System LEDs
The following table describes the system LED designations.
Table 2-2. System LEDs
LED Designation
Power/Status LED • Solid Green = Power is supplied to the switch and the switch is operating
normally.
• Solid Yellow = The switch is booting.
• Off = Power is disconnected.
PoE MAX LED • Off = There is at least 7W of PoE power available for another device.
• Solid Yellow = Less than 7W of PoE power is available.
• Flashing Yellow = The PoE MAX LED was active in the previous two minutes.
Device Hardware Interfaces
RJ-45 Ports
RJ-45 ports are autosensing ports. When inserting a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10, 100, or 1000 Mbps) and duplex mode (half-
duplex or full-duplex) of the attached device. All ports support only unshielded twisted-pair (UTP)
cable terminated with an 8-pin RJ-45 plug.
PoE Status
(Right LED on each RJ-45 port)
• Off = No PoE powered device (PD) connected.
• Solid Green = The PoE PD is connected and the port is supplying
power successfully.
• Flashing Yellow = One of the following failures resulted in stopping
power to that port:
– Short circuit on PoE power circuit.
– PoE power demand exceeds power available.
– PoE current exceeds PD's classification.
– Out of proper voltage band (44 ~ 57 VDC).
SFP Port Indicate LED • Off = No link is established on the port.
• Solid Green = A valid link is established on the port.
• Flashing Green = Packet transmission or reception is occurring on
the port.
