Power Diagram
The reComputer Industrial R20xx supports two power supply options: DC terminal and PoE port. This provides flexibility in power supply selection and allows for easy integration with various power sources.
2-Pin Power Terminal
The reComputer Industrial R2000 is supplied with a terminal DC voltage of 9~36V. The power supply is connected via the 2-pin power terminal block connector.
To ground the reComputer Industrial R2000, the ground wire can be secured to the screw located at the right of the power terminal.
PoE
The ETH0(PoE PD) port of reComputer Industrial R2000 can support PoE power supply, providing a convenient and efficient way to power the device over Ethernet. This option simplifies the installation process and reduces the amount of cabling required, making it an ideal solution for applications with limited power sources or where power outlets are not readily available.
- PoE PD: IEEE 802.3at, 25.5W Max
Note: It's worth noting that the PoE module provided with the reComputer Industrial R2000 is compliant with the IEEE 802.3at standard and can provide a maximum power supply of 25W. Therefore, if there is a need to connect high-power peripherals such as 5G or 4G modules, the PoE power supply may not be sufficient. In this case, it's recommended to use the DC terminal for power supply instead to ensure stable and reliable operation of the device.
Power Consumption
The reComputer Industrial R2000 does not come with a power button by default, and the system will automatically start up once power is connected. When shutting down, please select the shutdown option in the operating system and wait for the system to fully shut down before cutting off power. To restart the system, simply reconnect to the power.

LED Indicator Status
The reComputer Industrial R2000 features 4 LED indicators that serve to signal the machine's operational status. Please refer to the table below for the specific functions and status of each LED:
| Name | Color | Status | Description |
|---|---|---|---|
| PWR | Green | On | The device has been connected to power. |
| Off | The device is not connected to power. | ||
| ACT | Orange | On | Under Linux this pin will flash to signify eMMC access. If any error occurs during booting, then this LED will flash an error pattern which can be decoded using the look up table( Raspberry Pi Documentation - Configuration) on the Raspberry Pi website. |
| USER | Green/Red/Blue | Need to be defined by user. | |
| 4G/5G | Green | On | The dial-up is successful and the connection is normal. |
| Off | 4G/5G signal is not connected or the device is not powered on. |
ACT Status table
| Long flashes | Short flashes | Status |
|---|---|---|
| 0 | 3 | Generic failure to boot |
| 0 | 4 | start*.elf not found |
| 0 | 7 | Kernel image not found |
| 0 | 8 | SDRAM failure |
| 0 | 9 | Insufficient SDRAM |
| 0 | 10 | In HALT state |
| 2 | 1 | Partition not FAT |
| 2 | 2 | Failed to read from partition |

UPS (Uninterruptible Power Supply) Module
The UPS is 7F, which operates in series. The UPS module is positioned between the DC5V and CM5 components, with a GPIO signal utilized to alert the CPU in the event of a power loss from the 5V supply. Upon receiving this signal, the CPU executes an urgent script before the super capacitor's energy is depleted, initiating a "$ shutdown" command. The backup duration provided by the UPS heavily relies on the system load. Below are some typical scenarios tested with a CM5 module featuring 4GB RAM, 32GB eMMC storage, and a Wi-Fi module.
| Mode of Operation | Time(s) | Remark |
|---|---|---|
| Idle | 15 | Testing under idle conditions with official driver program loaded |
| Full load of CPU | 6 | stress -c 4 -t 10m -v & |
