19"-switch with 24 optical ports with management and DMS
  • 19" L2/L3 Switch with 24 optical
  • Copper ports: 4 x 10/100/1000Mbits/s
  • with management, ring-capable, L3 functions, DMS
  • Power supply 230VAC and 48VDC, redundant

Being developed for tasks with high data volume, this layer-2/3 switch with L3 functions is suitable for example for video over IP and video streaming in connection with multicast as well.  The high number of optical ports allow the use of the RY-LGS025-24 for remote units, as per example IP-cameras. With its extensive management possibilities, it is also suitable for complex network structures.

Video network special features

High backplane performance for a fluid video transmission with full port allocation. Support of jumbo frames up to 9600Bytes also with 100MBit/s. Port security through restriction of MAC-addresses.


DMS (Device Management System)

This switch disposes of an integrated network monitoring and control system which gives the user a good overview over the whole network in an easy way. This DMS-system has the following qualities:

Graphical network map 
The network map gives a quick overview over all switches and terminal devices such as IP-cameras or servers indicating the IP-address, type of device and equipment. Plans and maps can be saved as background pictures and thus enable the user to access to certain devices without knowledge of the entire IP-structure. 

Device search

This function enables the access to a specific device also in large networks. Recently added devices, as per example a new IP-camera, are immediately displayed and thus enable a direct access. 

Data traffic display

Graphical display of data traffic per port in a time axis. 

Error handling and security

Network diagnosis between master switch and terminal devices. Protective mechanisms such as data flow restriction guarantee an effective protection against inadvertent access. IEEE802.3ah and IEEE802.1ag provide tools for structuring of networks.
