10/100/1000Base- T Twisted Pair Port LEDs
SFP LEDs
A twisted pair port has two LEDs labeled SPD (speed) and L/A (link/ activity). The SPD LED indicates the port speed. The L/A LED indicates the activity on a port. Both of these LEDs apply to ports 1 through 6 and 7R through 8R.
Table 4 describes the LEDs for the
