T Twisted Pair
Port 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 10/100/1000Base-T twisted pair ports.
SFP LEDs Both SFP transceiver slots on the AT-GS950/8POE switch have one L/A
(link/activity) LED which applies to ports 7 and 8. See Table 5 for a
description.
