Can Zyxel GS1920-24HP V4.10(AAOC.4) | 09/16/2014 run PoE+ devices?
Welcome to Zyxel community~
GS1920-24HP can support PoE+ (IEEE 802.3at) PD.
Moreover, the firmware 4.10(AAOC.4) you use is kind of old, we highly suggest upgrading to the latest 4.50(AAOC.2).
Thank you for response and advise, I have upgraded my switch to provided firmware.
One more question if possible: After upgrade, and changing password, each time I click any position in "Web configurator" menu, I need to provide password. Is the way to stop it?
FYI, "web configurator" works fine now no issues with credentials popup.
Glad to hear that, btw, you can try clear your browser's cache for the credential request popping issue.
