LEDs on the Module Panel
The 8000-48PC-E module provides LEDs indicating system states. The Status LED
indicates the operating status of a board itself, and each port provides a Link/ACT LED to
indicate the operating status of the port itself. The Link/ACT LED has different meanings
depending on the PoE Mode LED. Table 1-11 shows their detailed meanings.
