DAN-GS1424B

20 GbE + 4 GbE Dual-Media Web-Smart Switch (max. 24 ports)

FEATURES: 20 (10/100/100Mbps) Gigabit Ethernet (TP) switching ports are compliant with IEEE 802.3, 802.3u, 802.3z and 802.3ab. 4 Gigabit TP/SFP fiber are dual media ports with auto detected function. Non-blocking store-and-forward shared-memory Web-Smart switch. Supports auto-negotiation for configuring speed, duplex mode Supports 802.3x flow control for full-duplex ports Supports collision-based and carrier-based backpressure for half-duplex ports Any ports can be in disable mode, force mode or auto-polling mode. Supports Head of Line (HOL) blocking prevention. Supports broadcast storm filtering Web-based management provides the ability to completely manage the switch from any web browser Supports Port-based VLAN and Tag-based (IEEE 802.1Q) VLAN. Auto-aging with programmable inter-age time. Supports 802.1p Class of Service with 2-level priority queuing. Supports port trunking with flexible load distribution and failover function. Supports port sniffer function. Programmable maximum Ethernet frame length (jumbo frame). Efficient self-learning and address recognition mechanism enables for warding rate at wire speed.

MANAGEMENT SUPPORT:
