Status Indicators
Front Indicators
A.1.1 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.

Table A-1 Switch Indicators LED States (Front)
| LED Name | LED State | Device Status |
|---|---|---|
| System Status LED | Blinking Green | The system is powering up. |
| Green | Normal operations. Due to power supply and fan redundancy, this LED |
will remain green if a single fan or power supply is missing or in a failed
state.
Blue| The locater function is active.
Amber| 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.
Fan Status LED| Green| All fan and power modules are operating normally.
Amber| A 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.
Off| PSU has been removed or is not operating properly due to AC cord being
unplugged, its fan rotor being stuck, or an internal fault.
A.1.2 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.

Table A-2 provides status conditions that correspond to port LED states. Port
LED behavior for QSFP+ and SFP+ ports is consistent.
Table A-2 Port LED States (Front)
| LED State | Status |
|---|---|
| Off | Port link is down. |
| Green | Port link is up. |
| Yellow | Port is software disabled. |
| Flashing Yellow | Port failed diagnostics. |
Rear Status Indicators
Fan and power supply modules are accessed from the rear panel. Each fan and
power supply module contains an LED that reports the module status.
Fan Status LEDs are on the fan modules, as displayed in Figure A-4.

Table A-3 provides status conditions that correspond to fan status LED states.
Table A-3 Fan Status LED States (Rear)
| LED State | Status |
|---|---|
| Off | The fan module is not detected. If it is inserted, it may not be seated |
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
in Figure A-5.
