CE-L24CQJ Datasheet
Item
CE-L24CQJ
Basic function
The card provides data packet processing and traffic management on 24 x 100GE optical ports or 16 x 200GE optical ports, which can be used as 24 x 40GE optical ports or split into 96 x 25GE or 96 x 10GE optical ports.
Maximum port density
If all LPUs are these cards:
The CloudEngine 16804 chassis provides a maximum of 96 100GE ports or 64 200GE ports.
The CloudEngine 16808 chassis provides a maximum of 192 100GE ports or 128 200GE ports.
The CloudEngine 16816 chassis provides a maximum of 384 100GE ports or 256 200GE ports.
100GE port
100GE ports on the card support QSFP28 and QSFP+ optical modules. A 100GE port can be used as a 40GE port through auto-sensing, or split into 4 x 25GE or 4 x 10GE ports. The card can provide a maximum port density of 24 x 40GE, 96 x 25GE, or 96 x 10GE. Each 100GE port can be used as a 40GE port through auto-sensing. Every two ports (0-1, 2-3, 4-5, 6-7, 8-9, 10-11, 12-13, 14-15, 16-17, 18-19, 20-21, and 22-23) form a group. The two ports in a group need to be split together, and each port can be split into 4 x 25GE or 4 x 10GE ports.
200GE port
16 ports can work at the rate of 200 Gbit/s and are divided into 8 groups (0 and 1, 2 and 3, 4 and 5, 6 and 7, 12 and 13, 14 and 15, 16 and 17, and 18 and 19). Such a port works at the rate of 100 Gbit/s by default. You can run the port mode 200GE command to change the port rate to 200 Gbit/s. After the port rate is changed, the port supports QSFP56 optical modules and can work as a 100GE or 40GE port through auto-sensing. The port can be split into two 100GE ports. When the rate is changed for either port in a port group, the other port in the group automatically switches to the same rate. For example, when port 0 is configured to work at the rate of 200 Gbit/s, port 1 is automatically configured to work at the rate of 200 Gbit/s.
Hot swapping
Supported
Restrictions and remarks
Every 12 ports form a group, and two groups (ports 0 to 11 and 12 to 23) are involved. Each group has a bandwidth limit.
Only the first eight ports in each group can be configured to work at the rate of 200 Gbit/s.
In 3+1 SFU mode, the maximum bandwidth of each group cannot exceed 1.2 Tbit/s (for example, 6 x 200 Gbit/s or 12 x 100 Gbit/s).
In 4+0 SFU mode, the maximum bandwidth of each group cannot exceed 1.6 Tbit/s (for example, 8 x 200 Gbit/s or 8 x 100 Gbit/s + 4 x 200 Gbit/s).
MACsec
Ports 0 to 7 and 12 to 19 support MACsec. When these ports are configured to work at 40 Gbit/s or are split, MACsec is still supported. Other ports do not support MACsec.

CE-L24CQJ FAQ
Q1: Which Huawei switch models does the CE-L24CQJ support? How compatible is it?
A1: It mainly supports Huawei CE12800 series mid-to-high-end switches (such as CE12804/CE12808), CE8800 series high-end switches (such as CE8850-64CQ-EI), CE7800 series high-end switches, and some models of the CE9800 series. The interfaces and slots are fully matched, with 100% compatibility; simply plug it in and use.
Q2: Do the 24 100G ports support backward compatibility with low-speed optical modules? Can existing optical modules be reused?
A2: It supports 100G/40G/25G/10G multi-rate auto-negotiation. Existing 40G, 25G, and 10G optical modules can be used directly without additional purchase, effectively reusing existing assets and reducing upgrade costs.
Q3: How are the power consumption and heat dissipation performance of this interface card? Will it place an additional burden on the switch? A3: It adopts a low-power design, with single-card power consumption controlled at a low level compared to similar high-density 100G interface cards in the industry. It is also compatible with the switch's built-in cooling system, requiring no additional cooling measures and not putting extra pressure on the switch's heat dissipation.
