GS19020-24HP ALM led red but device works

Elysium

Hello
On my switch, the red ALM led is lit on 2 ports but the peripherals (a Phillips TV and a Sonos connect) work perfectly.
What can I check to correct this problem? I tried with another cable, the led stays on.

Do you have another idea?

Device type : GS1920-24HP

Firmware : V4.50(AAOC.2) | 02/27/2018

Thank you

Hi @Elysium

The ALM red normally relates to switch's hardware anomaly (such as fan speed, MAC/PHY temperature), you can check in status page.




You may also check the syslog to see if any error/warning log.

BTW, this forum is for home devices, for our business model devices such as GS1920 series, you may seek our biz forum. https://businessforum.zyxel.com/categories/switch-discussions
