Network Performance and Connectivity
Engineered for high-density network deployment scenarios, this Ethernet switch can centrally access a large number of Ethernet devices through a single switching platform, simplifying network architecture and improving deployment efficiency. Equipped with a 256 Gbps switching fabric and 130.9 Mpps forwarding capability, it provides sufficient and stable bandwidth support for complex and high-volume enterprise network traffic, ensuring smooth data transmission.
The four shared combination ports bring flexible networking options, with each interface supporting either RJ45 copper cable access or SFP fiber connection, enabling free switching and matching of different transmission media. In addition, a reserved slot on the rear panel supports optional XGM2 module installation, which can expand high-speed uplink capabilities according to actual network construction needs, reserving upgrade space for subsequent network iteration.
The device integrates multiple advanced network management functions, including VLAN partition configuration, load-sharing trunk bundling, port-based Quality of Service queue management and fine-grained access control. These powerful functional features enable the switch to adapt to segmented, hierarchical and refined managed network architectures, meeting the precise management and operational requirements of enterprise-level networks.
DC Power Design and Hardware Structure
The core design feature of this switch is its professional DC power supply architecture. The built-in DC power module supports an input voltage range of -36 VDC to -72 VDC, with a standard nominal input voltage of -48 VDC. This design is highly compatible with the centralized DC power distribution system widely used in telecommunications and professional industrial facilities, ensuring stable operation in dedicated power supply environments and reducing power adaptation costs.
The compact and integrated chassis integrates multiple functional modules and interfaces, including high-density Gigabit Ethernet port area, dual-mode RJ45/SFP combination interfaces, serial console debugging interface, independent dedicated management port, real-time status and diagnostic indicator LEDs, high-speed stacking interfaces, expandable 10 Gigabit expansion slot, professional DC power input terminal and standardized grounding connection terminal.
Adopting a standard 1U rack-mounted chassis design, the device features compact overall dimensions of 17.4 inches in width, 17.0 inches in depth and 1.73 inches in height. It can be perfectly installed in standard industrial and network equipment racks, saving cabinet space and facilitating centralized deployment and unified management of network equipment.
Typical Applications
With its excellent performance, flexible expansion capability and professional DC power adaptation, this managed Ethernet switch is applicable to a wide range of professional network environments, covering:
-
Enterprise core and access layer network infrastructure
-
Data center access network deployment
-
Telecommunications service facilities and central office network systems
-
Industrial Ethernet working environments
-
Server rooms and professional equipment computer rooms
-
High-density campus network scenarios
-
Network convergence and aggregation application scenarios
Its exclusive -48 VDC DC power supply design brings unique application advantages for all scenarios with built-in centralized DC power infrastructure, realizing seamless docking with existing equipment systems.
Installation and Maintenance
The switch needs to be installed in a standard equipment rack or cabinet with good ventilation and heat dissipation conditions, ensuring unobstructed airflow around the chassis to avoid overheating. Before DC power connection, professional technicians must strictly check and confirm the power supply polarity, input voltage range, grounding connection status and matching cable specifications to eliminate potential safety hazards.
In terms of power connection configuration, the official standard configuration adopts 14 AWG power cables and TYCO 206060-1 connectors to ensure stable and safe power input.
For daily routine maintenance, technicians need to regularly inspect the connection status of Ethernet and SFP ports, monitor the operating status of system indicators and fan components, continuously maintain good equipment ventilation conditions, and regularly view and analyze system diagnostic data. Meanwhile, it is necessary to clean the dust around the ventilation openings regularly to prevent dust accumulation from affecting heat dissipation and ensure long-term stable operation of the equipment.
Product Advantages
This enterprise-class managed Ethernet switch integrates high-density Gigabit access ports, flexible SFP fiber expansion capability, enterprise-level high-speed switching performance and professional -48 VDC DC power supply design in a standard rack-mounted chassis. The high-density port design meets the large-scale device access demand of high-capacity networks, while supporting unified and centralized network management, effectively reducing network operation and maintenance costs.
With stable performance, strong compatibility and flexible expandability, the device serves as an ideal choice for enterprise network daily operation maintenance, old system replacement and network infrastructure expansion projects. It can be perfectly compatible with the supporting equipment environment of Extreme Networks, providing reliable and cost-effective equipment support for network upgrading and iteration.
