What This Product Does

Designed for small and medium business requirements, PrimusCable.com ES4-4278-52R integrates basic layer 2 management features, such as 802.1Q VLAN, 802.1P QoS, ACL (Access Control List) features. It provides high performance with 48 10/100Mbps ports 2 10/100/1000Mbps ports to deliver maximum throughput for your business networks. Moreover, ES4-4278-52R also comes equipped with 2 Gigabit SFP slot, giving you greater network flexibility. Finally, the PrimusCable.com L2 managed switch ES4-4278-52R equipped advanced security and management features such as 802.1x port authentication, Storm Control, Port Security, Quality of Service (QoS) , STP/RSTP/MSTP and IGMP Snooping to provide enhanced traffic management capabilities and reliability. Moreover, the easy-to-use web management interfaces, along with CLI, SNMP and RMON, mean faster setup and configuration with less downtime.

Secure Your Network Application

The ES4-4278-52R switch supports 802.1x authentication, which is used in conjunction with a RADIUS to require some authentication information before access to the network is allowed. In addition，Port Security, Storm Control support can protect against broadcast/multicast storms and ARP attacks, etc. ES4-4278-52R will provide you robust security strategy to the network.

Quality of Service (QoS)

To integrate voice, data and video service on one network, ES4-4278-52R applies Quality of Service (QoS) policies. Administrator can designate the priority of the traffic to achieve voice and video application always clear, smooth and jitter free.

Enterprise Level Management Features

ES4-4278-52R supports various user-friendly standard management features，such as intuitive web-based Graphical User Interface（GUI）or industry-standard Command Line Interface(CLI). Moreover, SNMP (v1/2c/3) and RMON support enables the switch to be polled for valuable status information and send traps on abnormal events. This sharing of vital management information saves time and money. Link aggregation, spanning tree protocol（STP/RSTP/MSTP）and IGMP Snooping features build a stable, smooth and resilient network for enterprise customers.
