  • Page 2 S17 Maintenance Guide III. Signal Transmission Circuit 1. Signal transmission channel: signal CLK-RST-BO-CO transmits from No. 1, No. 2 … to No. 48 chip, while RI signal returns from No. 48 to No. 1 chip. See below fig. 2. The identification and sequence of signal test points (the hashboard has 48 chips, 12 voltage domains in total), see below fig.

  • Page 4 S17 Maintenance Guide RX and RO Conversion Schematic Diagram RX and CI Signal and Chip Transfer Schematic Diagram IV. Power Circuit 1. The power supply voltage of each board: (the voltage output of S17 board test is 18.5V). There are 12 voltage domains in total and the voltage of each two voltage domains is 1.55v.
  • Page 5 S17 Maintenance Guide V. Case Analysis of Maintenance (Troubleshooting Examples of Single Board Test) 5.1 Single board test asic=0 Malfunction analysis: 1. Whether the ribbon cable of hashboard tester is connected well with hashboard. 2. If yes, S17 hashboard J6-J7 should have 18.5V voltage during the tester test. 3.
  • Page 6 S17 Maintenance Guide 3.2． If power supply is normal and voltage domains also have voltages, detect the RI signal of chip to see whether RI signal has 1.8V voltage. Detect RI signal from the test point of the last chip. If the last chip has, detect No. 20 chip to see whether it has RI-1.8V, and so forth, until find the chip that has no RI output voltage.
  • Page 7 S17 Maintenance Guide 0.8V Power Supply Schematic Diagram If 0.8V power supply circuit does not have 0.8V output, check if the power supply of 0.8V LDO has about 3.2V power supply voltage. If yes, check whether LDO is in a condition of pseudo soldering/short circuit. If it has 0.8V output, check the resistance to ground of this chip.
