Upgraded backup firmware listed as Unknown

zyxelplz

gs1900 24E

Active firmware is V2.40(AAHK.0) | 11/14/2017

I applied runtime-GS1900-24Ev2-V2.90(AAHK.1).bix to the backup slot but it shows "Unknown" under Information.

I'm concerned if I try to activate, its going to brick the device (i.e. wont boot and let me revert)

Please advise.

Hi @zyxelplz

This is just a display error on older firmware, it won't occur any issue. You can activate the latest firmware.
