Status Indicators

The Status Indicators section discusses the following topics:

Front Indicators

Switch Indicators

Locate the front panel LEDs on the right side of the chassis, where the LEDs display the system, fan, and power supply status. The front panel LEDs are labeled in Figure 1 for a representative switch.

Figure 1. System Status Indicators

1 25G SFP ports 2 System status LED 3 Fan status LED
4 Power supply 1 status LED 5 Power supply 2 status LED 6 100G QSFP ports
7 5G PoE+ ports 8 2.5G PoE+ ports    

 

Table 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 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 the AC cord being unplugged, its fan rotor being stuck, or an internal fault.

 

Port Indicators

Port LEDs near their corresponding ports provide the link and operational status. Port LEDs display the Port LED location on the DCS-7050QX-32S switch.

2 Port 2 LEDs 4 Port 4 LEDs

 

Port LED States (Front) provides status conditions corresponding to port LED states. Port LED behavior for QSFP+ and SFP+ ports is consistent.

Table 2. Port LED States (Front)
LED State Status
Off The port link is down.
Green The port link is up.
Yellow The port is software disabled.
Flashing Yellow The port failed diagnostics.

 

Rear Status Indicators

Access the fan and power supply modules 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 Fan Status LED.

Fan Status LED States (Rear) provide conditions corresponding to fan status LED states.

Table 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 the Representative AC Power Supply Status LED (PWR-1021-AC-RED) .

AC Power Supply Status LED States (Rear) provides conditions corresponding to the AC power supply status LED states.

Table 4. AC Power Supply Status LED States (Rear)
Power Supply State PWR-1021-AC-RED
Input power present Normal operation

Green

Input power present Power Supply fault ON/OFF: ON when PSU output is ON, OFF when PSU Output is OFF
Input power present Power Supply FAN fault FLASH 800 ms ON / 800 ms OFF
No Input power Supply installed in chassis OFF
Input power present Supply not installed in chassis Green

 

Note: You can narrow the error condition by logging in to the switch to view the specific device state. Refer to the Arista User Manual's Switch Environment Control chapter underViewing Environment Status, for further information on the show environment commands.
