Adapter case: compatible with huawei CloudEngine in high-end switch box (such as CE6881 / CE6881K/CE7800 / CE8800 series), need to be used with corresponding chassis power supply module, business card

Working environment: Working temperature 0℃ to 45℃, storage temperature -40 ℃ to 70℃. Relative humidity 5% to 95% (no condensation), protection grade IP20 (built-in installation in the chassis)

Mechanical characteristics: Compatible with the standard main control slot of the switch, and the module size is compatible with the chassis. Supports hot plugging and is equipped with an independent heat dissipation module

Management capabilities: Supports Huawei iMaster NCE-Campus/CloudCampus unified management platform, and supports batch configuration distribution, firmware upgrade, fault monitoring, and traffic statistics; Support log auditing, alarm classification, and remote diagnosis

Function

Distributed main control and high-performance scheduling: As the control core of the switch, it independently undertakes protocol processing, routing calculation, and service resource scheduling tasks, and collaborates with service boards to achieve "control - forwarding separation", avoiding the main control bottleneck and ensuring the smooth carrying of multiple services (data, voice, video) in large-scale networks

1:1 Redundant hot standby and uninterrupted operation: Supports dual main control board card hot standby configuration. When the main board fails, the standby board can be seamlessly switched within ≤ 300ms. The configuration and session status are automatically synchronized, with no service interruption and no data loss, meeting the "zero interruption" requirement of the core layer network

Full protocol support and flexible networking: Compatible with IPv4/IPv6 dual-stack and rich routing and multicast protocols, it can be adapted to complex networking scenarios such as the core layer of the park and the aggregation layer of the data center, and supports cross-regional interconnection, VPN dedicated line access, public network exit routing and other functions

Unified management and intelligent operation and maintenance: Integrated with Huawei's unified management platform, it supports remote monitoring of the main control status, protocol operation status, and routing table information. It also supports fault classification alerts (such as abnormal board temperature and protocol down) and remote diagnosis, reducing on-site operation and maintenance workload

High security and stability guarantee: Supports management channel encryption (SSHv2, HTTPS), device identity authentication, configuration backup and one-click rollback; It is equipped with an internal anti-attack mechanism to resist CPU overload attacks and protocol message flooding, ensuring stable operation at the control level

Compatible expansion and smooth upgrade: Compatible with Huawei's mid-to-high-end switch chassis, it can be seamlessly matched with 10-gigabit service boards such as CE-L48XS-FD and power redundancy modules. Support the expansion of new protocols and functions through firmware upgrades to meet the demands of network upgrades and digital transformation

Application scenarios

The core layer of medium and large-scale parks: The core layer switches of large enterprise headquarters, industrial parks, and university campus networks, as the core components of the dual main control redundancy configuration, carry out the routing forwarding and service scheduling of each aggregation switch, ensuring the highly reliable access of tens of thousands of terminals

Data center access/aggregation layer: Access and aggregation layer switches for small and medium-sized data centers, combined with 10-gigabit / 25G service board cards to connect servers and storage devices. The dual main control redundancy design avoids service interruption in the data center caused by control layer failures

Government/state-owned enterprise office park backbone: Backbone switches for government agencies and large state-owned enterprises' office parks, supporting multi-area routing interconnection and business isolation (office network, government affairs network, monitoring network), with a highly reliable and redundant design that meets the "stability first" requirement of government affairs systems

Core networks in the medical and financial industries: Core switches for large hospital medical parks and regional bank data centers, carrying key services such as medical image transmission, remote consultation, and financial transaction data. Dual main control hot standby + rapid switching ensures business continuity

The core of multi-branch interconnection in enterprises: The core switch of the regional headquarters of large enterprises, which realizes cross-regional interconnection with the head office and various branches through BGP routing protocol and MPLS VPN. The high-performance routing computing capability of the main control board card supports complex network topologies

Park network upgrade and transformation: In the upgrade scenario of the original single main control switch, CE-MPUB-S is added to achieve main control redundancy, enhancing the reliability of the network control level. There is no need to replace the switch chassis and service boards, reducing the upgrade cost
