Physical Installation
Remote Panels
Remote control panels are designed to fit into standard 19 inch equipment
racks. Panels can be mounted at any angle.
Panels are designed to fit into horizontal desks with a minimum of depth
to allow for knee room. Refer to Section 4: Control Panels for the depth of
the panels.
Equipment Frames
All frames are designed to be mounted in standard 19 inch equipment
racks. Standard panels are 5.15 in (130mm) deep plus connectors.
When preparing for installation keep in mind that the modules are
plugged in from the front and extra space is required for the modules to
mount on an extender module. Allow at least 31.5 in. (800mm) clearance at
the front for maintenance.
The depth of the frame is 19 in. (485mm) plus connectors from the front of
the equipment rack. In addition allowance must be made for the numbers
of cables to be installed at the rear of the frame.
Cooling
Power dissipation in most frames is relatively low and cooling is achieved
by natural convection through the sides of the frame. However the 1RU
Serial Digital Video Router is fan cooled, drawing cool air in from the right-
hand side of the frame and expelling it at the left-hand side of the frame.
It is important that the ventilation slots in the lid of the this unit are not
obstructed;
it is perfectly acceptable to install a control panel or another
shallow unit immediately above the unit but not another frame.
In the interests of long term reliability it is advisable, where possible, to
leave a 1RU gap or to fit a unit with a depth of less than .78 in (200 mm)
above every fourth frame.
The 3RU Video Router and 3RU Serial Digital Video Router are also fan
cooled, drawing cool air in from the rear of the frame and expelling it at the
left-hand side of the frame.
In all cases it is important to keep the apertures clear of obstructions eg
cables.
If a 1RU frame is fitted into a mobile vehicle, it is strongly recommended
that some type of rear support should b e used to prevent bending. The
support bar should be designed to fitthe depth of the equipment racks.
