Huawei CX22E4GF Switch / Carrier Ethernet Line Card

The Huawei CX22E4GF is a 4-port Gigabit SFP expansion module for Huawei’s S5300 series switches, confirmed by both the supplier’s own specification and independent reseller listings describing it as a quad-port fibre expansion module for this platform. The module adds four additional Gigabit Ethernet SFP-based optical ports to a compatible S5300-series switch, giving network engineers extra fibre uplink or interconnect capacity beyond the switch’s fixed copper ports without needing to replace the whole unit. As a slot-in expansion card, the CX22E4GF installs into a dedicated expansion bay on the S5300 chassis, consistent with Huawei’s modular approach to extending fixed-configuration switches with additional port types as network requirements change. The S5300 series is a widely deployed family of enterprise and campus gigabit Ethernet switches. Tech-Star (UK-based, shipped worldwide) supplies tested Huawei switch expansion modules for engineers maintaining S5300-series deployments.
