Name: 48 10/100/1000BASE-T Ports and 4 1G SFP Ports (non-combo), AC
Brand: Ruijie Networks
SKU: RG-S2952G-E

It gathers densely populated floors into one box and reaches the backbone over fiber.

A managed gigabit switch for access layers that need high port density. Copper ports gather desktop groups, while non-combo SFP ports carry the backbone link. A USB 2.0 port keeps the configuration backup beside the device.

Key features

48ports

High port density

It connects a large user group to the network within a narrow cabinet footprint.

256Gbps

Switching Capacity

At 87 Mpps of packet forwarding it carries floor traffic without congestion.

3MB

Port buffer

It buffers packets during load spikes and reduces loss.

4KVLANs

Network segmentation

It defines 802.1q, private and voice VLANs, separating voice traffic from data.

32AP

Link aggregation

LACP groups ports and adds redundancy on the backbone link.

16KMAC

Address table

It recognizes endpoints simultaneously in a crowded access layer.

DAY-TO-DAY USE

Smart temperature controlIt adjusts fan speed to the environment and signals an alert on fan failure.

On-site backupThe USB port keeps the configuration next to the device and restores it during a swap.

Secure access802.1x, DHCP snooping and IP source guard keep unauthorized devices off the network.

Usage AreaGovernment buildings·Manufacturing, energy and metallurgy plants·Hospitals and libraries·Fair and exhibition centers·Server clusters
