Learn how to connect a Bitmain Antminer to PECPool, find the miner’s IP address, access its management interface, configure three PECPool stratum servers, create a unique worker name, verify accepted shares, and troubleshoot common connection problems.

Bitmain Antminer devices can connect directly to PECPool using the miner’s built-in web management interface.

You do not need to install mining software on a separate computer. After entering the PECPool stratum addresses and your worker information, the Antminer connects to the pool and begins submitting Bitcoin mining shares automatically.

This guide applies to Bitcoin SHA-256 Antminer devices, including many models from the Antminer S and T series. Menu names and interface layouts may vary slightly depending on the model and firmware version.

What You Need Before Starting

Before configuring your Antminer, make sure you have:

• A Bitcoin-compatible Bitmain Antminer
• A suitable power supply and electrical connection
• An Ethernet network connection
• A router or network switch
• A computer connected to the same local network
• Access to the Antminer management interface
• A PECPool account
• Your PECPool mining account name
• The recommended PECPool stratum addresses

Antminers normally use a wired Ethernet connection. Connect the miner directly to a router or network switch using a reliable network cable.

Before powering on the miner, verify that:

• The miner is installed in a properly ventilated location.
• The power voltage matches the miner and power supply requirements.
• All power connectors are fully inserted.
• The Ethernet cable is connected securely.
• Air intake and exhaust areas are not blocked.
• The miner is protected from excessive dust, moisture, and heat.

Incorrect voltage, loose power cables, poor ventilation, or blocked fans may damage the device.

Step 1: Find Your PECPool Mining Account

Sign in to the official PECPool control panel:

• https://cp.pecpool.com
• https://cp.pecpool.cc

Open the Accounts section and locate the mining account that you want to use.

Your mining account name will be used in the Antminer’s Worker field.

The mining account is not the same as:

• Your email address
• Your Bitcoin wallet address
• Your PECPool password
• The Antminer administrator username
• The miner serial number

Copy the account name exactly as displayed in the panel.

If you manage multiple mining accounts, make sure you select the correct account before configuring the miner.

Step 2: Choose a Worker Name

A worker name identifies an individual Antminer under your PECPool mining account.

The recommended format is:

AccountName.WorkerName

Example:

myaccount.antminer01

For multiple Antminers, use a different worker name for every device:

• myaccount.antminer01
• myaccount.antminer02
• myaccount.antminer03

You may also name workers based on their physical location:

• myaccount.rack01a
• myaccount.room2miner05
• myaccount.siteb01

Use short and recognizable names. Avoid spaces and unnecessary special characters.

Using a unique worker name for each Antminer allows you to monitor its hashrate, uptime, accepted shares, connection status, and possible problems separately.

The worker will normally be created automatically in PECPool after the miner begins submitting valid shares. You do not usually need to create it manually in advance.

Step 3: Connect the Antminer to Your Network

Connect an Ethernet cable from the Antminer to your router or network switch.

Then connect the required power cables and turn on the miner.

Wait until the control board has completed its startup process. Depending on the model and firmware, this may take several minutes.

The miner and the computer used for configuration must normally be connected to the same local network.

For example:

• Router: 192.168.1.1
• Computer: 192.168.1.20
• Antminer: 192.168.1.100

The exact addresses on your network may be different.

Step 4: Find the Antminer IP Address

You need the Antminer’s local IP address to open its management interface.

Several methods can be used.

Method 1: Use Bitmain IP Reporter

Bitmain provides the IP Reporter utility for locating supported Antminer devices on a local network.

General process:

1. Download IP Reporter from the official Bitmain support website.
2. Extract the downloaded file.
3. Run the utility as Administrator.
4. Click Start in IP Reporter.
5. Press and hold the IP Report button on the Antminer control board.
6. Release the button after the miner responds or beeps.
7. The miner’s IP address should appear in the IP Reporter window.

Your computer and Antminer must be connected to the same network for this method to work.

Method 2: Check the Router

Open your router or DHCP server management page and view the connected devices or DHCP client list.

Look for a device identified as:

• Antminer
• Bitmain
• The miner’s MAC address
• An unknown device that recently connected

Method 3: Use a Network Scanner

A trusted local network scanner can also be used to find active devices.

