In September 2020, Canaan announced the Canaan Avalon1246 bitcoin mining machine.  Avalon1246 mining machine is the eleventh generation of Avalon series mining machine with nearly ten years of research and development and production experience of Jiannan Technology.  

Avalon1246 Bitcoin Mining machine Avalon1246  

The hash rate is 90TH/s  

Power is 3420 w  

The energy efficiency ratio is 38J/Th  

The following cloud bits to bring you the latest :

One, open the box exposure  

A1246 adopts five-layer extra-hard packing case, and the pearl board is suspended for encapsulation, which has a good shockproof effect.  Various compliance information is printed on the packing boxes.  

• The miner has the Avalon logo on the other side.

There are two fans (12V4.5a) with a diameter of 12CM and a four-pin jack in the front and a protective cover, from which the air enters.  
At the top of the mining machine is the controller. The controller adopts the independently developed Kanzhi K210 dual-core 64-bit AI chip, which is widely used in intelligent electronic equipment. The main control chip has built-in encryption algorithm to protect against anti-theft.  

• Bottom of mining machine.

Two, installation and debugging  

Before the installation, make the following preparations.  

1. Each mining machine has its own high-quality RJ45 interface network cable, and the data transmission of the network cable is prone to interference, affecting the stability.  

2. The operation power of A1246 large computing power mining machine is relatively high, reaching more than 3000W. The mining machine is equipped with a 16A power line.  It is necessary to provide a socket with 16A socket. Since the mining machine runs for a long time and the power interface heats up for a long time, please choose the socket with reliable quality from the compliant manufacturer.  

3. Some logistics violence is inevitable in the process of mining machine transportation. Before installing the mining machine, pick up the mining machine and shake it slightly to detect whether there is abnormal sound inside the mining machine.  

Installation of A1246 is very simple, connect network cable and power supply.  

Mining machines can be set up in two ways. The first way is to use the official cluster management software (supporting batch configuration of mining machines).  Download the software and instructions from https://canaan-creative.com/service/a10

The second is to use the browser of the Internet access device (mobile phone, computer) in the LAN to enter the background of the mining machine for setting.  

After the mining machine is started by default, the IP address is automatically assigned. The latest IP device connected to the LAN is the mining machine. Open a browser and enter the IP address of the mining machine to enter the background of the mining machine. 

First come to the login page, you can see avalon logo and password login box, default factory user name and password are "root".

Four, the test  

This evaluation is located in the southern region. In recent days, the high temperature has continued, and the outdoor temperature in the daytime is nearly 30 degrees, which also simulated a mining environment in summer for the mining machine evaluated this time.  

A1246 operates without frequency, voltage, fan speed and other complex Settings, has been done plug and play level.  

After the mining machine is started, the calculation force reaches 90T in a short time, the fan speed is about 6800r, and the average calculation force is 90.05T in the long run.  The maximum calculation force is nearly 105T, and the minimum calculation force is about 78T.  

Under normal working condition, the calculation force is about 90T, and the measured power is about 3508W. 

In terms of temperature, when the background temperature shows 31 degrees inside the mining machine, the air inlet is measured at 26.3 degrees

• The air outlet measured 28 degrees.

5, summary  

1.Avalon1246 mining machine solid work, its own power supply, mining machine can be placed in horizontal and vertical convenient large-scale mine deployment, 90T large computing power, smaller space deployment of greater computing power.  

2. Extremely simple installation, plug and play, one-step setting, a large number of mining machines can cooperate with cluster software, convenient operation and maintenance.  

3. The controller has built-in AI chip with strong security performance. Combined with the operation system, it can automatically identify malicious viruses and prevent the mining machine from stealing computing power.  

4. Stable operation, high efficiency heat dissipation of front and rear fans, self-adjusting mining guardian system, long time operation power of 90T, the same as the official parameters.  

5. Ultra-low energy consumption ratio, high performance 38.8J/T energy consumption ratio is in the international leading position.  

6. The Avalon1246 provides an impressive mining experience, simple operation and excellent operational stability.
