SFP LEDs

AT-GS950/8POE Gigabit Ethernet WebSmart Switch Installation Guide

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 10/100/1000Base-T twisted pair ports.

Table 4. Twisted Pair Port LEDs

LED	Function	State	Description
SPD	Link Status	Off	The port has established a link at
	and Activity		10/100Mbps or no link has been
			established.
