1. Quick Troubleshooting Checklist
Before contacting the support team it may be helpful to attempt to resolve some common
issues by first following this list of solutions. However, please do not hesitate to contact
the support team if these solutions do not resolve your error. Please follow all safety
precautions before attempting what is described here.
1. Electronics of all kinds can encounter unexplained errors from time to time,
it usually helps to completely disconnect the power, wait a few seconds, then
reconnect the power again. If the problem persists after a power cycle, please
follow these next steps.
2. If the miner has been restarting with no warning then it may be too hot, please turn
off the miner, disconnect any cables, then leave the miner to cool down for about
an hour or as long as needed, after which please reconnect the miner and turn it on
again.
3. Check that the power cable is firmly connected and is switched on at both
the wall socket and on the miner.
4. Check that the fans on the miner are spinning, if they are not this indicates that the
miner has encountered an error. Please contact the support team.
5. Check that the green light, found on the control panel, is illuminated; this light will
flash at regular intervals. If the red light is illuminated or none of the lights are
illuminated this indicates that the miner has encountered an error. Please contact
the support team.
6. Check that the Ethernet port of the miner is connected to your network and that
it can access the internet. The IP address of the miner can be found on the DHCP
server or your router's homepage.
7. If you can’t login to the miners web interface please make sure you’re entering the
username and password correctly. Note: the login is case sensitive and
the default login is: admin.
8. Check that the mining pool addresses are correct. The mining pool address should
be in the format of: stratum+tcp://eca.ss.greatpool.ca:1800 other
●
●●●
mining pools may have a similar address but the port number (ex. 1800) may differ.
stratum+tcp://[pool address]:[port number]
9. Check that the worker name is correct. The worker name should be in the format
of: MinervaLab.default1 where usually ‘MinervaLab’ is your account name,
there is a full stop after the account name, and then followed by ‘default1’. This
is usually the name of your miner/worker which is visible in the pool dashboard.
[account name].[worker name]
10.Check the miner is connected to the pool. This can be done by viewing the pools
dashboard, or by looking on the miners web interface and seeing shares being
accepted and the network status reported in milliseconds (ms).
If your encountered problem persists after a power cycle and none of the above solutions
describing your problem in full detail.

2.3.3 How do I Configure my Mining Pool?
Figure 7. Accessing the Pools Management Page on the Web Interface
1. Click on Configuration -> Pools on the left side menu of the interface, shown
in the image above:
2. Click the Add Pool button and input the mining URL, worker number and password
of the mining pool in turn. After the input is completed, click
the Confirm button, and the miner will load the new mining pool configuration
automatically and restart the mining program.
3. The mining pool address entered in the box titled URL should be in the format of:
stratum+tcp://eca.ss.greatpool.ca:1800 other mining pools may have a
similar address but the port number (ex. 1800) may differ. Generic format:
stratum+tcp://[pool address]:[port number]
4. The worker name entered in the box titled Worker should be in the format of:
MinervaLab.default1 where usually ‘MinervaLab’ is your account name, there
is a full stop after the account name, and then followed by ‘default1’. This
is usually the name of your miner/worker which is visible in the pool dashboard.
Generic format: [account name].[worker name]
5. To remove pools, click the delete button in the upper right corner of the label

machine will automatically load the new mining pool configuration and restart the
mining program.
Caution: The mining device will choose one of the mining pools to mine. The last
running mining pool cannot be deleted.
2.3.4 How do I Verify I am Connected to the Mining Pool?
This can be done by viewing your chosen mining pools dashboard, or by looking on the
miners web interface.
The web interface will look like figure 8 (below), please check that the current pool details
are set to your chosen pool address and worker name. Then if the web interface is
reporting a hashrate greater than zero, shares being accepted, and the network status
reported in milliseconds (ms), then you are successfully mining to your chosen mining
pool.
It is quite common for the mining pools dashboard to take some time before it updates,
this could be up to an hour of mining before the mining pools dashboard shows that your
miner is connected and hashing. This of course is dependent on your chosen mining pool,
so your experience may vary.
