Network switch FUJITSU PLAN EM X557-T2 with 2x10GBASE-T ports (S26361-F3067-L21)

The FUJITSU PLAN EM X557-T2 network switch offers two 10GBASE-T copper ports delivering 10 Gbps connectivity over standard RJ-45 cabling. Engineered for rack and server environments, this compact switch provides low-latency copper links suitable for uplinks, aggregation and direct server connections. Its form factor and interface type make it easy to integrate into existing network stacks where short to medium reach 10GbE over copper is required.

Advantages

The device supplies two high-speed 10GBASE-T ports that allow use of familiar copper cabling and RJ-45 connectors without the need for fiber transceivers, simplifying deployment in environments with existing copper infrastructure. Low latency transmission and straightforward compatibility with common networking equipment reduce integration time. The switch's design focuses on reliable 10 Gbps throughput for critical server and aggregation links in data centers and enterprise networks.

Suitable for

• Server uplinks and direct server-to-switch connections
• Top-of-rack aggregation in small racks or appliances
• Short- to medium-distance 10GbE links over Cat6/Cat6a copper cabling
• Environments that require copper 10G connectivity without fiber optics

Key specifications

• Interface: 2 x 10GBASE-T RJ-45 ports for copper connections
• Speed: 10 Gbps per port
• Cabling: compatible with Cat6/Cat6a (short- to medium-reach 10GbE)
• Typical use: uplink, aggregation, direct server links in rack environments
• Physical: compact form factor designed for integration into server/rack systems

How to use

Install the switch in proximity to servers or the rack position where uplinks are required, ensuring adequate airflow and power availability according to your server chassis or rack appliance guidelines. Connect standard Cat6/Cat6a copper cables to the 10GBASE-T RJ-45 ports on both the switch and the corresponding server or aggregation device. Configure link speed and network settings on connected devices as needed; the switch provides 10 Gbps physical connectivity while higher-level configuration is handled by the network equipment and management software in your environment.

Recommendations

For reliable 10GbE performance, use quality Cat6a cables for longer 10G runs and verify cable terminations and patch panels. Place the switch near power and ventilation sources, and confirm compatibility with your server or chassis interfaces. Monitor link status during initial deployment to ensure stable 10 Gbps connections and address any duplex or negotiation mismatches at the connected endpoints.
