Note: VBOB has two BNC connectors for each external HD and SD genlock source. You can use either of these connectors as an input or a loop-through.


Rear Chassis LEDs

There are eight LEDs on the rear of the VBOB chassis, as shown in Figure 3-2.

The SD, HD, Genlock, and LVDS LEDs indicate the following:

  • SOLID - Signal present and valid

  • FLASHING - Signal present but unrecognizable (invalid, such as wrong video format)

  • OFF - No signal present

The last LED on the right indicates the processor activity. This LED should flash at a rate of about 1 Hz.

Getting Started

Follow these steps to connect the cables and boot the host system. See Figure 3-1 and Table 3-1 for the location and functional descriptions of the rear panel connectors.

  1. Be sure the VBOB power switch at the back of the chassis is in the Off (o) position.

  2. Connect one end of the power cord to the VBOB power plug and the other end of the cord to your AC power source.

  3. Connect all other cables as applicable.

  4. Turn the VBOB power switch to the On (-) position.

  5. Boot the SGI host system.


    Note: You can find cabling instructions for a specific configuration in the owner's guide provided with your VBOB-related product.
