Figure 19 on page 20 shows the LEDs that indicate the status of one of the four port
parameters—speed, duplex mode, administrative status, and Power over Ethernet (PoE)
status. Use the Factory Reset/Mode button on the far right side of the front panel to
toggle the Status LED to show the different port parameters for RJ-45 network ports.
You can tell which port parameter is indicated by the Status LED by looking at which port
status mode LED ( SPD , DX
switch models with RJ-45 network ports that do not provide PoE.
