Key Features
Stackable Architecture
Up to 8 units stack via 1 Gbps links creating virtual switch with unified management; simplifies campus wiring closet deployments.
Flexible Uplinks
Dual Gigabit RJ-45 stacking ports plus 2 SFP slots support fiber/copper uplinks to core; auto-failover maintains connectivity.
Advanced L2 Features
4K VLANs, IGMP snooping, QoS (8 queues), port security, RADIUS/SSHv2 authentication; protects converged voice/data traffic.
Enterprise Management
SNMPv1-3, RMON, HTTP, Telnet, Syslog; flow control and auto-MDI/MDI-X simplify deployment across branch offices.
Application Scenarios
Campus Floor Switches
Universities connect 24 workstations per floor; stacking links multiple floors with single IP management address.
Retail Store Connectivity
Chains power POS terminals and surveillance cameras; SFP uplinks connect to central store router reliably.
SMB Office Cabinets
Small businesses consolidate switching for PCs/printers; RPS redundancy ensures uptime during power glitches.
Branch Office Aggregation
Enterprises link departmental switches; IGMP snooping optimizes multicast video distribution efficiently.
