Available in Two Models: Single Internal AC Power Unit or Dual Power Input (One AC One DC Power Unit)OverviewINTRODUCTIONThe DSGio CMS-428XGF managed switch is engineered for medium to large-scale network deployments, delivering a high-bandwidth, non-blocking switching fabric that enables low-latency, high-speed data transmission. It features multi-rate SFP uplinks to support scalable network expansion and offers link aggregation to maximize throughput and redundancy. With IEEE-compliant standards, the switch ensures reliable and continuous operation of connected IP devices. Comprehensive Layer 2 management capabilities—including VLAN, QoS, and advanced security features—enhance network segmentation, traffic prioritization, and access control. Housed in a 19-inch rack-mountable chassis, the switch integrates seamlessly into enterprise and data center environments.SPECIFICATIONSInterface10M/100M/1000Mbps RJ45 Port4100M/1Gbps SFP Slot241G/2.5G/10Gbps SFP Slot4RJ45 Console Port for CLI Management1System PerformancePacket Buffer32MbNAND Flash Memory2GbNOR Flash Memory256MbSDRAM Memory (DDR3)4GbMAC Address Table Size32KJumbo Frame10KSwitching Capacity136GbpsForwarding Rate (64-byte)101.184MppsL2 FeaturesAuto-Negotiation●Auto MDI/MDI-X●Flow Control (Duplex)802.3x (Full)●Back-Pressure (Half)●Spanning TreeIEEE 802.1D (STP)●IEEE 802.1w (RSTP)●IEEE 802.1s (MSTP)●VLANVLAN Group4096Tagged Based●Port-Based●Q-in-Q●Voice VLANVoice VLAN with OUIMAC-based / Protocol-based / IP Subnet-based VLAN●Link AggregationIEEE 802.3ad with LACP●Static Trunk●Max.
