5.6 Upgrading the Firmware
The Flash program is used to upgrade the firmware on a Liebert LDM unit. It uses the service termi-
nal port to erase the old firmware, copy the new firmware and reboot the unit.
To upgrade the firmware:
1. Make sure the Liebert LDM unit is powered ON.
2. Connect the PC to the Liebert LDM via the external DB9 connection. Refer to 5.2.1 - LDM Setup
Port Connection.
3. If needed, download the latest version of the software (see 5.3 - Downloading the Software).
4. Run the file named Flash x.x.x.exe (where x.x.x is the version number).
5. In the Upgrade Firmware window, click the Select Port button.
6. In the Scan for LDM Units window:
• Select the COM port from the drop-down list—for example, COM1.
• Make sure the Baud Rate is 115200.
• Click the Start Scan button to check for a connection to the unit.
NOTE
Updating the firmware will not erase any configuration settings currently installed. No notice
is given to customers when a new firmware version becomes available. Check Liebert’s Web site
periodically for any available updates (see 5.3 - Downloading the Software).
