Understanding the Status LEDs
The LEDs on the front panel provide you with switch status checking and monitoring. The following section describes the three types of
LEDs.
SYSTEM Status LED
The SYSTEM Status LED indicates if the switch is powered up correctly or if a system alarm has been triggered for troubleshooting.
LINK/ACT/SPD Mode LED
The LINK/ACT/SPD Mode LED indicates the port status LEDs are displaying in link/act/speed mode.
PoE Mode LED
The PoE Mode LED indicates the port status LEDs are displaying in PoE mode.
Port Status LEDs
The Port Status LEDs indicate the current status of each port in either Link/Act/Speed mode or PoE mode. By pressing the
MODE
button
for less than two seconds, you can change LED modes from
LINK/ACT/SPD
mode to
PoE
mode, to check the port status in each mode.
When LINK/ACT/SPD Mode LED Is Lit
When the LINK/ACT/SPD Mode LED is lit, the link/act/spd status is indicated by the LED behavior.
