4.7.1 Using the KVM Firmware Uploader utility
1. Download the latest ServSwitch Freedom unit KVM Firmware Uploader from Black Box Technical Support or from the Black
Box website and install it on a Windows based upgrade computer that will be connected to the ServSwitch Freedom unit. The
files are supplied as a compressed ZIP file. Decompress the ZIP file with an appropriate tool such as WinZip (www.winzip.com)
and copy all contained files to the same folder on the upgrade computer.
2. Remove the power supply plug from the rear panel of the unit.
3. Use the supplied Flash Upgrade Adapter and any CAT5 patch cable to link the serial port of the upgrade computer to the
ServSwitch Freedom OPTIONS port. There is no need to adjust the computer’s serial port settings as the application will do this
automatically.
4. While powering on or when already powered: Press and hold the COMPUTER and MODE buttons (for up to ten seconds) until
the numeric indicator shows ’U’.
5. From the folder created/used in step 1, select the KVMUploader file/icon to run the upgrade utility. The KVM Firmware
Uploader dialog will be displayed:

6. Click the Query Unit button to confirm that communication is possible with the ServSwitch Freedom unit and to establish its
firmware details. If successful, the ‘Unit connected’ field should show the name of the ServSwitch Freedom unit and the cur-
rent firmware will also be listed.
If the application cannot contact the ServSwitch Freedom unit, re-check the connection cable and click the Advanced... button
to check that the correct serial port is being used. Change the serial port within the Advanced... section, if necessary.
