additional network cable connects the switch to one or more NION CM-1 cards.
Note: The example below is the most basic configuration. Large systems on managed
networks can get very complex. We recommend that you get this configuration working
before attempting a more complex one.
