# Boot Sequence

Understanding the boot sequence of your **CloudBox** is important for ensuring that the system is starting up correctly and that all components are functioning as expected. During the boot process, the status of the **LED indicators** and the **cooler** provide valuable feedback about the current state of the device.

Here’s a breakdown of the typical boot sequence and the meaning behind each LED status:

## Initial Boot Sequence (First 10 Seconds)

1. **LED Status**:
   * **Power LED**: Solid blue.
   * **Start LED**: Solid red.
2. **Cooler Status**:
   * The **cooler** is active during the initial boot phase, ensuring the system maintains optimal temperature while components initialize.

This state lasts for approximately **10 seconds** as the CloudBox initializes its systems.

## After 10 Seconds

After the initial 10 seconds, the system transitions into its operational checks:

1. **LED Status**:
   * **Start LED**: Begins to blink **every 1000 ms** (once per second).
2. **Cooler Status**:
   * The **cooler** turns off as the system completes its boot process.

This indicates that the CloudBox is finishing its startup routine and checking for any potential issues.

## System Status After Boot

Once the boot sequence is completed, the **Start LED** will indicate the status of the CloudBox:

1. **Normal Operation (System OK)**:
   * **Start LED**: Solid red.
   * This indicates that the system has successfully booted, and the CloudBox is ready for use.
2. **RFID Reader Not Detected (READERNOTOK)**:
   * **Start LED**: Blinks rapidly **every 250 ms**.
   * This status indicates that the RFID reader is either not connected or not configured correctly. The CloudBox will continue to attempt to detect the reader.
3. **System Updating (UPDATING)**:
   * **Start LED**: Blinks slowly **every 3000 ms** (once every 3 seconds).
   * This status shows that the CloudBox is in the process of updating its firmware or software. Wait for the update to complete before interacting with the system.

## Summary

The **CloudBox boot sequence** provides a clear indication of the system's status through its **LED indicators** and **cooler operation**. In the first 10 seconds, both the **Power** and **Start LEDs** are solid, and the cooler is active. After this, the system checks its components and gives feedback through the **Start LED**. A solid red Start LED indicates that the CloudBox is ready, while different blinking patterns signal issues or updates in progress.

Understanding these indicators ensures that you can quickly diagnose and respond to any potential issues during startup.
