Layer 2 cloud managed switch with 48 Gigabit PoE/PoE+ ports and 4 Gigabit SFP uplink slots. The 370 W PoE budget is shared across all 48 ports, with up to 30 W on any one port, so add up your devices' draw first.
RG-NBS3100-48GT4SFP-P — 52-Port Gigabit Layer 2 Cloud Managed PoE Switch, 4 x SFP Uplinks
The Ruijie Reyee RG-NBS3100-48GT4SFP-P is a 52-port Gigabit Layer 2 cloud managed PoE switch, made up of 48 RJ45 ports that can each supply PoE/PoE+ and 4 SFP uplink slots. Ruijie's page points to CCTV networks as a use and lists IP camera recognition.
What the RG-NBS3100-48GT4SFP-P is for
Ruijie position this switch for CCTV networks and list IP camera recognition among its features. With 48 PoE/PoE+ ports it can power a large group of IP cameras or access points from one unit, with up to 30 W available on any single port.
The PoE budget is 370 W in total, not 30 W on every port, so it will not run all 48 ports at full PoE+ draw. Add up the real draw of every powered device and keep the total inside the budget. Ruijie also list a PoE watchdog, VLAN, link aggregation and IGMP snooping. It is cloud managed, with zero-touch provisioning to the cloud, remote monitoring of switch statistics and VLAN setup in the Ruijie Cloud app.

What you will need
You need Ethernet cable to each powered device and a mains supply; a power cord is listed in the box. The four SFP uplink slots are 1G only, so an uplink over fibre needs 1G SFP modules bought separately. Powered devices must be PoE (802.3af) or PoE+ (802.3at); the ports do not supply more than 30 W each. Tell us your camera or access point models and we will check the total against the 370 W budget.
Buying from Zenith Security Co.
We are a supplier, not an installer. We will go through the RG-NBS3100-48GT4SFP-P with you before you buy — the PoE budget against your cameras or access points, the SFP uplinks and what the 30 W per-port limit means in practice — and depending on your requirements and your area we can recommend a qualified trade installer. We have been operating since 2012 and you can visit our trade counter in Wolverhampton.
How much PoE power does the RG-NBS3100-48GT4SFP-P provide?
It has a 370 W PoE budget shared across its 48 PoE/PoE+ ports, with up to 30 W on any one port. It does not have PoE++ (802.3bt) ports, so devices needing more than 30 W per port need another power source.
Are the SFP ports on the RG-NBS3100-48GT4SFP-P 10G?
No. It has 4 Gigabit SFP ports and no 10G SFP+ ports, so it takes 1G SFP modules only. They are separate from the 48 RJ45 ports rather than shared combo ports.
Is the RG-NBS3100-48GT4SFP-P cloud managed?
Ruijie describe it as a cloud managed switch. Their page lists zero-touch provisioning to the cloud, remote monitoring of switch statistics and VLAN setup in the Ruijie Cloud app.
Can the RG-NBS3100-48GT4SFP-P be used with IP cameras?
Its PoE/PoE+ ports can power IP cameras within the 370 W budget, and Ruijie list IP camera recognition as a feature aimed at CCTV networks. Check the total camera draw against the budget before ordering.
How quickly can I get it?
Delivery is within 1–3 working days to England, Scotland and Wales. We do not ship to Northern Ireland.
