### Antminer S9 Maintenance Guide - Detailed Repair Instructions
#### Overview
The following guide provides detailed steps for repairing the Antminer S9 hashboard, focusing on identifying faulty chips using voltage readings from various test points. The guide will also explain how to use a multimeter to measure specific voltages to pinpoint the malfunctioning chip.
#### Required Tools
- Multimeter (preferably FLUKE 15B+ or similar for accurate readings)
#### Voltage Domains and Chip Layout
The S9 hashboard is divided into 21 voltage domains, each domain comprising three chips. The chip layout is as follows:
- **Top Rows (1.9 Version)**: RST, BO, RI (RX), CO (TX), CLK
- **Bottom Rows (4.2 Version)**: CLK, CO (TX), RI (RX), BO, RST
#### Key Test Points and Normal Voltage Values
- **1st and 6th Rows:**
- **CLK**: 0.4-0.9V
- **CO**: 1.6-1.8V
- **RI**: 2.1-2.2V
- **BO**: 0V
- **RST**: 1.6-1.8V
- **2nd to 5th Rows:**
- **CLK**: 0.9V
- **CO**: 1.6-1.8V
- **RI**: 1.6-1.8V
- **BO**: 0V
- **RST**: 1.6-1.8V
#### Test Methodology
1. **Initial Setup:**
- Connect the 12V power supply to the hashboard.
- Ensure the IO wire is not plugged in initially.
2. **Voltage Measurement:**
- With the 12V power supply connected, use the multimeter to measure the DC-DC output and booster voltage output:
- **DC-DC Output**: Approximately 9V
- **Booster Voltage Output**: Approximately 14V
3. **Check Test Points Without IO Wire:**
- **CLK**: 0.9V
- **RI**: 1.8V
- Other points should be 0V.
4. **Check Test Points With IO Wire:**
- Plug in the IO wire and press the test key on the tool. The expected voltages are:
- **CLK**: >0.9V
- **CO**: 1.6-1.8V (initially 1.5V when WORK signal is sent)
- **RI**: 1.6-1.8V
- **BO**: 0V (0.1-0.3V during computing)
- **RST**: 1.8V
5. **Signal Flow Check:**
- **CLK** signal flows from Pin 24 in and Pin 6 out, passing through a 100NF capacitor to the next chip.
- **TX** signal flows from Pin 26 or 27 in, Pin 5 out.
- **RX** signal returns from Pin 4, Pin 28 out.
- **BO** signal flows from Pin 29 or 30 in, Pin 2 out.
- **RST** signal flows from Pin 31 or 32 in, Pin 1 out.
#### Troubleshooting Faulty Chips
To identify a malfunctioning chip, measure the RI (RX) voltage from the last chip to the first chip:
1. **RI Voltage Check:**
- Begin at the last chip in the signal chain.
- Measure the RI voltage; it should be 1.6-1.8V.
- Move to the preceding chip if the voltage is within range.
- Identify the faulty chip when you find an RI voltage significantly lower than the expected range.
2. **CORE Voltage Check:**
- **CORE** voltage should be 0.4V. An anomaly here indicates a potential short circuit in the chip's voltage domain.
3. **LDO Voltage Check:**
- **LDO-1.8V**: Ensure 1.8V output from LDO-1.8O and input from LDO-1.8I.
- **PLL-0.8V**: Should read 0.8V; anomalies here indicate issues with PLL power supply or LDO-1.8V in the voltage domain.
#### Additional Notes
- Ensure consistent use of a reliable multimeter to avoid discrepancies due to tool variance.
- Follow the signal flow and voltage checks meticulously to accurately identify the faulty chip.
By following this detailed guide, technicians can systematically diagnose and repair issues with the Antminer S9 hashboard, ensuring optimal performance and minimizing downtime.
