CEL48XSEGA-E (48-port 10GE, 4-port 100GE Ethernet optical interface board (EGA, SFP+, QSFP28))
Overview of veneers
The CEL48XSEGA-E board provides data access and processing on 48 10GE service optical interfaces and four 100GE/40GE uplink optical interfaces.
Functions and features
CEL48XSEGA-E boards are suitable for access layers in data center networks that require high density, performance, and continuous system operation.
CE-MPUA-E (Master Processing Unit, CE12804E/CE12808E/CE12816E chassis)
Overview of veneers
As the main control unit on the CE12804E/CE12808E/CE12816E chassis, the CE-MPUA-E is mainly responsible for the control, management and monitoring of the system.
Functions and features
The CE12800E series switches are designed with a separate control plane, data plane, and monitoring plane.
As the core of control, management, and monitoring of the CE12800E series switch system, the CE-MPUA-E board is responsible for the system control plane and related functions of the monitoring plane, including device management, route calculation, and monitoring.
CE-SFU04C-E（交换网板，CE12804E机框）
Overview of veneers
As a switching unit on the CE12804E chassis, the CE-SFU04C-E is mainly responsible for wire-speed switching of the system data plane. The CE12804E chassis is equipped with six SFUs and uses the load-sharing redundancy backup mode to improve the reliability of the system.
Most of the SFUs are installed on the back of the switches, which have no interfaces and are mainly responsible for the wire-speed switching of the data plane of the system. The SFB connects the master controller and the service board to increase the switching capacity, such as cross-chassis forwarding.
Functions and features
CE12804E switches are designed with a separate control plane, data plane, and monitoring plane.
As the switching unit on the CE12804E switch, the CE-SFU04C-E is mainly responsible for the data line-speed switching of the system data plane.
