Kostengünstiger 24 Port Managed Gigabit Layer 2 Switch + 4x SFP miniGBIC Slot Without cooling fan for desktop and 19 rack installation Highlights: 24 Port Gigabit non-blocking switch architecture Supports NWay protocol for speed (10/100 / 1000Mbps) and duplex mode (half / full ) auto-detection Supports back-pressure (half duplex), flow control (IEEE 802.3x and IEEE 802.3az Energy Efficient Ethernet VLAN "64 Static / Port-Based / Tagged Based link aggregation (IEEE 802.3ad LACP & Static trunk) IGMP Snooping (v1 / v2 / v3) QoS (Port Based, flow, 802.1p, IP TOS, IP DSCP) Storm Control (broadcast, multicast, unicast) Total Lüfterlos, no annoying noises more ... (19 -inch angle) or wall / table mounting possible The new Lieske Elektronik ALL-SG8428M switch provides an ideal basis for small and medium workgroups with high network and data traffic is and allows rapid data transmission in Netzwerk.Mit total 16 Gigabit abwärtskompatiblen ports are the connected computer and Serverzuverlässig and powerful together verbunden.Durch the lüfterlose design is the ALL-SG8428M also ideal in Büroumgebung usable because any troubling noises are generated. The switch is smart manageable and thus supports all nötigen standards such as QoS, VLAN, storm control and IGMP Snooping. This provides for highest performance and security in their network.The robust Housing metal is both for installation in 19 € œ cabinet, suitable for wall mounting.
