Basic function
The card provides data packet processing and traffic management on 24 40GE optical ports, which can be split into 96 10GE optical ports.
Maximum port density
If all LPUs are these cards:
The CloudEngine 16804 chassis provides a maximum of 96 40GE ports.
The CloudEngine 16808 chassis provides a maximum of 192 40GE ports.
The CloudEngine 16816 chassis provides a maximum of 384 40GE ports.
40GE port
A 40GE port on the card can be split into four 10GE ports. That is, a card provides a maximum port density of 96 x 10GE. All the 24 40GE ports are independent, and each can be split into four 10GE ports. On the card, the 12 40GE ports that can be used as 100GE ports are marked with silkscreen 40/100G. Their IDs are: 0, 1, 4, 5, 8, 9, 12, 13, 16, 17, 20, and 21. These port IDs are represented by (0, 1, 4, 5...) in the following descriptions. The 24 ports on the card are divided into groups, each of which contains four ports starting from port 0. The total port rate of a group cannot exceed 200GE. When port n is used as a 100GE port, port n+2 becomes unavailable and is in DOWN(Port unavailable) state. For example: Ports 0 to 3 are in the same group. If ports 0 and 1 are used as 100GE ports, ports 2 and 3 become unavailable and are in DOWN(Port unavailable) state. If only one port (for example, port 0) is used as a 100GE port, port 2 becomes unavailable and is in DOWN(Port unavailable) state. Ports 1 and 3 can work as 40GE ports or each of them can be split into four 10GE ports.
Hot swapping
Supported
Restrictions and remarks
Ports 0 to 11 form a group, and ports 12 to 23 form another group.
When the total port bandwidth of each group does not exceed 480 Gbit/s, SFUs can forward data at the line rate in 4+1 backup mode.
When the total port bandwidth of each group does not exceed 600 Gbit/s, SFUs can forward data at the line rate in 5+1 backup mode.

CEL24LQFD-EK FAQ
Q1: Which Huawei switch models does the CEL24LQFD-EK support? How compatible is it?
A1: It mainly supports Huawei CE12800 series flagship switches (such as CE12816/CE12812) and CE9800 series high-end switches (such as CE9866-128DQ). The interfaces and slots are fully matched, with 100% compatibility; simply plug it in and it's ready to use.
Q2: Can 400G and 200G optical modules be used simultaneously on the 24 ports? What is the long-distance transmission range?
A2: It supports independent port rate negotiation and can use 400G and 200G optical modules simultaneously. With corresponding long-distance optical modules, it can achieve transmission distances from 10km (LR4) to 40km (ER4), flexibly adapting to different cross-regional distance requirements.
Q3: How are the power consumption and heat dissipation performance of this interface card? Is stability affected under long-distance transmission?
A3: Adopts a low-power optimized design, with single-card power consumption controlled at a low level compared to similar flagship long-distance interface cards in the industry, and is compatible with the redundant heat dissipation system of the switch; long-distance transmission supports FEC error correction and anti-interference optimization, and stability is not affected by distance.
