19"-L2 Switch with management, 24 ports PoE+, DMS
  • 19" Switch with PoE+ with DMS
  • 370W PoE
  • Copper ports: 24x10/100/1000TX with PoE+
  • Optical fibre ports: 4x100/1000SFP
  • with management, ring capable, layer 2, DMS
  • Power supply 230VAC

Being developed for tasks with high data volume, this layer-2 switch is suitable for example for video over IP and video streaming in connection with multicast as well. IP-cameras are supplied by PoE through the data cable. With its extensive management possibilities, it is also suitable for complex network structures.

Video network special features

Active monitoring of the camera 
Switch-powered cameras by PoE are constantly monitored. In case of a camera failure the switch automatically restarts the camera. If this is not possible the switch alarms by SNMP.  

Active monitoring PoE-supply 
The switch alarms by SNMP in case of sudden excessive power consumption by a defect camera for example.

Active management of the PoE-performance 
The PoE-ports can be started by time intervals so as to prevent an overload of the PoE power supplies. 

Video-friendly features
Extra high backplane performance for a smooth video transmission with all ports assigned. Support of Jumbo Frames up to 9600Bytes by 100MBit/s.  MAC-address restriction ensures port security.

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.
