Power Supply Carrier LEDs
The power supply carrier has two LED indicators (see Figure 4-4). These LED
indicators are driven by the VEM.
Figure 4-4. LEDs On Power Supply Carrier
These power supply status LEDs function as follows:
•
The green LED on the top is the power supply status indicator.
•
The red LED on the bottom is the power supply failure LED. It is normally
off. If a failure has occurred, this LED turns on steadily or flashes at regular
intervals. See Table 4-2 for the meaning of the LED interval patterns.
