PARTRPS-300W-B
The Grandstream RPS-300W-B is the 54V 5.6A power supply for the GWN7813P PoE aggregation switch. Unlike an ordinary switch supply, this one carries the PoE budget as well as the switch's own draw — which is why it is a 300W unit rather than a 60W brick.
If a GWN7813P is powering access points, cameras or phones, this supply is the single point everything downstream depends on. That makes it the one spare worth having on the shelf: when it fails, the switch and every powered device hanging off it go down together, and a replacement ordered on the day is a replacement that arrives too late.
Ideal for
- Replacing a failed or missing supply on a GWN7813P
- Shelf spares for a PoE aggregation switch carrying access points or cameras
- Comms rooms where a swap needs to happen in minutes
- MSPs and installers holding critical spares for managed sites
- Sites that will not run a PoE switch on a generic supply
Key features
- Genuine Grandstream supply — correct voltage, polarity and connector for the switch
- 54V DC at 5.6A, 300W — sized to carry the switch and its PoE budget
- PoE-rated — 54V is what 802.3af/at/bt devices are powered from
- Direct replacement — no configuration, no downtime beyond the swap
- Sold individually — order per switch; project quantities on request
Works with
- Grandstream GWN switches — including the GWN7813P
- RPS-60W-B 12V supply — the non-PoE version, for the GWN7813, GWN7831 and GWN7832
- Grandstream GWN access points — typically what this switch is powering
- All Grandstream networking
- All PSUs and accessories
Frequently asked questions
Why is this so much larger than the 60W supply?
Because it powers the connected devices too. On a non-PoE switch the supply only runs the switch; on the GWN7813P it also has to deliver the PoE budget to everything plugged into it.
Can I use the 12V RPS-60W-B instead?
No. PoE devices are powered at 54V and the GWN7813P is built around that. The 12V supply is for the non-PoE models.
Will a generic 54V adapter do?
We would not advise it. Connector, polarity and sustained current rating all have to match, and an under-rated supply on a PoE switch shows up as devices dropping off under load — one of the hardest faults to trace on a network.
Does the switch need to be powered down to swap it?
Yes — and so does everything it powers. Treat it as a planned outage and warn the site before you start.
Should I keep a spare?
If the switch carries your access points or cameras, yes. This is the component whose failure takes the most with it.
