The Z15 mines Zcash (ZEC) and other Equihash-algorithm coins, making it distinct from the SHA256-based S-series. When your Z15 loses network visibility, fails to detect hashboards through its 4-port interface, or becomes stuck in boot loops, a control board replacement restores full mining operation.\u003c\/p\u003e\n\u003ch3\u003eAntminer Z15 Control Board Specifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\" cellspacing=\"0\" cellpadding=\"10\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"background-color: #f2f2f2;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"background-color: #f2f2f2;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Model\u003c\/td\u003e\n\u003ctd\u003eAntminer Z15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHashboard Ports\u003c\/td\u003e\n\u003ctd\u003e4 ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCategory\u003c\/td\u003e\n\u003ctd\u003eControl Board \/ Motherboard \/ PCBA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAlgorithm\u003c\/td\u003e\n\u003ctd\u003eEquihash (Zcash \/ ZEC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePCB PCBA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eContact our sales team for current stock status\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eZ15 4-Port Hashboard Interface \u0026amp; Diagnostics\u003c\/h3\u003e\n\u003cp\u003eThe Z15's 4-port configuration connects to its four dedicated hashboards. If one or more ports stop detecting hashboards, the issue may originate from the control board's port circuitry rather than the hashboard itself. Before replacing the entire board, verify individual hashboard health by testing each one across different ports. If all ports fail simultaneously, the control board is the confirmed failure point.\u003c\/p\u003e\n\u003ch3\u003eZ15 Control Board Replacement \u0026amp; Component-Level Repair\u003c\/h3\u003e\n\u003cp\u003ePower down the miner, disconnect all four hashboard ribbon cables and the Ethernet connection, then swap the board.
