Status Indicators
The following topics are covered in this section:
Supervisor Module
While the front panel of each switch can house two supervisors, switch operations require only one. Supervisors display switch status and contain Ethernet management and console ports. The supervisor provides:
- One serial console port
- Two Ethernet management ports (one RJ-45, one optical)
- Two USB ports
- One clock input port
- Several system level status indicator LEDs (System Level Status Indicator LEDs: DCS-7800-SUP-D).
System Level Status Indicator LEDs: DCS-7800-SUP-D
The system status indicator LEDs are shown in Figure 1.

Supervisor Status LEDs
Supervisor Status LED States interprets the states of the supervisor status LEDs for both the active and the redundant supervisor module.

| Supervisor active, Ethernet port not linked | Green | Green | (3) | (3) | (3) | (3) | Off | Off |
1 Assumes redundant supervisor is present.
2 Depends on port operation.
3 Green for normal operation, red if no corresponding component is powered or present.
Note: Arista modular switches take 15 to 30 minutes to boot completely.
Line Card Module Indicators
Each line card module provides one status LED plus LEDs for each port on the card. Line Card Status LED shows a representative line card. The figures in Line Cards indicate the location of the LEDs on each line card.
| 1 | Line card status LED |
| 2 | Port status LED |
Line Card Status LED States interprets the states of the status LED.
| LED State | Status |
|---|---|
| Off | Line card not inserted. |
| Green | Line card operating normally. |
| Yellow (amber/orange) | Line card administratively shut down or booting up. |
| Red | Linecard has failed. |
| Red (blinking) | Locator function is enabled. |
The line card provides LEDs for each port module socket:
- Each LED corresponds to a module.
- A set of four LEDs correspond to each module. When the module is programmed as a 40G port, the first LED in the set reports status. When the module is programmed as four 10G or 100G ports, each port is assigned to an LED within the set.
- For line cards that support OSFP and QSFP-DD ports with one LED per port, Line Card Port LED States interprets the port LED states.
Table 3. Line Card Port LED States LED State Status Off Port link is down for all enabled interfaces. Green Port link is up for any enabled interface. Yellow (amber/orange) Port is disabled in software. Flashing yellow (amber/orange) Locator function is enabled on an interface.
Fabric Module Status Indicators
Fabric Status LEDs are on fan-fabric modules. Rear Panel displays the position of these modules on the rear of each switch. The following figure displays fan status and fabric status LEDs on the DCS-7804 switch. Figure 5 displays fan status and fabric status LEDs on the DCS-7808 and DCS-7816 switches.
Note: The fabric modules are installed vertically in the chassis. They are shown horizontally in the following illustrations.
| 1 | Fabric module top | 3 | Fan module 2 status LED | 5 | Fan module 4 status LED |
| 2 | Fan module 1 status LED | 4 | Fan module 3 status LED | 6 | Fan module 5 status LED |
The following figure displays fan status and fabric status LEDs on the DCS-7812 switch.
| 1 | Fabric module top | 6 | Fan module 4 status LED | 11 | Fan module 8 status LED |
| 2 | Fabric module status LED | 7 | Fan module 5 status LED | 12 | Fan module 9 status LED |
| 3 | Fan module 1 status LED | 8 | Fan module 6 status LED | 13 | Fan module 10 status LED |
| 4 | Fan module 2 status LED | 9 | Fabric module ejector lever | 14 | Fan module 11 status LED |
| 5 | Fan module 3 status LED | 10 | Fan module 7 status LED |
| 1 | Fabric module top | 5 | Fan module 3 status LED | 9 | Fan module 7 status LED |
| 2 | Fabric module status LED | 6 | Fan module 4 status LED | 10 | Fan module 8 status LED |
| 3 | Fan module 1 status LED | 7 | Fan module 5 status LED | ||
| 4 | Fan module 2 status LED | 8 | Fan module 6 status LED |
For the 7816 switch, the lower fabric module fan modules are numbered 9 through 16.
Note:
- DCS-7816R3-FM and DCS-7808R3-FM look similar. Check the label before populating the chassis
- For the DCS-7816 switch, the top and bottom fabric modules form one logical fabric module. Both physical modules in a logical pair power down if either loses power.
- The show module command lists the serial number (SN) of only the bottom-slot Fabric Module.
Fan Status and Fabric Status LEDs on Rear Panel interprets the states of the fan and fabric status LED.
| LED State | Status |
|---|---|
| Off | Module inserted, but status is unknown. |
| Green | Module operating normally. |
| Red | Module failed. |
