Before You Begin: What You'll Need
Configuring an Antminer Z15 or Z15 Pro is straightforward once you have the right prerequisites in place. Before powering on your machine, gather the following: a dedicated 20A circuit (Z15 Pro draws up to 3,300W — standard 15A household circuits are insufficient), a quality surge-protected power strip, an Ethernet cable, a router with DHCP enabled, a computer on the same local network, and your Zcash mining pool credentials (URL, username, password). Having everything ready before powering on will make the process smooth and reduce the risk of tripping breakers or corrupting the miner's NAND storage.
The Antminer Z15 series uses a standard Bitmain web interface. The stock firmware works well for pool mining, and unless you have specific reasons to flash third-party firmware (like Braiins OS for better efficiency tuning), stick with the official firmware for your first setup.
Step 1 — Physical Setup and Power-On
Unbox your Antminer and inspect it for shipping damage. The Z15 Pro ships in a foam-lined box and should arrive with the PSU and power cables included (some bundles do not — verify before ordering). Place the miner in a well-ventilated area: the unit runs hot (fans peak at 6,300 RPM) and needs at least 30 cm of clearance at both the intake and exhaust ends.
Connect the Ethernet cable first, then plug in power. The miner will boot automatically — the green LEDs on the hash boards will cycle through an initialisation sequence. Allow 2–3 minutes for the miner to fully boot before attempting to access the web interface. During boot, the fans will ramp to full speed briefly, then settle into a working frequency. This is normal.
Step 2 — Finding Your Miner's IP Address
The Antminer uses DHCP by default, meaning your router assigns it an IP address automatically. To find it:
- Log into your router's admin panel (usually
192.168.1.1or192.168.0.1) - Look for the DHCP client list or connected devices table
- Find a device named something like
antmineror with a Bitmain MAC address prefix (B8:27:EBorEC:DA:3B) - Note the assigned IP (e.g.,
192.168.1.105)
Alternatively, you can use a network scanner like Angry IP Scanner or Advanced IP Scanner to find all devices on your subnet. Once you know the IP, open it in your browser.
Pro tip: Reserve this IP in your router's DHCP settings so the miner always gets the same address. This makes monitoring and remote access much easier.
Step 3 — Accessing the Web Interface
Open a browser and navigate to your miner's IP address (e.g., http://192.168.1.105). You'll be prompted for a login. The default credentials for Bitmain Antminers are:
- Username: root
- Password: root
Change this password immediately after logging in via System → Administration → Password. A compromised miner can be redirected to an attacker's pool, losing you all earnings silently.
The dashboard shows your current hashrate, temperature readings for each hash board and chip, fan RPM, and accepted/rejected share counts. On first boot, the pool fields will be blank or contain default values.
Step 4 — Configuring Your Pool Settings
Navigate to Miner Configuration → General Settings (or Miner → Mining Pools depending on firmware version). You'll see three pool slots. Configure Pool 1 with your primary pool:
| Field | Example (F2Pool) | Example (2Miners) |
|---|---|---|
| Pool URL | stratum+tcp://zec.f2pool.com:3333 | stratum+tcp://zec.2miners.com:2020 |
| Worker | yourusername.worker1 | yourusername.worker1 |
| Password | x (or 123) | x |
Add a backup pool in Pool 2 (e.g., use 2Miners as backup if your primary is F2Pool). Pool 3 can remain as a tertiary fallback. Having multiple pools configured ensures mining continues if the primary pool experiences downtime — Zcash pool uptime is generally excellent, but outages do occur during high-traffic periods.
The worker name format is poolusername.workerlabel. The label after the dot can be anything — common choices are "w1", "rig1", or a location identifier like "home1". Pool usernames are typically your pool account email or wallet address depending on the pool type.
Step 5 — Saving Settings and Verifying Shares
Click Save & Apply. The miner will restart its mining processes (this takes 30–60 seconds). Return to the dashboard and watch the Real-time Hashrate graph — it should climb from zero and stabilise near the miner's rated hashrate within 2–5 minutes. The Z15 Pro should show approximately 620,000 Sol/s at stock settings.
Log into your pool account's dashboard and navigate to the Workers tab. Your worker should appear within 3–5 minutes with a green "online" indicator. Check that Accepted Shares are climbing — this confirms your configuration is correct and earnings are accumulating.
Step 6 — Temperature and Fan Monitoring
Hash board temperatures should sit between 65°C and 80°C under load. If any board exceeds 85°C, check airflow: ensure intake and exhaust are unobstructed and ambient temperature is below 35°C. The Z15 Pro's three hash boards each contain 84 BM1746 chips. A single hot board that consistently reads 5–10°C above the others may indicate a partially failed chip or inadequate thermal paste — contact Bitmain support if this persists after improving airflow.
Fan speeds are automatically controlled by the firmware based on temperature. Do not cover or slow the fans manually. At 620 KSol/s, expect noise levels around 75 dB — comparable to a vacuum cleaner. Home mining the Z15 Pro requires a dedicated space with good insulation or soundproofing if noise is a concern.
Frequently Asked Questions
A small percentage of rejected shares (under 1%) is normal — these occur due to network latency or stale shares found at the same time as the pool solved a block. If rejection rate exceeds 2%, check your pool URL for typos, try switching to a geographically closer pool server, or reduce your network round-trip time.
Download the latest firmware from Bitmain's official support page for your specific model. In the web interface, go to System → Upgrade, upload the .tar.gz file, and follow the prompts. Never power off during a firmware update — this can brick the miner. Always back up your pool configuration first.
Yes — most home routers support 30+ DHCP clients. For larger setups (10+ miners), use a managed switch to segment traffic. Ensure each miner has adequate Ethernet cable length and that your router's DHCP lease table doesn't run out of available IPs.
