Panel Row Blanks Removal
To install the new panel row, you must first remove the blank module plates
from the crosspoint buses, as well as from the module slots.
The blank module plate covering the crosspoint buses consists of the Crosspoint
Plate, and Crosspoint Plate Retainer. To remove the blank module plate, you
must first remove the Crosspoint Plate from the top of the control panel, and
then remove the Crosspoint Plate Retainer from inside the control panel.
Use the following procedure to remove the blank module plates:
1.
Power down the control panel. The frame can remain on during this
procedure. Refer to your Vision switcher documentation for
information on shutting down the control panel.
2.
Unplug the Primary and Redundant (if installed) power from the
control panel.
Warning Hazardous Voltage
— Hazardous voltages are
present in the control panel as long as any of the power supplies
are connected to the AC power.
3. Lift up on the control panel lid to gain access to the control panel tub.
4. Remove the 8 screws securing the Crosspoint Plate to the top of the
control panel ( Figure 1 ).
