Description
The Fujitsu LB4M is a high-performance Layer 2/3 managed switch designed for enterprise and data center environments requiring robust networking capabilities. Housed in a compact 1U rackmount chassis, it features 48 Gigabit Ethernet ports and 4 10-Gigabit SFP+ uplink ports, offering ample connectivity for high-density deployments. Its metal construction ensures durability, while front-facing ports and LEDs provide easy access and status visibility. The switch supports advanced features such as VLANs, QoS, link aggregation, and IPv4/IPv6 routing, making it a versatile option for complex network topologies.
Internally, the LB4M is powered by a Broadcom switching ASIC and typically includes a dual-core processor with dedicated memory for management and packet processing tasks. It supports redundant power supplies for improved uptime and hot-swappable fan modules to maintain airflow in demanding environments. With a switching capacity of up to 176 Gbps and a forwarding rate of 130.95 Mpps, it handles high-throughput traffic efficiently. This model is often favored in the secondary market for its reliability, scalability, and compatibility with third-party network management tools.
