Status Indicators

Front Indicators

Switch Indicators
Front panel LEDs are located on the right side of the chassis and display system, fan, and power supply status. The front panel LEDs are labeled either as in Figure A-1 or as in Figure A-2. Check your device for the specific method utilized.

will remain green if a single fan or power supply is missing or in a failed state.
Blue / Blinking Blue| The locater function is active.
Amber / Yellow / Orange| Two or more fans (any combination of fan modules or PSU fans) are disconnected or malfunctioning or incompatible. The switch will automatically execute a “graceful shutdown” shortly.
Fan Status LED| Green| All fan and power modules are operating normally.
Amber / Yellow / Orange| Single fan module is removed or malfunctioning. It is also amber when a PSU is completely removed or has a stuck fan rotor.
Red| Two or more fans (any combination of fan modules or PSU fans) are disconnected or malfunctioning. The switch will automatically execute a “graceful shutdown” shortly.
PSU [1:2] Status LED| Green| PSU is functioning and fully operational. AC is present, Aux output is ON, and Main output is ON.
Red| PSU has been removed or is not operating properly due to AC cord being unplugged, its fan rotor being stuck, or an internal fault.

System could take up to ten minutes to boot up and be ready for operation. Other LEDs could be off.

Port Indicators
Port LEDs, located in the vicinity of their corresponding ports, provide link and operational status.
Figure A-3 displays the Port LED location on the DCS-7050QX-32S switch.

properly.
Green| The fan is operating normally. This LED state is exclusive to its fan module, and independent of the states of its neighboring fans and power supplies.
Red| The fan has failed.

The AC Power Supply Status LEDs are on the power supply modules, as displayed for a representative PSU, in Figure A-5.
