SG110 POE

kasper · ‎11-27-2021

Hi,

I have a SG110 switch. Suddenly after a power down the switch is not supplying any POE consumers. Is there anything to try to make it work again? The link LED is lit but not the POE and there is no power at the consumer.

Thanks.

- Check the logs and or also , when a device expects POE

Thank you, but are there any logs when the switch is unmanaged?

- Ok, indeed none, consider remarks from Philip too in this thread :

Hi,

There is not much scope for troubleshooting on the unmanageable switch like SG110. I hope the mentioned PoE consumers are 802.3af supported, SG110 switch support that standard.

To get support on that hardware you contact TAC via the link https://www.cisco.com/c/en/us/support/web/tsd-cisco-small-business-support-center-contacts.html

Hi Sujoy,

Thanks. No, I was affraid of that. It has worked with PoE on the same consumers for 2-3 years so it should be fine.

Hi Kasper,

Thanks for your reply. If that PoE setup was working fine for so long then it might be a hardware failure (SG110 Switch) provided those PoE consumers are working fine on other PoE Switch.
