Switching and Routing Devices



Layer Managed 24x1GE + 4x1GE SFP PoE+ Switch

PN-CMS24GE4SFP PoE+ extends its L2 features with value-add Carrier Ethernet Features such as G.8032 and 1588v2 PTP to provide customers a product that is best combination of features, performance and value for Industrial, Enterprise and Carrier networks via fiber or copper connections. Moreover, the traffic shaping utility allows customers to reduce bandwidth requirements by smoothening the traffic.

Device has 24(10M/100M/1G) ports and 2 SFP+ ports. PoE+ can be provided through 24 (10M/100M/1G) RJ45 copper ports and supports 802.3at/af/bt total up to 720W PoE budget. Moreover, the device has RJ45 Console (RS232) port for management and USB port for ease of management. The USB port provides temporary configuration application through a configuration file placed in USB. In addition, the device also supports software update through USB without any user interaction. The fault relay interface is also placed on the device for managing connections under various scenarios. The outfit of the device is designed to be suitable for DIN-Rail mount which is ideal for Industrial applications.

Sectors and Applications

Supported Technologies

Exceptional Precision with IEEE 1588v2 (TC, BC) and Sync-e (Optional)

The switch performs both IEEE1588v2 and Sync-e, including transparent and boundary clock capabilities, implementations in hardware, so there is no performance penalty on packet processing. The hardware architecture ensures low latency and high time accuracy – which is critical for delay-sensitive industrial, power, backbone and finance applications.

G.8032 Ethernet Ring Protection Switching (ERPS)

G.8032 provides recovery time of sub-50ms up to 25 nodes for improved resiliency in security applications such as border surveillance applications.

802.3at Power PoE+ Support (Optional)

The switch provides up to 30 W per port which reduces the number of ports required for integration of high power devices into network.
