GS19020-24HP ALM led red but device works
Options
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?

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
Thanks!
