Antminer L9 — models & specifications
Manufacturer-rated values; they vary by batch and work mode. AntminerTools reads live values directly from each unit.
| Model | Hashrate | Power | Cooling |

| Antminer L9 Hyd. 2U | 27 GH/s | 5670 W | Hydro |
| Antminer L9 | 17–18.5 GH/s | 3360 W | Air |
How to monitor your Antminer L9
Run the lightweight connector agent on any PC or Raspberry Pi on your farm's network, click Scan, and every Antminer L9 on your subnet appears automatically — model, worker name, serial and MAC included. From then on it's live stats every 30 seconds.
Everything you get for your Antminer L9
Running the Antminer L9 day to day — what to watch
Antminer L9 rigs mine Scrypt (Litecoin + Dogecoin merged mining). Specs tell you what the machine can do; day-to-day monitoring is about noticing early when it stops doing it. Here is what experienced operators watch on this model, and how to automate it.
Temperatures and cooling
The L9 roughly doubles L7 output per unit. Same thermal rules apply — chips under 80 °C sustained, 85 °C alert as the hard line — but per-unit stakes are higher, so a dead L9 hour hurts twice as much.
Power, efficiency and what they cost
Across the variants above, efficiency works out to roughly 182–210 J/GH at wall power — the Antminer L9 is the efficiency leader of the family. At $0.06/kWh, every 100 W of extra draw costs about $4.30 a month, which is why the dashboard tracks efficiency per unit and not just raw hashrate.
The signals that matter
Because a single L9 replaces two L7s, offline minutes are the metric to optimize. The offline alert fires after about a minute of missed polls; pair it with the auto-restart rule so hung units recover before you have read the email.
If an L9 shows healthy hashrate but zero Dogecoin-side rewards, verify the pool supports merged mining — the miner cannot report what the pool does not do.
Recommended alert setup for the Antminer L9: a high-temperature rule at 85 °C chip temp, a hashrate-zero rule with auto-restart (a ten-minute boot grace stops false alarms after reboots), and an offline rule that emails you about a minute after a unit stops answering. All three take under a minute to create in Alerts — see the docs for details, or the guide to monitoring your fleet remotely.
Antminer L9 monitoring — frequently asked questions
How do I monitor my Antminer L9 remotely?
Create a free farm, run the connector agent on any PC or Raspberry Pi on the same network as your Antminer L9, then hit Scan. You'll see live hashrate and temperatures within a minute, from anywhere — no port forwarding, no VPN, no static IP.
Can I see Antminer L9 temperatures and get overheat alerts?
Yes. AntminerTools reads per-chain chip and PCB temperatures every 30 seconds and can automatically put an Antminer L9 to sleep if it overheats, plus email you on the Unlimited plan.
Does it work with every Antminer L9 variant?
Yes — every Antminer L9 running stock Bitmain firmware with the standard web interface is supported, including Hydro and immersion variants, with special handling for water-cooled temperature sensors.
How much does Antminer L9 monitoring cost?
Free for 1 farm and up to 4 miners with full monitoring and remote control. Paid plans add capacity from $3/mo, and email alerts + remote desktop on Unlimited.
