PWR A and PWR B Status Indicators
If the switch has dual power sources (for redundancy), the switch draws power
from the power source with the higher voltage. If one of the DC power
sources fails, the alternate DC power source powers the switch.
Setup Off Switch is configured as a managed switch.
Solid green Switch is in initial setup.
Flashing gree n Switch is in one of the following states;
• initial setup
• recovery
• initial setup incomplete
Solid red Switch failed to start initial setup or recovery because there is no
available switch port to which to connect the management station.
Disconnect a device from a switch port, and press the Express Setup
button.
PWR A and PWR B
(see PWR A and PWR B
Status Indicators, below)
Off Power is not present on the circuit, or power is not applied to the
system.
Solid green Power is present on the associated circuit.
Port Off No link.
Solid green Link present.
Flashing green Activity. Port is sending or receiving data.
Flashing amber A link blocked by spanning tree violation is sending or receiving data.
Alternating green/amber Link fault. Error frames can affect connectivity, and errors such as
excessive collisions, CRC errors, and alignment and jabber errors are
monitored for a link-fault indication (RJ45 connection only).
Solid amber Port is not forwarding. Port was disabled by management, an address
violation, or spanning tree violation.
After a port is reconfigured, the port status indicator can remain amber
for up to 30 seconds while spanning tree checks the network for
possible loops.
Indicator State Description
If The Status Indicator Color Is
Power is present on the PWR A or PWR B
input Green
Power is not present on the PWR or PWR B
input Red when power is not present, if switch is
configured for dual input power.
Off if the switch is not configured for
dual-input power.
