Status Indicators

This chapter includes the following sections:

Front Indicators

System and port status LED indicators are located on the front of the switches.

This section includes the following topics:

Switch Indicators

Front panel LEDs are located on the right side of the chassis and display system, fan, and power supply status. Front Panel displays the front panels of all switches covered by this guide.

Figure 1 displays the CCS-720XP-96ZC2 front panel LEDs.

Table 1. Switch Indicators LED States
LED Name LED State Device Status
System Status Blinking Green System powering up.
Green All power supplies and fans are operating normally.
Blue The locator function is active.
Red A power supply or fan is missing or in a failed state.
Fan Status Green All fans are operating normally.
Red One or more fans are not inserted or have failed.
Power Supply Status Off Power supply is not inserted or is not powered.
Green Power supply operating normally.
Red Power supply has failed.

Port Indicators

Port LEDs, located in the vicinity of their corresponding ports, provide link and operational status. Figure 2 displays the Port LED location on the CCS-720XP-96ZC2 switch. Front Panel displays the port LED locations of all switches covered by this guide.

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. Rear Panel displays the rear panel of all switches covered by this guide.

Fan Status LEDs are on the fan modules, as displayed in Figure 3.

Note: Bezel color indicates airflow direction.

 

The module installation indicator is green when the fan module is properly installed or red when the module is not fully installed. Table 3 provides status conditions that correspond to fan status LED states.

Table 3. Fan Status LED States
LED State Status
Off The fan module is inserted but not receiving power – it may not be properly seated.
Green The fan is operating normally.
Red The fan has failed.

The Power Supply Status LEDs are on the power supply modules, as displayed in Figure 4.

Table 4 provides status conditions that correspond to power supply status LED states.

Table 4. AC Power Supply Status LED States
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 down 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, under the topic Viewing Environment Status, for further information on the show environment commands.
