The System Update Utility is a feature built into the System Administrator that lets you update your DSX system software. This utility is an alternative to using a CompactFlash card to update system software.

Before using the System Update Utility:

1. Make sure you have the following installed:
• The latest version of the DSX System Administrator.
• DSX System Software 01.01.27 or higher.
2. Download the DSX System Software file to which you want to update.
   • To get the latest System software, go to the DSX Download Center at left and click System Software.
• Download the system software zip file to a convenient folder on your PC hard disk.
• Do not unzip the software file.
3. Connect your PC to the telephone system (USB only).

6. Click Start.
• If the admin program is not already connected, you will be prompted for your password.
7. After you click Start, the three phases of the update process automatically execute.
   • Phase 1: System Reset
     The DSX resets and restarts in the update mode. The system is inoperable while in the update mode.
   • Phase 2: File Transfer (Upload)
     The System Update Utility transfers (uploads) the zip file from your PC to the system.
   • Phase 3: System Update
     The system updates its software. After the update completes, the system resets and operates normally with the new software version.
8. After the system software update completes (about 8 minutes), the T1/PRI PCB may automatically load updated firmware (which takes an additional 6 minutes). The LEDs on the T1/PRI PCB alternately flash during the firmware upload.
