Zyxel ES3148 48-port 10/100 L2 Managed Switch
ZyXEL ES-3148 is a high-density L2+ managed switch with 48 10/100Mbps RJ-45 ports, two GbE copper ports and two dual-personality SFP/copper GbE interface. Coupled with the advanced ASIC hardware and switching capacity of 17Gbps, the ES-3148 is an ideal platform to power premium triple-play applications. What makes the ES-3148 unique is its robust and highly available system design. The support of 802.3ad Link aggregation reduces network downtime by providing more packet paths and bandwidth aggregation to critical paths. In case a link is down, IEEE 802.1w RSTP allows the ES-3148 to quickly recover from failed links and send packets through a backup link. The 4G uplink not only gives superb transmission bandwidth, but also allows you to set up Gigabit aggregation. In addition, BPS is
also available for feeding in extra DC back-up power to prepare for any unexpected power failure. All these great features and more in the ES-3148 give you the network performance you need with minimum downtime. In todays changing networking and business environment, one of the keys to success is in how corporations harness new applications (such as VoIP and video conferencing) for work efficiency. To take advantage of these applications, the ability to manage traffic is extremely important to fully utilize your network bandwidth. The ES-3148 is equipped with L2+ multi-layer ACL (L2~L4) for QoS, 8 hardware priority queues, DSCP and WFQ scheduling algorithm. These bandwidth guaranteeing and priority optimizing features maximize bandwidth usage and provide premium quality network
service. Furthermore, to optimize IP Multicasting applications, IGMP snooping also get supported. For flexible bandwidth control, the ES-3148 allows you to limit bandwidth usage to the granularity of 64Kbps. The multi-layer ACL (L2~L4) protection on the ES-3148 shield against potential network threats. You can create security settings by setting (L2 ~L4) ACL parameters (such as MAC, VLAN, IP, Protocol type,
