2.3 Installation
V2040 matrix switching bays are manufactured for standard
19-inch rack mounting and have a rack height of 10.5 inches. Bays
must be installed with a minimum of 1.75-inch clearance between
each bay (one rack unit). Installation personnel must ensure proper
airflow around the bays to provide adequate ventilation. In multiple
bay configurations, identify the various bays carefully before
mounting. In all multiple bay systems, place the video inputs near
the top of the racks.

Figure 2-14. Bay Mounting Dimensions
Observe the following guidelines when mounting V2040 bay into a
rack:
Installation preparation:
1.
Plan the layout of the equipment in the racks before installing
equipment
2.
Take an inventory of all rack equipment hardware, brackets,
blank panels, etc. Reorder any missing parts immediately. This
avoids delays in the installation process.
3.
Provide a minimum of 1.75 inches (4.4 cm) of empty space
between each piece of equipment for ventilation.
4.
Use at least one blower or fan per rack and place it in the bottom
of the rack. Thus, air is drawn in at the bottom of the rack and
vented at the top.
Installation procedure:
1.
Power off to ensure that the device will not power on during the
installation.
2.
Take off the eight 0.25’’ pan head screws used to secure the
V2040 matrix bay.
3.
Take off the rubber washer on V2040 bottom.
4.
Put the V2040 matrix bay on the bracket and make the ears cling
to the rack.
Fasten the bay ears onto the rack with the eight 0.25’’ pan head
screws.
Carefully make a detailed plan before installation. The operation of
each piece of equipment should be confirmed as early as possible
during the installation procedure. It is easier to remove a few
temporary connections after a confirmation check than it is to
disconnect and re-wire a large number of “permanent” connections.
2.4 Hardware Connection
Each V2040 Matrix Switching Bay can accommodate one Power
Supply Module, one Central Processing Unit (CPU) Module, and a
maximum of 16 modules such as Video Input Modules and Video
Output Modules. All system connections are made on the rear
panels of V2040 modules. Refer to
Typical V2040 Application
Diagram
in
System Features
for illustrations of typical system
connections.
Note:
All internal switch settings on the modules should be made
before system connections are started (see
Module Setup
in this
chapter). Ensure that all connections are properly completed before
applying power.
To facilitate maintenance and assist in service, all connecting cables
should be identified with source/destination numbers.
Note:
All the connection diagrams in this section adopt a V2040
Matrix Switching Bay configured with one Power Supply Module,
one Data Buffer module, 4 VOMs (four in the left) and 12 VIMs.
2.4.1 Video Input Connections
A single Video Input Module provides up to 16 video inputs. To
connect an external video source (e.g., a camera) to its associated
video input terminal:
1.
Properly install the camera according to relevant manuals.
2.
Identify the camera with a desired camera number, and then
identify the BNC terminal on a VIM module rear panel that
designates the same camera number. (See
Module Setup - Video
Input Module Switches
in this chapter.)
3.
Connect the camera to the associated BNC terminal connector
with a video cable. Please refer to the following table to select
appropriate video cables.
