Hi, that is what I needed.
The device layout value is set to default in deviceTypes.properties.
EXTR: Device Manager: XOS Stack should be horizontal not vertical view
Verified this has been corrected in a later 6.2 Release.
Thanks for reporting it.
To fix this in 6.2 there is an override in MyDeviceTypes.properties.
You need to add an entry for this device and add devicelayout=45
And the server needs to be restarted.
The FlexView is a better solution for 6.2 if you can wait.
This is the format of the device: adding the last line in bold should change the chassis layout.
