The S5500-48T6S is a next-generation stackable access switch ideal for enterprise branches, campus networks, and SMBs. Powered by a Realtek chipset, it delivers 216 Gbps switching capacity and 162 Mpps forwarding performance. With 48 Gigabit RJ45 downlink ports and 6x 1/10G SFP+ uplink ports, it supports up to 8-unit virtual stacking for seamless interconnection and centralised management.
Designed for high availability and simplified operations, it features redundant hot-swappable AC power supplies and variable-speed fans to enhance reliability. Multiple management options—via Web, CLI, SNMP, and SSH—enable flexible O&M, improved visibility, and stronger network security. These capabilities make it a scalable and cost-effective solution for access-layer deployments.

Hot-swappable redundant power supplies allow for zero-downtime replacement, delivering continuous uptime and enhanced system reliability. Dual variable-speed fans with left-to-right airflow dynamically adjust speed based on load for efficient cooling and reduced power consumption.
Each switch port supports 8 QoS queues, enabling efficient traffic prioritisation across applications, users, and data flows. This reduces packet loss, latency, and jitter, ensuring consistent network performance.
Voice VLAN makes VoIP do not have to contend with all the broadcasts and other traffic from the data VLAN, ensuring it is transmitted preferentially, reducing packet loss and latency.
With network-level security and stability capabilities like SSH, ACL, AAA, etc., it defends against network threats for enterprises, campuses, and the financial industry.
