Installation:
The CAB 4n product is designed to mount in a standard EIA electronic equipment rack. Because
the CAB 4n includes forced air cooling, adding rack mounted vent panels is not required for most
installations. However, it is recommended that common sense be applied to large installations
where multiple units are mounted in a single rack. It is generally accepted that a ratio of 2:1 is a
good rule of thumb that usually provides adequate performance. In installations where adverse
conditions exist, and room temperatures are likely to rise, additional vents should be installed.
Do not block the fan or any vents when installing the CAB 4n. Proper cooling is essential to
maintain proper operation and long-term stability in this product.
When dressing off wiring harnesses, take care with CAT 5 cables. Do not tie-wrap bundles of
CAT 5 wire too tight. Leave plenty of room for bends, allowing the cable to progress naturally
from the RJ-45 connector. Creating tightly wrapped CAT 5 wire bundles can cause loose crimp
joints and defective terminations.
To successfully install your new CAB 4n product, and perform the testing examples contained in
this manual, you will need the following components:
• A MediaMatrix MiniFrame 208nt-cn or MM™-760nt, MM™-960nt or MM™-980nt
Mainframe or Nion N3 or Nion N6.
• The latest NWare software. (Updates can be downloaded from the MediaMatrix Website)
• PC Monitor, mouse and keyboard.
• At least 1 MM™ DSP-cn CobraNet™ DPU card for MediaMatrix.
• At least 1 CAB 4n with associated MM™ I/O 4 Ch Cards loaded.
• At least 1 generic fast Ethernet 100 Base T network switch*.
• An assortment of CAT 5 cables.
• An audio source, power amplifier and loudspeaker.
In MediaMatrix, the minimum CobraNet network consists of a single MediaMatrix frame or Nion
housing at least one MM DSP-cn CobraNet DPU card, CAB 4n audio bridge with loaded MM™
I/O 4 Ch Cards and a single Ethernet switch. Of course, most systems will include many more
DSP-cn cards and CAB devices, but this is the most basic configuration.
* 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.
