Function Description

The AvalonMiner1246 is a cryptocurrency mining device designed for efficient operation. It supports two primary working modes: "normal mode" and "configuration mode." In normal mode, the device operates using either DHCP (dynamic acquisition) or static IP for network connectivity, with DHCP being the factory default. Configuration mode, accessible during startup, allows users to set a static IP address (defaulting to 192.168.168.168 with subnet mask 255.255.255.0) and configure network, mining pool, and password settings via a built-in web interface.

The device features a control board with various connection points for essential components. It connects to a network via a dedicated port and uses 4-pin fan extension cables for fan connections. Power is supplied to the control board via a 6-pin cable. Hash boards are connected to the control board using 2x 7-pin cables.

The control board includes several buttons and indicator LEDs for user interaction and status monitoring. The "RESET" button performs a system reset without affecting network settings. The "FUNC" button offers multiple functionalities, including restoring factory configurations, entering configuration mode, and switching the LED light status during operation.

Important Technical Specifications

  • Enter by pressing the FUNC button during the second red LED flash (approx. 3 seconds) at miner startup.
  • IP address is static: 192.168.168.168, subnet mask: 255.255.255.0.
  • Access web interface via PC browser to configure network, mining pool, and password.
  • To access, set PC static IP to 192.168.168.100 (or any non-conflicting address in the same network segment) with subnet mask 255.255.255.0. Connect PC directly or via the same switch/router.

System Setting:

• Access the device's built-in web service through a browser.
• Login with default username root and password root to view the Overview page.

Network Setting:

• Click "Network" in the console to set DHCP or static IP.
• A restart is required after saving network settings (via reboot button or power cycle).

Pool Setting:

• Configure mining pool settings (address, worker, password).
• Select "Normal mode" (normal/low power consumption) or "High performance" (high power consumption). High performance requires a power supply with higher output.
• A restart is required after saving pool configurations.

User Password:

• Change the default password (root) via the "administrator" option in the console.

Firmware Upgrade:

• Firmware files are in *.AUP format, available from the official website or customer service.
• Upgrades can also be performed using FMS software.
• In FMS, select the miner and click "upgrade." Choose the .AUP file and click "open."
• Successful upgrades will be confirmed; failed upgrades will list affected IP addresses. Failed miners can be restarted via the "Restart" button in FMS and re-upgraded.

Restore to Factory Setting:

• Method 1: With the miner powered off, press and hold the FUNC key, then power on. Keep FUNC pressed until the red LED flashes.
• Method 2: With the miner powered on, press and hold the FUNC key. While holding FUNC, press and release the RESET button. Keep FUNC pressed until the red LED flashes.
• After restoring, the system will clear saved configurations (network, mine pool, password). The white indicator light will flash frequently, confirming success. Release FUNC, then press RESET or power cycle to restart with default settings.

Malfunction Troubleshooting:

Boot Failure:

1. Phenomenon: Fan does not turn or LED light does not light up after starting.
2. Possible Causes: Loose fan wiring, disconnected miner control board power supply, poor AC power input, broken power module, broken control board, power output short circuit protection.
3. Inspection and Repair:
   • Power on the miner, turn on the power switch, and plug in the network cable. Check if the network port link light flickers.
     • If the network port light is off, the MM control board has no power. Check power line connection, replace power supply, or check for short circuit in power output.
     • If the network port light is on but the MM control board LED is off, replace the MM control board.
   • If the MM control board LED is on but the fan does not rotate, check fan connection or replace the fan.

Cannot Mine:

1. Phenomenon:
   • Unable to connect to the pool for a long time (over 5 minutes) after startup (miner lights yellow for a long time, no green light, no hashrate).
   • Miner connects to the pool after startup (LED green), but has no hashrate.
2. Possible Causes: Pool configuration error, network configuration error, miner cannot access the Internet, miner power supply has no main circuit output (wiring error, overload, short circuit, damage), miner's hashboard not working, overheat protection.
3. Check and Repair:
   • If PC cannot connect to miner via network: Try restoring factory settings (Appendix I) after confirming network environment, cable connection, and normal miner startup.
   • Check current firmware version and update to the latest with FMS (Appendix 3).
   • Check hashboard status in the log. If "overheating shutdown," check fan and ambient temperature.
   • Check the number of hash boards shown in the figure. If 1 or 2, contact after-sales. If 0, check power supply status.

Log Page Parameters (Appendix 4):
