Reliable 10G connectivity for S5720HI.
Stable SFP plus interfaces.
Good performance under load.
Easy installation.
Predictable throughput.
Solid expansion option.
The ES5D21X04S01 is a high-performance expansion module offering four 10 Gbps SFP+ ports designed for Huawei S5720HI series switches.
The ES5D21X04S01 is compatible with all S5720HI, S5720HI-EI, and S5720HI-SI switch models that feature an available expansion slot.
It provides four 10 Gbps SFP+ ports, up to 40 Gbps aggregate throughput, typical power consumption of 8 W, and supports both fiber and DAC modules.
Power off the switch, slide the card into the expansion slot, secure it with screws, restore power, and verify recognition via the CLI or web management interface.
Yes, it fully supports industry-standard 10 G SFP+ optical transceivers and DAC cables for maximum deployment flexibility.
With single-mode optics up to 10 km, multimode optics up to 300 m, and DAC cables up to 7 m.
Yes, the ES5D21X04S01 supports hot-swapping, allowing you to install or replace the card without interrupting network operations.
The card consumes approximately 8 W under full load and operates reliably in temperatures from 0 °C to 50 °C.
Download the latest firmware from Huawei’s support site, upload it to the switch via TFTP/FTP, and apply it using the CLI’s upgrade command.
Use the “display interface transceiver” CLI command or view the web UI’s module status page to confirm link status, module type, and optical power.
The interface card includes a one-year limited warranty and lifetime technical support through Huawei’s official service channels.
It’s sold through authorized Huawei resellers, the Huawei online store, and major global IT hardware distributors.
By adding four 10 Gbps uplinks, it increases aggregate bandwidth and enables seamless integration of high-speed links in your S5720HI deployment.
Each SFP+ port delivers up to 10 Gbps, with a combined forwarding capacity of 40 Gbps on the card.
The card is certified for use with major third-party 10 G SFP+ modules, though Huawei-branded transceivers are recommended for optimal performance and warranty compliance.
It complies with IEEE 802.3ae (10G Ethernet), RoHS, CE, and FCC standards, ensuring performance reliability and regulatory compliance.
Power off the switch, gently remove dust with a dry anti-static brush, avoid liquids, inspect connector integrity, and resume operation in a clean environment.
