Hardware Specifications

Frequently Asked Questions

How many PoE devices can I connect to the RG-NBS3100-48GT4SFP-P-V2?

The switch has 48x PoE+ ports with a total budget of 370W. For typical IP cameras drawing 10-15W, you can power a large number of ports simultaneously within the budget. At the maximum 30W per port (PoE+), up to 12 ports can run at full load concurrently within the 370W budget.

How does this switch compare to the 24-port model?

The RG-NBS3100-48GT4SFP-P-V2 doubles the port count to 48x PoE+ ports and increases switching capacity to 104 Gbps, making it suited for large floors, campuses, or high-density camera deployments. The 24-port model is better suited for medium-sized installations.

Can I manage this switch remotely?

Yes. The switch supports lifetime free cloud management via Ruijie Cloud, allowing you to monitor port statistics, configure VLANs, manage PoE, and perform firmware updates from anywhere. The Ruijie Reyee mobile app is also supported for on-the-go management.

Does it support IP camera recognition?

Yes. The switch includes built-in IP camera and NVR recognition for easy identification and management of CCTV devices. PoE watchdog enables automatic camera recovery without requiring an on-site visit.

What SFP modules are compatible with the uplink ports?

The 4x SFP uplink ports support standard 1GE SFP modules. Ruijie-compatible options include the MINI-GBIC-SX-MM850 (multimode, 550m) and MINI-GBIC-LX-SM1310 (single-mode, 10KM).

Is the fan noisy?

The switch uses PWM fan control to dynamically adjust fan speed based on temperature, optimising for low-noise operation during normal conditions.

What warranty does this switch come with?

The RG-NBS3100-48GT4SFP-P-V2 is backed by a 5-year Ruijie Reyee manufacturer warranty.
