Ruijie RG-NBS3100-48GT4SFP-P-V2: 48-Port Managed Gigabit PoE+ Switch
The Ruijie RG-NBS3100-48GT4SFP-P-V2 is a managed Ethernet switch built for networks that need many wired connections and reliable power for connected devices in one unit. Its 48 gigabit ports and SFP uplink slots make it a practical choice for offices, schools, small campuses and commercial sites where a central switch has to serve a large number of endpoints.
Key features
- 48 managed gigabit ports for wired connections to workstations, servers and network devices
- Power over Ethernet (PoE+) on the downstream ports, with a total power budget of 370W
- SFP slots for uplinks, allowing connection to a core switch or backbone using compatible modules
- Managed operation, so settings can be adjusted to match the network design
- UL mark as stated in the product description
Power over Ethernet
PoE allows the switch to deliver electrical power along with data over the same network cable. This removes the need for separate power outlets near devices such as wireless access points, IP cameras, IP telephones and access control units. The 370W total budget is shared across all powered ports, so the number of devices that can be powered at once depends on how much power each one draws. Plan the load before installation and check the per-port limits in the supplier documentation.
Management and network control
As a managed switch, the unit gives administrators control over how the network behaves. Ports can be configured, monitored and organised to suit the layout of the site. This is useful when different departments or device groups need to be separated, or when traffic needs to be managed to keep important services responsive. Managed switches also make troubleshooting easier because the status of each port can be checked.
Connectivity and uplinks
The four SFP slots are suitable for uplinks, which connect this switch to the rest of the network over longer distances or higher-capacity links. Choose SFP modules that match the fibre or copper type used in your building and that are compatible with Ruijie equipment. Using SFP uplinks keeps the access layer flexible when the network grows.
Typical uses
- Powering and connecting wireless access points across an office or campus
- Supplying PoE to IP cameras and video surveillance systems
- Connecting IP telephones and desk devices in a single cabinet
- Serving as an access switch in a school, hotel or commercial building
- Linking a floor or building to the core network through SFP uplinks
Installation considerations
Install the switch in a suitable network cabinet or rack with adequate ventilation, because a 48-port unit with PoE produces heat under load. Plan the power supply and cable routing before mounting. Label ports and keep a record of the configuration so that changes can be made safely later. Confirm the mounting, power input and environmental details in the supplier documentation before installation.
Who it is for
This switch is intended for IT staff, network installers and businesses that need a dependable central switch for a large number of wired and PoE devices. It is a good fit when a single high-density unit is preferred over several smaller switches, and when managed features and uplink options are required.
