LED Descriptions
:
There are several types of front panel LEDs:
SYS (System) LED indicates if the switch is powered up
correctly or if there is a system alarm triggered for
troubleshooting. Green On = switch is powered ON
correctly. Green Off = switch is not receiving power.
Red On = An abnormal state, such as exceeding
operating temperature range, was detected in the switch.
Mode LEDs indicate the mode of all RJ45/SFP ports on the switch. You can press the Mode/Reset button alternately to
switch between the two different modes (Link/Activity/Speed mode and PoE mode).
Link/Act/Speed Green LED On = Port Status LEDs display link status, network activity and speed of each port.
RJ45 green = 1000 Mbps; amber = 10/100 Mbps. SFP green = 1000 Mbps; amber = 100 Mbps.
PoE LED Green On = RJ45 Port Status LEDs display PoE powering status of each port.
Power Supply LEDs on the back panel indicate Power Supply status. DC Green On = DC input is ready.
Red On = DC input has failed. Off = DC input is off. AC Green On = AC input is ready. Red On = AC input has failed.
Red Off = AC output is off.
Port Status LEDs: indicate the current status of each RJ45 and SFP port. Press the Mode button for less than 2 seconds
to change the LED mode to Link/Act/Speed Mode or PoE Mode. See the Install Guide for LED behavior.
