1.1 Overview
MRI-128-F4G-PSE/24 is rackmount High-Port Density and Gigabit Managed
Industrial PoE Switch, designed exclusively for highly critical PoE applications
such as real time IP video surveillance with high resolution quality and the
evolving wireless communication systems such as Wimax and 802.11 a/b/g/n
Access Points.The 24 Fast Ethernet PoE injector ports of the switch can deliver
15.4W by IEEE 802.3af or 30W by the High Power PoE IEEE 802.3at.
The 4 Gigabit Ethernet ports provide high speed uplink to connect with higher
level backbone switches. With the MSR network redundancy technology, the
switches can aggregate up to 12 fast ethernet and 2 gigabit rings while
providing high quality data transmission with less than 300ms network
recovery time. Furthermore, to ensure the traffic switching without data loss
and blocking, the switch provides 12.8G backplane with the integtrated
non-blocking switching function. It incorporates LLDP function and perfectly
works with the NMS for allowing administrators to automatically discover
devices and efficiently manage the industrial network performance in large
scale surveillance networks. To further ensure the non-stop power delivery, the
switch supports dual 48VDC power inputs and provides alarm relay output
signaling function. For high voltage requiring applications the PoE switch
provides extra 90~264VAC or 127~370VDC power supply capability.
With the advanced Layer2 management features including IGMP
Query/Snooping, DHCP, 256 VLAN, QoS, LACP, LPLD, etc. and the corrosion
resistant robust design, the switch highly outstands from other PoE switches
and becomes the revolutionary solution for industrial surveillance applications.
