Problem

The file system is broken on the PBX or the PBX doesn't switch on.

Solution

Perform a reflashing procedure as described below.

Important: this procedure can be applied only to PBXs with Atom and Celeron Processors (in production since 2015) having a MSATA SSD, see the picture below to know whether this procedure can be performed on your PBX

  • Eject a hard disk drive (HDD) from your PBX system

    Note: See the picture below to understand what the HDD looks like.

Important: perform this procedure only if HDD looks like on the picture below!

For example, you can use ZTC Enclosure Adapter: https://www.amazon.com/ZTC-Enclosure-Adapter-Support-ZTC-EN00-S/dp/B00RNECU36

  1. Connect HDD to your PC using USB mSATA adapter
  2. Download the disk image: WMS_5.04_x64_20220706.img / WMS_6.02_x64_20230519.img
  3. Use disk dump utility to burn the image to the HDD of your PBX

  4. The command syntax depends on your OS:

    – dd if=wms.img of=<dev_msata> //pat
  5. Install the HDD back to your PBX and boot the system
