Can someone please tell me which Miner Settings are working ... I'm mining since 1 year with cgminer, sgminer and ccminer but I don't have a clue what's Quota

These are my current not working settings:

{
  "pools": [
    {
      "quota": "stratum+tcp://stratum.nicehash.com:3333",
      "user": "my-BTC-walletaddress",
      "pass": "x"
    }
  ]
}

HW Status says only ASIC Slot 5 and 6 are working but two other cubes should be recognized. I have 2 PSUs with 1300 watt each, both running, all cube fans running.

I've connected all 4 cubes the same way to the board, red wire on the right, if you look at the board.

One red LED (below PP10) is on, at the top board (the one with the LAN connector).

Any ideas?

How do I safely shut down the Titan with 4 cubes?
