Functions and features of the LSH7X74BX1S0
Functions and Features
Description
Basic function
The card provides data packet processing and traffic management on 24 GE electrical ports, 48 10GE optical ports and 2 25GE optical ports.
Maximum port density
If all LPUs are such cards:
The S16700-4 chassis provides up to 8 x 25GE ports, 192 x 10GE ports, and 96 x GE ports.
The S16700-8 chassis provides up to 16 x 25GE ports, 384 x 10GE ports, and 192 x GE ports.
10/100/1000BASE-T port
A 10/100/1000BASE-T Ethernet electrical interface works in GE mode and supports 10M/100M auto-sensing.
10GE SFP+ optical port
When the 10GE SFP+ optical ports work in 10GE mode, they support SFP+ 10GE optical modules and 10GE copper modules, 10GE high-speed cables, and AOC cables.
When the 10GE SFP+ optical ports work in 2.5GE mode, they support SFP 2.5GE optical modules.
When the 10GE SFP+ optical ports work in GE mode, they support SFP GE optical modules and 1000BASE-T copper modules. When using a 1000BASE-T copper module, a port supports 100M/1000M auto-sensing.
25GE SFP28 optical port
When the 25GE SFP28 optical ports work in 25GE mode, they support SFP28 25GE optical modules, 25GE high-speed cables, and AOC cables.
Hot swapping
Supported
Restrictions and remarks
Only the four-SFU mode is supported when the switch blade is used.

LSH7X74BX1S0 FAQ
Q1: Which optical modules are supported? Can existing 1GE SFP optical modules be reused?
A1: Supports Huawei SFP series 1GE optical modules (SR/LR). Existing 1GE optical modules can be directly reused, eliminating the need for additional procurement and reducing networking costs.
Q2: What is the maximum number of terminals supported by a single service board?
A2: A single port can stably connect 20-30 terminals, and the 74 ports can support a total of 1400-2200 terminals, meeting the massive terminal demands of medium to large-scale access scenarios.
Q3: What are the differences between this board and the Huawei LSH7X48SX1S0 (48-port 1GE)?
A3: Higher port density (74 ports vs. 48 ports), 50% increased access capacity, suitable for medium to large-scale scenarios requiring massive gigabit access, and lower cost per port.
