Draco U-Switch
Configuration

7.3.1 Updating the Extender Firmware
The U-Switch can be updated via copy & paste using the Mini-USB service port of the U-Switch. The firmware
type is part of the file name such as the MSD firmware the file extension
.pfw
, e.g.,
HUSWMSD.pfw
.
NOTICE
Possible failures when updating the firmware
In case the HUSWMSD and/or HUSWITCH firmware part of the U-Switch require an update, there may
be dependencies between the new contents of HUSWMSD and/or HUSWITCH firmware files and other
U-Switch firmware files. In this case, installing other firmware files before updating HUSWMSD and/or
HUSWITCH firmware files could lead to failed updates.
To proceed successful firmware updates:
Please check the release notes of the firmware package for dependencies between the U-Switch
firmware files.
If you got information from the manufacturer’s technical support that an update of HUSWMSD and/or
HUSWITCH firmware files of a U-Switch is required, please follow the instructions in this chapter.
By updating the HUSWMSD firmware via copy & paste, the
Config.txt
will be overwritten. If there are
parameters set in the
Config.txt
, they are lost and have to be set again. To avoid resetting the
parameters:
Store the
Config.txt
before updating the HUSWMSD firmware and copy the stored
Config.txt
after updating the HUSWMSD firmware back to the flash drive of the U-Switch.
To achieve a successful firmware update, proceed as follows:
Update all
.pfw
files sequentially.
First update the required HUSWMSD firmware.
Then update the required HUSWITCH firmware.
Then update all other
.pfw
files one by one, file by file if necessary.
Wait between each copy process until the respective copy process has been completed.
Restart the U-Switch after all copy processes of other
.pfw
files have been completed.
If required, the update files can be requested from the manufacturer’s technical support.
Preparation
If the chassis where the U-Switch to be updated is located, contains a 474-SNMP module, we recommend
activating the syslog function of the 474-SNMP module before upgrading the firmware. Please refer to the
user manual of the 474-SNMP module.
We recommend using a central location for firmware files, e.g., by using the management software’s option
menu under Extras > Options > Default Settings > Firmware Directory.
Preserving the Parameters of the Config.txt
To optionally store the
Config.txt
before updating
HUSWMSD.pfw
firmware, if the Multi-Screen Control
has been configured and/or if parameters have been set, proceed as follows:
1. Connect the U-Switch to your computer using a Mini-USB cable.
The flash drive of the U-Switch opens.
2. Copy the
Config.txt
from the flash drive of the connected U-Switch and paste it to a local directory.
