Section 2 — Startup & Configuration
Powering Up
The Model 3000 is designed for continuous operation. It may
already be on and operating; however, the following power-up
procedure is provided in the event that it isn’t:
1. Turn on the power switch on the front of the Signal Processor
Power Supply. Verify that the power supply voltage LEDs on
the front of the Power Supply are lit and that the fans in the
Processor are on. If the Processor is equipped with a
redundant power supply, turn on that supply also.
2. Raise the Control Panel and turn on the power supply switch.
If a redundant power supply is included in the Control Panel,
turn on both power supply switches. Verify that the green
RUN LED on the control panel CPU Board is lit. This board is
located in the middle of the control panel tub on the Model
3000-2, and in the upper control panel in the Model 3000-3.
3. Verify that the Menu Display on the upper Control Panel is on
and displaying the “Grass Valley” sign-on logo.
4. Verify that the pushbutton lamps on the panel are on and that
the E-MEM and Transition subpanel readout LEDs are on.
If one of these indications is incorrect, turn off all power supplies
and refer to the Diagnostics and Troubleshooting section of the
Installation and Service manual.
Boot-Up
When the system is turned on, data stored in the User-Defined
Default memory is loaded into the Current Working Buffer
memory, which sets the initial state of the switcher.
