RG-NBS3100-48GT4SFP-P-V2 — 48-Port Gigabit Layer 2 Cloud Managed PoE Switch, 4 x 1G SFP Uplinks
The Ruijie Reyee RG-NBS3100-48GT4SFP-P-V2 is a 48-port Gigabit Layer 2 cloud managed PoE switch with 4 x 1GE SFP ports for uplinks. Its model name marks it as the V2 of the RG-NBS3100-48GT4SFP-P.
What the RG-NBS3100-48GT4SFP-P-V2 is for
This switch suits networks that need many PoE+ ports in one unit, such as banks of IP cameras or access points. Ruijie list IP camera recognition among its features. Each of the 48 RJ45 ports can supply up to 30 W.
The 370 W PoE budget is shared across all ports, so the switch cannot deliver 30 W to all 48 at once. Add up the draw of every device you plan to connect. Ruijie also list a PWM fan optimised for low noise, a PoE watchdog, VLAN, link aggregation and IGMP snooping. Zero-touch provisioning is supported on Ruijie Cloud, and VLANs can be configured in the Ruijie Reyee app.

What you will need
You need Ethernet cable to each powered device and a mains supply. The four uplinks are 1G SFP ports, so fibre uplinks need 1G SFP modules bought separately; a 10G module will not run at 10G in them. Powered devices must be PoE (802.3af) or PoE+ (802.3at); nothing above 30 W per port is supplied. Tell us your device 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-V2 with you before you buy — the PoE budget against your devices, the 1G SFP uplinks and how the V2 differs from the original model — 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.
What is the PoE budget of the RG-NBS3100-48GT4SFP-P-V2?
370 W in total, shared across 48 PoE/PoE+ ports, with a maximum of 30 W on each port. Add up the draw of your devices to confirm they fit.
Does the RG-NBS3100-48GT4SFP-P-V2 have 10G ports?
No. Its 4 SFP ports are 1GE and it has no 10GE SFP+ ports, so it needs 1G SFP modules for fibre uplinks.
How is the RG-NBS3100-48GT4SFP-P-V2 managed?
Ruijie describe it as cloud managed, with zero-touch provisioning on Ruijie Cloud and VLAN configuration in the Ruijie Reyee app. It also lets you monitor switch statistics remotely.
What is different about the V2 of the RG-NBS3100-48GT4SFP-P?
Both Ruijie pages list 48 PoE ports, 4 SFP ports, a 370 W budget and the same Layer 2 features; only the V2 page mentions a PWM fan optimised for low noise. Ask us if you need a detailed comparison with the original model.
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.
Can I collect or see one before buying?
Yes. Our trade counter is at Unit 3, Park View Centre, 243 Dudley Road, Wolverhampton WV2 3JU. Call first so we can confirm the item is there for you.
