found on front panels of the AT-8000GS/24 Gigabit Ethernet Switch
and AT-8000GS/48 Gigabit Ethernet Switch.
Port LEDs — These LEDs indicate each port’s status. There are
different types of port LEDs which are described in the following
sections:
– “RJ-45 Port LEDs on AT-8000GS/24 & AT-8000GS/
48” on page 19.
– “RJ-45 Port LEDs AT-8000GS/24POE” on page 21
– “SFP Port LEDs” on page 22
– “Stacking Port LEDs” on page 23
