Control Board Installation & Firmware Setup
After swapping the board, the miner should boot and acquire a network address via DHCP. If firmware needs updating, use the SD card slot to flash the latest version for your model. For CV1835 chip-level repairs on the control board itself, the CV1835 Tin Tool provides the stencil for processor replacement. The SMBJ15CA TVS Diode protects the control board's power input from voltage transients. For Antminer L9 miners that also use the CV1835 platform, the Antminer L9 CV1835 Control Board (CB8) provides the L9-specific variant.
