Functions and Features
Description
Basic function
The card provides data packet processing and traffic management on 24 x 100GE 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 S16700-4 chassis provides a maximum of 96 100GE ports.
The S16700-8 chassis provides a maximum of 192 100GE 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 100GE, 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.
Hot swapping
Supported
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.

LSH7C24HX2E0 FAQ
Q1: Which optical modules are supported? Can existing 1G optical modules be reused?
A1: Supports Huawei SFP+/SFP series optical modules. 10G uses SFP+ (SR/LR), and 1G uses SFP modules. Existing 1G optical modules can be directly reused, reducing upgrade costs.
Q2: What is the maximum number of terminals supported by a single service board?
A2: A single port can stably connect 30-40 terminals. A total of 24 ports can support 700-900 terminals, meeting the needs of medium to large-scale aggregation scenarios.
Q3: What are the differences between this board and Huawei LSH7C36HX2E0/LSH7D18DX2E0?
A3: The number of ports is moderate (24 vs 36/18), offering a better balance between capacity and cost, suitable for medium to large-scale scenarios that "do not require ultra-high density but need more ports than 18."
