|
Fault | • When lit, one or more of the ports has failed or the internal temperature has |
(yellow LED) | exceeded acceptable levels. |
| • When flashing, all ports are operational but another error has occurred. Errors |
| appear in an event log. The level of error severity that will cause flashing to start |
| can be controlled using the config sys fault command in the CLI. The default is |
| level 3, Critical. |
| Note: Whether lit or flashing, the switch will continue to operate. Switch |
| functionality may be impaired depending on the event that triggered the |
| Fault LED. Regardless of the cause, the switch requires immediate |
| attention. |
|
|
Power | When lit, the switch is plugged in and the internal power supply is functional. |

Operational | inserted SFPs and that the switch is operational. |
(green LED) | • When flashing, the switch has been configured for multiple zones, and one or |