Before using this method, make sure the software is obtained from a reputable source and is used only on a network you are authorized to manage.

Step 5: Open the Antminer Management Interface

Enter the miner’s IP address in a web browser.

Example:

http://192.168.1.100

A login window should appear.

On some factory-default Antminer firmware versions, the default credentials may be:

• Username: root
• Password: root

However, credentials may vary depending on:

• Antminer model
• Firmware version
• Previous configuration
• Hosting provider
• Device supplier
• Custom firmware

Use the credentials provided with your miner or set by your network administrator.

After signing in, change the default administrator password whenever the firmware provides that option. Do not expose the Antminer management page directly to the public internet.

Step 6: Open the Pool Configuration

The pool settings menu may have a different name depending on the Antminer model and firmware.

Common names include:

• Miner Configuration
• Mining Settings
• Pool Configuration
• Settings
• Pool
• Configuration

Open the section that contains the following fields:

• Pool URL
• Worker
• Password

Most Antminers provide three separate pool configurations:

• Pool 1
• Pool 2
• Pool 3

Bitmain uses these entries as priorities. The miner normally connects to Pool 1 first. If Pool 1 becomes unavailable, it can switch to Pool 2 and then Pool 3.

PECPool recommends configuring all three stratum addresses to reduce mining interruptions and provide a backup connection.

Step 7: Select PECPool Stratum Servers

PECPool provides regional Bitcoin stratum servers.

Select the nearest and most stable server as Pool 1, then configure alternative addresses as Pool 2 and Pool 3.

PECPool Bitcoin Stratum Servers

The complete address format is:

stratum+tcp://server-address:port

Example:

stratum+tcp://btc-eu.pecpool.com:3333

Use the server order recommended in the PECPool panel for your location whenever available.

Step 8: Enter the Pool Information

Enter one PECPool server in each Pool URL field.

Use the same PECPool mining account and worker name for all three pool entries.

Example for Europe

Pool 1

URL

stratum+tcp://btc-eu.pecpool.com:3333

Worker

myaccount.antminer01

Password

x

Pool 2

URL

stratum+tcp://btc.pecpool.com:443

Worker

myaccount.antminer01

Password

x

Pool 3

URL

stratum+tcp://btc-us.pecpool.com:25

Worker

myaccount.antminer01

Password

x

Example for Iran

Pool 1

URL

stratum+tcp://btc.pecpool.cc:8443

Worker

myaccount.antminer01

Password

x

Pool 2

URL

stratum+tcp://btc-as.pecpool.com:443

Worker

myaccount.antminer01

Password

x

Pool 3

URL

stratum+tcp://btc-eu.pecpool.com:3333

Worker

myaccount.antminer01

Password

x

The Pool Password field is not your PECPool login password.

Never enter any of the following in the pool password field:

• Your PECPool account password
• Your email password
• Your 2FA code
• Your Bitcoin wallet private key
• Your wallet seed phrase

When no special pool password is required, x can be used as the standard placeholder.

Step 9: Save the Configuration

Carefully review all three pool entries.

Make sure:

• The word stratum is spelled correctly.
• The server address is correct.
• The port number is correct.
• The account name is correct.
• The worker name is included.
• There are no spaces before or after the values.
• The wallet address has not been entered instead of the account name.

Click one of the following buttons, depending on the firmware:

• Save
• Apply
• Save & Apply
• Submit

Some Antminers restart the mining process automatically after saving. Other firmware versions may require a manual restart.

Do not repeatedly power the miner off and on while it is applying the configuration.

Step 10: Check the Antminer Status

Open the Antminer status page after saving the configuration.

The page may be named:

• Dashboard
• Miner Status
• Overview
• Mining Status
• Kernel Log
• Log

Allow several minutes for the miner to initialize the hashboards and establish a pool connection.

Check the following items:

Pool Status

The selected PECPool server should appear as:

• Alive
• Connected
• Active
• Working

The exact status name depends on the firmware.

Hashrate

The Antminer should begin displaying hashrate after the hashboards initialize.

Do not evaluate the miner only from the first few minutes. Average hashrate is more useful than a rapidly changing real-time value.

