Once you've setup your Antminer you are generally home free. However, you should take some time to check on it to ensure that it is running properly.
Hardware Errors and Hardware Error Rate
On the "Miner Status" section of the miner dashboard you can see in the bottom section each hashboard and the far right of that section will show the chips on each board with 0s and Xs. 0s mean the chip is working ok. Xs mean there is some kind of error. Usually a reboot will fix an excessive amount of errors.
