Huawei optical modules—including SFP, eSFP, SFP+, XFP, QSFP+, QSFP28, and CFP modules—are designed to be hot-swappable, meaning they can be inserted into or removed from powered switches, routers, or other network devices without requiring a system reboot or shutdown (Huawei datasheets) . This feature ensures minimal network downtime and simplifies maintenance and upgrades.
Hot-swappable modules comply with Multi-Source Agreement (MSA) standards, which define mechanical, electrical, and management interfaces to ensure safe insertion/removal, signal integrity, and electrostatic discharge (ESD) protection . Modules are engineered to prevent inrush currents and maintain proper impedance and thermal management during live operation.
Enhanced small form-factor pluggable (eSFP) modules are hot-swappable, low-speed optical modules with the monitoring function.
