    Hi @murdok,

    Welcome to the Zyxel Community!

    The latest firmware version available for your GS1900-24HP (Rev A1) switch is V2.70(AAHM.3)C0. The "C0" in the firmware designation refers to the official patch version and is not specific to a hardware revision. Therefore, you can install firmware versions labeled "C0" on your Rev A1 device.

    You can download this firmware via this link.

    Since the GS1900-24HP has reached EoL status, we recommend exploring the GS1900-24HPv2 or our current switch offerings here: Switch | Zyxel Networks for optimal performance and support.

    Hi @murdok,

    We applied the firmware version and rebooted the device. Afterward, the GUI displayed correctly as shown in the image below.
