Status Indicators

This section discusses the following topics:

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:

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 modules.

1 Assumes a 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.

 

Linecard Module Indicators

Each linecard module provides one status LED plus LEDs for each port on the card. Linecard Status LED shows a representative linecard. The figures in linecards indicate the location of the LEDs on each linecard.

 

Figure 2. Linecard Status LED

 
1 Linecard status LED
2 Port status LED

 

Linecard Status LED States interprets the states of the status LED.

 

Table 2. Linecard Status LED States
LED State Status
Off Linecard not inserted.
Green Linecard operating normally.
Yellow (amber/orange) Linecard administratively shut down or booting up.
Red Linecard has failed.
Red (blinking) Locator function is enabled.

 

The linecard provides LEDs for each port module socket:
  • Each LED corresponds to a module.
  • A set of four LEDs correspond to each module. The first LED in the set reports status when the module is programmed as a 40G port. When the module is programmed as four 10G or 100G ports, each port is assigned to an LED within the set.
  • For linecards that support OSFP and QSFP-DD ports with one LED per port, Linecard Port LED States interpret the port LED states.

     

    Table 3. Linecard 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 the software.
    Flashing yellow (amber/orange) Locator function is enabled on an interface.

     

Fabric Module Status Indicators

Fabric Status LEDs are on fan-fabric modules. The Rear Panel displays the position of these modules on the rear of each switch. The following figure displays the fan status and fabric status LEDs on the DCS-7804 switch. Figure 5 display 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 the LEDs for the fan status and fabric status on the DCS-7812 switch.

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    

 

 

Figure 5. DCS-7808R3-FM and DCS-7816R3-FM Fabric Module and Fan Status LEDs
 
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 turn off 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 the Rear Panel interpret the state of the fan and fabric status LED.
