Status Indicators
This section discusses the following topics:
Front Indicators
Front panel LEDs are located on the right side of the chassis and display system, fan, and power supply status.
Switch Indicators
The front panel LEDs are labeled as shown in the Figure 1 - System Status Indicators or the Figure 2 - System Status Indicators figures. Check your device for the specific method utilized.
| 1 | System status LED | 3 | Power supply 1 status LED |
| 2 | Fan status LED | 4 | Power supply 2 status LED |
| 1 | System status LED | 3 | Power supply 1 status LED |
| 2 | Fan status LED | 4 | Power supply 2 status LED |
| LED Name | LED State | Device Status |
|---|---|---|
| System Status LED | Blinking Green1 | 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 / Blinking Blue | The locator function is active. | |
| Amber / Yellow / Orange | Two or more fans (any combination of fan modules or PSU fans) are disconnected, malfunctioning, or incompatible. | |
| 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 the AC cord being unplugged, its fan rotor being stuck, or an internal fault. |
1. The system could take up to ten minutes to boot up and be ready for operation. Other LEDs could be off.
Port Indicators
Port LEDs near their corresponding ports provide a link and operational status.
Figure 3 - Port LEDs display the Port LED location on the DCS-7050QX-32S switch.
| 1 | Port 4 LED | 3 | Port 2 LEDs |
| 2 | Port 3 LEDs | 4 | Port 1 LEDs |
Table 2 - Port LED States (Front) provides status conditions corresponding to port LED states. Port LED behavior for QSFP+ and SFP+ ports is consistent.
| LED State | Status |
|---|---|
| Off | Port link is down. |
| Green | Port link is up. |
| Yellow / Orange / Amber | Port is software disabled. |
| Flashing Yellow | Software controlled. |
Rear Status Indicators
You can 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 module status LEDs are on the fan modules, as displayed in Figure 4 - Fan Status LED.
| 1 | Fan module status LED |
Table 3 - Fan Status LED States (Rear) provide conditions corresponding to the fan status LED states.
| 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 for a representative PSU, in Figure 5 - AC Power Supply Status LED.
| 1 | Power supply status LED |
Table 4 - AC Power Supply Status LED States (Rear) provides conditions corresponding to the AC power supply status LED states.
| Power Supply State | PWR-500AC-F
PWR-500AC-R |
PWR-511-AC-RED
PWR-511-AC-Blue |
|---|---|---|
| Input power present Normal operation | Green | Green |
| Input power present Power Supply fault | Yellow / Amber / Orange | Yellow |
| No Input power Supply installed in chassis | Off | Off |
| Input power present Supply not installed in chassis | Green | Green |
The DC Power Supply Status LEDs are on the power supply modules, as displayed for a representative PSU, in Figure 6 - DC Power Supply Status LED .
| 1 | Power supply status LED | 3 | Battery Return |
| 2 | -48V | 4 | Protective Earth |
Table 5 - DC Power Supply Status LED States (Rear) provides conditions corresponding to the DC power supply status LED states.
