When the original board fails — whether from a corrupt NAND, a dead Ethernet PHY, or a voltage-regulator fault — the miner loses all communication with the hash boards and drops offline. This \u003cstrong\u003ereplacement PCBA motherboard\u003c\/strong\u003e is tested for direct compatibility with the Jasminer X4 1U chassis, restoring full operational control without reflashing or reconfiguring firmware.\u003c\/p\u003e\n\u003ch3\u003eCommon Control Board Failure Symptoms\u003c\/h3\u003e\n\u003cp\u003eA failing Jasminer X4 control board typically presents as one of three patterns: the miner powers on but never appears on the network (Ethernet PHY or CPU failure), the dashboard loads but reports zero hash boards detected (data-bus fault), or the unit reboots in a loop (corrupted boot partition or failed RAM). If you have confirmed the PSU voltages are within spec and the hash boards test good on a known-good miner, the control board is the remaining fault point.\u003c\/p\u003e\n\u003ch3\u003eInstallation and Verification\u003c\/h3\u003e\n\u003cp\u003ePower down the miner and disconnect all cables. Remove the mounting screws holding the original control board, unplug the hash board ribbon cables and fan headers, and slide the board out. Install the replacement in the same orientation, reconnect all cables, and secure the screws. On first boot, access the miner's web dashboard via its IP address to verify that all hash boards are detected and the miner begins hashing at its rated speed. Update the firmware to the latest Jasminer release if prompted.\u003c\/p\u003e\n\u003ch4\u003eJasminer X4 Control Board Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eProduct Name\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eJasminer X4 Control Board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCategory\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eControl Board \/ PCBA \/ Motherboard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eJasminer X4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eHigh-quality PCB PCBA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e0.2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eConfirm with sales team\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated Control Boards \u0026amp; Miner Motherboards\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/jasminer-x16p-x16q-control-board\"\u003eJasminer X16P \/ X16Q Control Board\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/innosilicon-a10pro-8g-control-board-pcba-replacement-part-controller\"\u003eInnosilicon A10 Pro 8G Control Board\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/goldshell-kd5-control-board-pcba-replacement-brand-new-controller\"\u003eGoldshell KD5 Control Board PCBA\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/innosilicon-a11-a11mx-control-board-pcba-replacement-part-controller\"\u003eInnosilicon A11 \/ A11MX Control Board\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNeed control boards for multiple Jasminer units? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for availability and volume pricing.\u003c\/p\u003e\n\u003cp\u003eWorldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"Default Title","offer_id":42308703453363,"sku":null,"price":149.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/Jasminer-X4-High-Quality-Control-Board-Reliable-Crypto-Miner-Performance-Longevity.webp?v=1744590077","url":"https:\/\/lys-sz.com\/products\/jasminer-x4-cryptominer-control-board","provider":"LYS Shenzhen","version":"1.0","type":"link"}
