Product Overview

The Digital China DCRS-5750 series switches are 10G IPv6 Ethernet Layer 3 lite switch. There are 6 types switch for this family. The product family includes DCRS-5750-28T,  DCRS-5750-52T, DCRS-5750-28T-DC, DCRS-5750-52T-DC, DCRS-5750-28T-POE and DCRS-5750-52T-POE. All products support IPv6 with hardware and pass the IPv6 form certification Phase II. All products comply with the RoHS standard.

The DCRS-5750 series products are ideal for aggregation layer of large networks or core layer device of small networks. The DCRS-5750 series products include over 24 GE/48GE ports and max 4 10GE ports can deployed in Data Center application, gigabit to desk application, L3 to edge application.

Key Features and Benefits

Performance and Scalability

  1. DCRS-5750 series switch support wire-speed L2/L3 forwarding and high routing performance for IPv4 and IPv6 protocols. 
  2. Support up to 4 optional 10G ports, which is accomplished via a hot-pluggable 10 Gigabit XFP/SFP+ transceiver.
  3. The DCRS-5750-28T-DC/52T-DC switch supports redundant AC and DC power supplies for different environment applications.

L3 Features

  1. The DCRS-5750 series switch delivers high-performance, hardware based IP routing.
  2. RIPv1/v2, static and default route provide dynamic routing by exchanging routing information with other Layer 3 switches and routers.

 Powerful  Multicast

  • The DCRS-5750 support abundant multicast features. The product support rich multicast features such as IGMPv1/v2/v3 and snooping etc. As the rich application experience, the product support multicast vlan register and multicast receive control and illegal multicast source detect functions.

 Easy high reliability network

  1. MRPP is Multi-layer Ring Protection Protocol, which is DCN’s private fast Ethernet ring protocol. Comparing to spanning tree protocol, it has advantages of fast convergence, simple protocol calculation, little system resources cost, clear networking idea and so on, which can improve the reliability of Ethernet network operation.
  2. VRRP is a high reliability protocol for network, which can help customer network increase network reliability and upgrade network more smoothly.

 Comprehensive QoS

  1. 8 queues per port enable differentiated management of up to 8 traffic types.
  2. Traffic is prioritized according to IEEE802.1p, DSCP, IP precedence and TCP/UDP port number, giving optimal performance to real-time applications such as voice and video.
  3. Bi-directional rate-limiting, per port or traffic class, preserves network bandwidth and allows full control of network resources.

 Expedient Management

  1. DCRS 5750 series support DDM (Digital Diagnostic Monitor), which makes the detailed digital diagnostic function standard in SFF-8472 MSA. DDM is more requested by carrier users.
  2. DCRS 5750 series support OAM to improve the effectively management mechanism, which greatly extends Ethernet application to Metropolitan Area Network and Wide Area Network by implementing OAM on Ethernet

 Enhanced Security

  1. IEEE 802.1X port-based access control and MAC-based access control ensure all users are authorized before being granted access to the network.
  2. Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets based on L2/L3/L4 headers information. And for some service is based on time, the product can support time based ACL to match the requirement.
  3. Secure Shell (SSH) encrypts network management information via Telnet providing secure network management.
  4. RADIUS Authentication enables centralized control of the switch and restricts unauthorized users from altering the configuration of the switch.

 POE support

  1. With the RPS(Remote Power Supply) connect, the DCRS-5750-28T-POE/52T-POE can support POE (Power Over Ethernet) technical and connect to wireless AP, IP phone and Network Camera.
  2. The DCRS-5750-28T-POE/52T-POE can support 24/48 port POE at same time and the MAX 15.4W power of each port with RPS support. The product can define the power of each port to save the power and set port priority for each port.

 Abundant IPv6 Support

  • The DCRS-5750 series switch supports IPv6 routing in hardware for maximum performance. As more network devices growing and the need for larger addressing and higher security become critical, the DCRS-5750 series switch will be a right product to meet the requirement. The DCRS-5750 passed IPv6 form Phase II certificate is the best proof of the application.
