Grandstream
PSU-GXW41XXPSU for GXW4104, GXW4108
The genuine Grandstream power supply for the GXW4104 and GXW4108 FXO gateways.
This adapter powers the box that keeps your analogue lines connected. The GXW410x sits between the phone system and the exchange lines — when its power supply fails, the analogue lines stop reaching the PBX and inbound calls die with them. That failure usually surfaces years into service, long after the original adapter's box was thrown away. This is the part that fixes it the same day rather than after a support case about “the lines being down”.
Use the correct adapter. Voltage and polarity vary across the Grandstream range, and a generic supply of roughly the right size can damage the device.

Frequently asked questions
How do I know the adapter has failed and not the gateway?
No lights at all usually means power; lights but no registration means something else. Swapping in a known-good adapter is the two-minute test — which is the argument for keeping one in the cabinet.
Can I use any adapter of the same size?
Better not to. Voltage and polarity differ across the range and the wrong supply can damage the device — and this one has all your analogue lines behind it.