Accepted Shares

The accepted share counter should begin increasing after a successful connection.

This is one of the most important signs that the Antminer is mining correctly.

Rejected Shares

A small number of rejected or stale shares may occasionally occur.

A consistently high rejection rate should be investigated.

Hashboards

Verify that all expected hashboards or chains are detected.

For example, if the model contains three hashboards, the status page should normally display all three.

Temperature and Fans

Check that:

• Fans are operating.
• Temperature values are visible.
• The miner is not overheating.
• Fan speed is not repeatedly changing without reason.
• The miner is not entering sleep or protection mode.

Step 11: Verify the Worker in PECPool

Return to the PECPool panel and open Monitor.

Select the mining account used in the Antminer configuration.

After the miner begins submitting valid shares, the worker should normally appear in the panel within approximately 10 to 20 minutes.

Check:

• Worker name
• Online status
• Current hashrate
• One-hour hashrate
• Twenty-four-hour hashrate
• Last share time
• Accepted shares
• Rejected or stale shares
• Hashrate chart

The hashrate shown in PECPool may initially differ from the hashrate displayed in the Antminer interface.

This is normal because:

• The Antminer shows a local device estimate.
• PECPool calculates hashrate from valid shares received over time.
• A recently started miner does not yet have enough share history.
• Short-term share submission is naturally variable.

Allow sufficient time for the pool average to stabilize.

Understanding the Three Pool Entries

The three Pool fields are not used simultaneously for normal mining.

The Antminer normally uses them in priority order:

1. Pool 1 is the primary connection.
2. Pool 2 is used if Pool 1 cannot be reached.
3. Pool 3 is used if both Pool 1 and Pool 2 are unavailable.

When Pool 1 is working normally, Pool 2 and Pool 3 may appear inactive, standby, dead, or unused depending on the firmware.

This does not necessarily indicate a problem.

The important point is that the miner can connect to each backup server when required.

Common Antminer Connection Problems

The Antminer IP Address Cannot Be Found

Check the following:

• The Ethernet cable is connected.
• The router or switch port is active.
• The miner has completed startup.
• The miner and computer are on the same network.
• IP Reporter is running as Administrator.
• The IP Report button is pressed correctly.
• DHCP is enabled on the router.
• A different Ethernet cable or switch port works.

Also check the router’s DHCP client list.

If the miner previously used a static IP address from another network, it may not receive a new address automatically.

A factory reset may be required in some situations, but this should only be performed after recording existing settings and reviewing the correct procedure for the exact Antminer model.

The Antminer Login Page Does Not Open

Possible causes include:

• Incorrect IP address
• Computer and miner located on different subnets
• Browser cache
• Local firewall restrictions
• Duplicate IP addresses
• Static IP configured incorrectly
• Control board startup failure

Try:

1. Ping the miner’s IP address.
2. Open the page using both http:// and https:// if supported.
3. Test another browser.
4. Test another computer on the same network.
5. Check the subnet mask and gateway.
6. Confirm that no other device is using the same IP.

Pool Status Shows Dead

A Dead pool status means the Antminer cannot establish or maintain a connection to the selected server.

Check:

• Stratum address
• Port number
• Internet access
• DNS resolution
• Router firewall
• Network filtering
• Regional server availability
• Miner date and time
• Firmware stability

Try another official PECPool server or port.

For example, if port 3333 is restricted, try port 443 or another supported port for the selected region.

Do not use unofficial server addresses received through private messages.

Pool Status Shows Alive but Shares Are Not Accepted

If the server is reachable but no accepted shares appear, check:

• Account name
• Worker format
• Miner algorithm
• Hashboard status
• Miner logs
• Password field
• ASIC initialization
• Frequency and voltage settings

Confirm that the Antminer is a Bitcoin SHA-256 model.

An Antminer designed for a different mining algorithm cannot mine Bitcoin simply by changing the pool address.

