Removing Modules From the Frame
There are two types of modules or circuit boards in the Signal Processor Frame.
The frame modules are slide-in units that can be removed for servicing or
replacement. Smaller submodules called mezzanines mount on the frame
modules. The locations of the Signal Processor Frame bays, circuit modules and
mezzanines are illustrated in figures in Section 2 or Section 3 of this manual.
Two circuit module extenders are provided with the system. One is for use with
the main video processing and control modules located in the front bays of the
switcher. The second is for use with the I/O and communications Modules in the
rear bays. The extender modules allow operation of the system while providing
access to test points and adjustments that would be inaccessible with the module
seated normally.
To remove a circuit module from the front A or B Bay of the Signal Processor
Frame, proceed as follows:
1.
Release the captive screws on the front door of the Signal Processor Frame by
turning them counterclockwise. open the door.
2.
Remove the modules by unlocking the top and bottom levers as shown in
. Pull the circuit module straight out and away from the frame.
3.
Set the module on a static free surface and be aware there are fragile
components on either side of the circuit board.
