Figure 20: 8393SF/CPU module LEDs
The switch fabric LEDs and the CPU LEDs serve as a bar graph to indicate card activity. The
SF bar graph increases as the switch fabric usage increases. The CPU bar graph increases
when the CPU actively performs tasks, such as learning MAC addresses, updating routing
tables, or interacting with the device management station.
The following table describes the 8393 SF/CPU module LEDs.
