GS108LP power supply providing only 52.25v
I purchased a GS108LP back in 2019. I was never able to get it to provide POE power to a WiFi device, and getting no solution from support I just fell back to using an injector.
One symptom was that the switch's Power LED was not lit. It has worked fine as a switch, but has never worked to provide POE.
Today I tested the power supply output and it's only 52.25v, not the full 54v expected, as shown on the label.
Would that cause this type of failure?
Here's a scan of the power supply label.

Hello jhg
And welcome to the NETGEAR Community! 🙂
I'm not sure why you were not provided solution when reaching the Netgear support team. Was your switch a used device when you purchased it? The power of the adapter may not have been providing power enough to the switch. Were you using the original power adapter of the switch?
Have a lovely day,

The GS108LP was new when originally purchased, and the adapter is the one that came with the switch.
When I purchased the switch it was intended to power a new Ubiquiti UAP-AC-LR access point. I was never able to get that working and used the Ubiquiti-provided POE injector instead. Netgear support chalked it up to the fact that the Ubituiti AP was an early board revision that had some known issues with some POE implementations. It has worked fine as a non-POE switch since then.
At that time I didn't notice that the switch's Power LED was not lit.
Is the slightly low voltage likely to cause these symptoms?
- Switch Power LED not lit
- Inability to provide POE
As far as I'm aware 1.75 volts under shouldn't be a problem since POE specs have a wider range than that.
Hi jhg,
Good day!
It seems that you are using the included PA that came with the switch.I am not certain why the power output is below what was advertised. Anyway, this should power up POE/POE+ devices out of the box with 60W POE budget using the PA that came with it. Can you share what type of POE/POE+ devices you tried in the switch?
You may want to look at the product installation guide with POE specs for more information.
Kind regards,
