<p>The manual says:</p>

<blockquote>
  <p>The AntMiner S9 can be set up with three mining pools, with decreasing

  <p>The pools with low priority will only be used if all higher priority
  pools are offline.</p>

<p>On older S-series models there used to be a "Pool Balance" setting on the pool screen, below the "pool 1", "pool 2", "pool 3" in your screenshot. From the manual for the old S3:</p>

<blockquote>
  <p>AntMiner can set up three mine pools, the priority decreases from
  first pool (pool 1) to third pool (pool 3). There are three Pool
  Balance option:</p>
  
  <p>Failover: Automatic backup when Miner faults;
  ‘Failover’ is by default. The low priority pool will start to work,
  only when the high priority pool encounter fault.</p>
  
  <p>Balance: Change
  multipool strategy from failover to even share balance.</p>
  
  <p>Load Balance:
  Change multipool strategy from failover to quota based balance.</p>

I have purchased and got running Antminer S9. While setting it up I notices that I can specify three pool connections

I was unable to find the purpose for this.

Are those backup options just in case one or two pool connections are down or should I could actually mine for three pools at the same time?
