EX4100 and EX4100-F switches have network port mode LEDs (labeled SPD, DX, EN, and POE) on the
right side of the front panel (see Figure 41 on page 51). These LEDs indicate the status of the network
ports. Use the mode buon on the right side of the front panel to toggle the status LEDs. You toggle the
status LEDs to show the dierent port parameters for the network ports. The LED that is lit indicates
the port parameter. Table 10 on page 51 describes the status LEDs.
