Functions and Features
Description
Basic function
The card provides data packet processing and traffic management on 12 40GE optical ports, which can be split into 48 10GE optical ports.
Maximum port density
If all LPUs are these cards:
The S16700-4 chassis provides a maximum of 48 40GE ports.
The S16700-8 chassis provides a maximum of 96 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 48 x 10GE. All the 12 40GE ports are independent, and each can be split into four 10GE ports.
On the card, the 6 40GE ports that can be used as 100GE ports are marked with silkscreen 40/100G. The port IDs are 0, 1, 4, 5, 8, and 9. These port IDs are represented by (0, 1, 4, 5...) in the following descriptions.
The 12 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
Only the four-SFU mode is supported when the switch blade is used.
When the total port bandwidth of each group does not exceed 480 Gbit/s, SFUs can forward data at the line rate in the 3+1 backup mode.

LSH7L12QX1S0 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 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 12 ports can support 360-480 terminals, meeting the needs of small to medium-sized aggregation scenarios.
Q3: What are the differences between this and the Huawei LSH7L24QX1E0?
A3: Fewer ports (12 vs. 24), focusing on entry-level 25G needs, with a lower price, suitable for small to medium-sized scenarios and branch nodes that do not require large-scale expansion.
