" To configure fail-over pools the options --pool --user and --pass can be passed multiple times to the miner. They will be processed in order, so the first occurrence belongs to the primary connection, the second to the first fail-over and so on. When the miner looses connection to the primary pool too often (5 times in a short period of time), it will try to connect with the second set of credentials. "
