Huawei Switch Modules & Cards

A

A Huawei switch module & card is a hot-pluggable hardware component that expands port density, service processing and fabric connectivity on Huawei modular switches for flexible network scaling.

A

Huawei offers line cards, service modules, fabric cards, power modules and high-density interface cards, each designed to add ports, processing features or internal backplane capacity.

A

Select modules by port speed (1G/10G/40G/100G), required features (QoS, ACL, MPLS), chassis compatibility and forecasting growth to ensure optimal performance and investment protection.

A

Yes. Most Huawei switch modules & cards support hot-swap installation and removal without powering down the chassis, enabling non-disruptive upgrades and maintenance.

A

Power down the switch if required, unlock the module slot, slide the card evenly into the guide rails until it clicks, then lock the slot and power up the chassis following the CLI prompts.

A

Huawei fabric modules & cards provide low-latency, high-bandwidth internal switching, exceptional forwarding capacity and non-blocking architecture to support large-scale data center fabrics.

A

Huawei offers 100GbE QSFP28 line cards and fabric cards compatible with CloudEngine and S-series chassis, delivering up to 1.6Tbps per slot for high-performance aggregation.

A

Many Huawei switch modules & cards maintain backward compatibility within the same chassis family, but always verify interoperability matrices and firmware requirements before deployment.

A

Download the latest firmware from Huawei Support, upload it to the switch via FTP/TFTP, and execute the 'upgrade' command in the CLI to update modules and cards seamlessly.

A

Huawei switch modules & cards come with a standard one-year warranty and optional extended support plans up to five years, covering hardware defects and firmware updates.

A

Mixing modules across different series is only supported when officially listed in the compatibility matrix; mismatched modules may cause performance issues or become unsupported.

A

Operate modules in 0–45°C (32–113°F), 5–95% non-condensing humidity and 5000 m maximum altitude to ensure reliability and compliance with Huawei environmental specifications.

A

Check slot status with 'display slot' CLI, inspect LEDs for errors, reseat the module, update firmware and consult logs; replace the card if hardware faults persist.

A

Huawei offers AC and DC hot-swappable power modules rated from 300W to 2400W, ensuring N+1 redundancy and supporting full-load operation for various chassis models.

A

Huawei service modules provide hardware-accelerated ACLs, MACsec encryption, firewall engines and DPI, ensuring comprehensive traffic inspection and protection at line rate.
