Even if the PoE mode is not selected, the LED shows PoE problems when they are detected (Table 1-8).
The PoE LED is only on the switches that support PoE.
PD LED
Applies only to the Catalyst 2960CPD-8PT-L and 3560PD-8PT-S switches. (Table 1-9).

module. The ports can autonegotiate, or you can manually configure each dual-purpose port as either
10/100/1000 with copper connectors or as an SFP-module port, but not as both types at the same time.
See Table 1-7 for LED descriptions.
