Red Indicators: Disconnected Hardware
Red status is defined in circumstances where the hardware does not get connected or becomes inaccessible. It may be network-related, hardware failure, or communication issues. It requires prompt rectification to get back to normal operation.
- Action Required: Physically check the device's physical connections, the power, and the network configuration. If the problem can't be resolved, replace or repair the hardware.
- Visual Representation: Red is a very eye-catching warning, prompting immediate action to resolve the issue and restore normal operation.
