1.4 LED indicators information

There are many LEDs on the front panel of switch, after the power on, these LEDs will reflect the
current status truly within the switch, we explain below:
There is one power LED on the left side of front panel, whenever power is applied, it lights with
green, below it, there is Diagnostic LED, it will go blinking during the power-on diagnostics. There
are two more FAN status LEDs aside the power LEDs, the upper one indicate the left fan status inside
the switch, it vanishes when fan works normally, and will goes RED while fan is stop or with
malfunction, the lower one indicates the same for the fan at right side within the switch.
Each RJ-45 of 10/100M is with two LEDs built-in on its upper corner, left one indicates link status
and activity, while the right one indicates the speed information.
Each RJ-45 of 10/100/1000M for gigabit module (optional) is somewhat different. Upper yellow LED
indicates for 10M LINK, middle green LED indicates for 100M LINK, but for 1000M, or Gigabit,
both upper and middle LEDs are lit when gigabit port is link with other Gigabit port.
