Connectivity Solutions

Features
Improve Management with an Integrated Campus Network
Virtual deployment of dual switches, extensible architecture and intelligent O&M offers a simple, flexible, and high-performance network for serving all scenarioss on campus.

1G Switch with High-speed 10G Uplink
1G SFP ports downlink for access layer, and 10G SFP+ ports for uplinks or virtual stacking to provide flexible network deployment.


Support 6 Units Stacking to Increase Port Density and Simplify Management
Four 10G ports can be used for stacking via transceivers or DAC/AOC cables.


Dual Redundant Power Supplies and Smart Fans
1+1 Redundant PSUs ensure the continuous normal operation of switch, variable-speed fans with front-to-back airflow for superior cooling, noise and power reduction.

ERPS Enables Failover Protection in Sub-50ms
ERPS (Ethernet Ring Protection Switching) implements loop blocking and link recovery faster than STP on the main device, and can effectively add redundancy and up-time protection to any network.

Block the RPL owner to avoid sending data endlessly in a loop

Unblock RPL owner to ensure non-stop traffic forwarding
QoS (Quality of Service) for Better Traffic Control
Provides different priorities to different applications, users, or data flows to reduce packet loss, latency, and jitter on a network.

Comprehensive Security Policy Protects from Network Threats
With network-level security and stability capabilities like SSH, ACLs, AAA, 802.1X, etc., it defends against network threats for enterprises, campuses, and the financial industry.
