  • Page 95 WS4 Troubleshooting Testing the Power Supply and System Board Voltages If a single ALWAYS voltage is missing, swap the power supply. If the replacement power supply is missing the same voltage, this is likely a short on the system board causing the power supply output to shut down.

    WS4 Troubleshooting POST Errors POST Errors POST errors are summarized in the table below. How the WS4 behaves after a POST error is determined by the boot loader version. If boot loader V2.0.08 or earlier encounters a POST error, the error code sounds once, and the unit powers off.
  • Page 98 WS4 Troubleshooting POST Errors Note 3 The POST cannot detect the Disk On Chip. The device is installed, not installed correctly, not formatted, defective, or a system board/socket problem preventing the POST from accessing the DOC. In addition, there may be instances where a defective or corrupt Disk On Chip prevents the workstation from booting, but a POST error is not reported.
  • Page 99 WS4 Troubleshooting POST Errors Note 6 The POST checks SDRAM by reading and writing 0xAA and 0x55 patterns to each memory location. If the DIMM is not installed however, a POST error does not occur. Instead, the workstation exhibits symptoms similar to that of a bad boot loader chip. See Step 2 in the Operational Troubleshooting section.
