Stack card provides stable high speed stacking.
QSFP plus interfaces work flawlessly.
Improved switch stacking reliability.
Easy installation with included cable.
Consistent stacking performance.
A dependable stacking solution.
The LS5D21VST000 is a dedicated stacking module featuring two QSFP+ ports and includes a 1 m QSFP+ cable, designed exclusively for Huawei S5320EI Series switches.
The LS5D21VST000 is fully compatible with all Huawei S5320EI Series switches, enabling seamless stacking and unified management.
Power down the S5320EI switch, insert the LS5D21VST000 module into the stack card slot, secure with screws, reconnect power, and enable stacking via CLI or web GUI.
Each QSFP+ port supports 40 Gbps, delivering a total bidirectional stacking bandwidth of up to 80 Gbps for high-performance aggregation.
Yes. You can create a stack of up to four S5320EI switches using LS5D21VST000 modules and QSFP+ cables in a ring or chain topology.
Yes. The provided 1 m QSFP+ direct-attach cable supports hot-swap operations without disrupting switch uptime or traffic.
Only Huawei-certified QSFP+ cables are recommended to guarantee signal integrity and full stacking performance with LS5D21VST000 modules.
Using the included 1 m DAC cable, you can stack switches up to 1 meter apart. For longer distances, use Huawei optical QSFP+ transceivers and fiber cables.
Yes. Ensure your S5320EI switch is running VRP version V200R019C00 or later to support LS5D21VST000 stacking features.
Use the "display stack" CLI command or the web GUI stack status page to confirm member IDs, role hierarchy, and link health.
In the event of a link failure, the stack automatically reroutes traffic through the remaining active link, ensuring uninterrupted data flow.
No. Only identical LS5D21VST000 modules should be used in the same stack to maintain consistent interface and bandwidth characteristics.
The LS5D21VST000 card consumes approximately 4 W, with negligible impact on the overall power budget of an S5320EI switch.
Yes. Each QSFP+ port can be used for native 40 GbE uplinks to aggregation switches or servers, in addition to stacking.
The LS5D21VST000 is backed by Huawei’s standard three-year hardware warranty and local support services.
LS5D21VST000 delivers high-speed 80 Gbps stacking, simplified unified management, hot-swap capability, and reduced cabling complexity for S5320EI deployments.
