CB 3000 Crosspoint Buffer and Interface
The window on the front of the chassis allows the fault indicators on the
front of the CB-3000 card to be viewed. (See Figure 216)
Figure 216. CB 3000 Front Panel Status Window
RED LEDs
Beginning at the left side of the window, the first eight RED LEDs are DS1
through DS8, the Output Fault Memory LEDs. These LEDs are normally
off. If any of the LEDs are on, a fault has occurred at some time on the indi-
cated crosspoint bus output.
The next group of three RED LEDs is the INPUT_FAILURE,
OUTPUT_F
AILURE, and FAN_FAILURE LEDs, respectively. These LEDs
are normally off. An on condition indicates the fault described by the LED
name.
Three local changeover switches on the fr
ont of the CB 3000 card are not
accessible from the front panel. They are the local equivalent to the front
panel pushbuttons.
GREEN LEDs
The eight GREEN LEDs at the right side of the display window are Output
Configuration LEDs DS12 through DS19. They indicate the A output
drivers are active on their respective outputs, 0 through 7. These LEDs are
normally ON, indicating the default “A” position. Any LED that is OFF
indicates that its respective output has switched to the “B” driver position.
