Receives and transmits 100GE (supported by half of the ports)/40GE services.
40GE QSFP+ optical modules
QSFP+ to QSFP+ AOC cable
QSFP+ to 4*SFP+ AOC cable
QSFP+ to QSFP+ high-speed cable
QSFP+ to 4*SFP+ high-speed cable
When twelve 40GE ports (0, 1, 4, 5...) on the card work in 100GE mode, the following cables can be used:
100GE QSFP28 optical modules
QSFP28 to QSFP28 AOC cable
NOTE:
When a QSFP+ to QSFP+ high-speed cable is installed on a port, the cable can only be used as a cable of an M-LAG peer-link interface.
Functions and Features of the LSH7L24QX1E0
Functions and Features
Description
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 S16700-4 chassis provides a maximum of 96 40GE ports.
The S16700-8 chassis provides a maximum of 192 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 are in a group, and ports 12 to 23 are in 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 the 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 the 5+1 backup mode.

LSH7L24QX1E0 FAQ
Q1: Which optical modules are supported? Can existing 10G/1G optical modules be reused?
A1: Supports Huawei SFP28/SFP+/SFP series optical modules. 25G uses SFP28 (SR/LR), 10G uses SFP+, and 1G uses SFP modules. Existing 10G/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 40-50 terminals. A total of 24 ports can support 900-1200 terminals, meeting the needs of medium to large-scale aggregation scenarios.
Q3: What are the differences between this and the Huawei LSH7L36QX1E0?
A3: The number of ports is moderate (24 vs. 36), offering a better balance between capacity and cost. It is suitable for medium to large-scale scenarios that "do not require ultra-high density with 36 ports but need 25G speed upgrades," offering better cost-effectiveness.