Authorization Failed

Authorization problems are commonly caused by:

• Incorrect PECPool mining account
• Missing worker name
• Incorrect separator
• Spaces in the Worker field
• Wallet address entered as the Worker
• Copying an incomplete account name
• Unsupported characters
• Using the wrong account

Use the worker format shown by PECPool:

AccountName.WorkerName

Example:

myaccount.antminer01

The Worker Is Offline but the Antminer Is Running

A powered-on Antminer is not necessarily connected to the pool.

The worker may remain offline if PECPool is not receiving valid shares.

Check:

• Pool status
• Accepted shares
• Account name
• Worker name
• Internet connection
• Last share time
• Hashboard status
• Miner logs
• Temperature
• Restart history

After correcting the configuration, wait approximately 10 to 20 minutes for the worker status to update.

The Pool Hashrate Is Lower Than the Antminer Hashrate

Temporary differences are expected.

Possible reasons include:

• The Antminer was recently started.
• The miner was recently restarted.
• The pool has not received enough shares yet.
• Network latency is high.
• Shares are being rejected.
• The miner is restarting intermittently.
• One or more hashboards are unstable.
• The miner is overheating.
• Overclocking settings are unstable.

Review the one-hour and twenty-four-hour averages rather than only the current value.

Rejected Shares Are High

Possible causes include:

• High network latency
• Packet loss
• Unstable internet
• Distant stratum server
• Frequent reconnections
• Unstable custom firmware
• Excessive overclocking
• Incorrect frequency or voltage
• Hardware errors
• High temperature

To reduce rejected shares:

1. Select a closer PECPool server.
2. Test another official port.
3. Check packet loss.
4. Inspect network cables and switches.
5. Return overclocking settings to a stable level.
6. Review the Antminer kernel log.
7. Update only to trusted and compatible firmware.

One or More Hashboards Are Missing

This is normally a hardware or firmware issue rather than a PECPool connection problem.

Check:

• Power connectors
• Signal cables
• Power supply output
• Hashboard detection
• ASIC chip count
• Kernel log
• Temperature
• Firmware compatibility

Do not continue restarting the miner repeatedly if a hardware fault is suspected.

Follow the official Bitmain troubleshooting procedure for the exact model or contact a qualified repair technician.

The Miner Repeatedly Restarts

Frequent restarts may be caused by:

• Unstable electrical power
• Insufficient power supply capacity
• High temperature
• Fan failure
• Firmware problems
• Hashboard faults
• Network watchdog settings
• Aggressive overclocking
• Loose power connectors

Review the kernel log and power environment before assuming the mining pool is responsible.

Recommended Antminer Security Practices

After completing the setup:

• Change the default miner administrator password.
• Do not forward the Antminer web interface directly to the internet.
• Do not expose ports 80, 443, or 22 without a secure access design.
• Use a trusted VPN for remote management.
• Install firmware only from trusted sources.
• Back up important network and pool settings.
• Keep your PECPool password separate from the miner password.
• Never share your PECPool 2FA code.
• Never enter a wallet seed phrase into an Antminer.
• Restrict access to the mining network.
• Change passwords when staff or service providers change.

The Antminer management password only protects the local miner interface. It is separate from the PECPool account password.

Final Configuration Checklist

Before considering the Antminer setup complete, confirm that:

• The Antminer is connected by Ethernet.
• The miner has a valid local IP address.
• You can open its management interface.
• The default administrator password has been changed.
• The correct PECPool mining account is used.
• The worker name is unique.
• Pool 1 contains the preferred regional server.
• Pool 2 and Pool 3 contain backup servers.
• All server addresses and ports are correct.
• The pool password is not your PECPool login password.
• The Antminer shows an active pool connection.
• All expected hashboards are detected.
• Accepted shares are increasing.
• Temperature and fan status are normal.
• The worker appears Online in PECPool.
• The pool hashrate begins to stabilize.
• Rejected shares are not consistently high.

Your Antminer Is Now Connected

Once the active PECPool server is shown as connected and accepted shares are increasing, your Antminer is successfully submitting mining work to PECPool.

Continue monitoring:

• Worker status
• Current and average hashrate
• Accepted and rejected shares
• Temperature
• Fans
• Hashboards
• Connection stability
• Earnings
• Alerts

For greater reliability, always configure all three official PECPool stratum addresses and assign a unique worker name to every Antminer.
