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.

 

 

	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
	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, TCP/UDP port and DSCP)
	The ES-3148 also comes with the intrusion lock feature designed to prevent unauthorized access. In addition, the ES-3148 is capable of providing enterprise-class L2 VPN with VLAN Stacking (Q in Q) to enhance security protection
	L2+ (L2-L4) Access Control List (ACL) allows for better QoS and multimedia
	ZyXEL iStacking Technology allows you to managed multiple switches from one IP
	SSH v1/v2, SSL/TLS for secure management
