Huawei LS5D00E2XX00 S5300 series Switch / Carrier Ethernet Line Card

The Huawei LS5D00E2XX00 (material code 03020LUB) is a 2-Port 10GE XFP Optical Front Interface Card used in the Huawei S5300 series Ethernet switches. It provides two 10 Gigabit Ethernet ports via pluggable XFP optical transceivers, giving the S5300 chassis additional high-speed uplink or inter-switch link capacity for campus and metro Ethernet deployments where standalone fixed-port switches are outgrown. As a line card it fits into a dedicated interface slot on the S5300 platform, drawing switching fabric capacity from the chassis backplane and working alongside the switch’s other fixed and modular interface cards. The S5300 series has been a widely deployed mid-range access/aggregation switch platform for Huawei, and this specific interface card is directly listed by multiple specialist Huawei parts resellers under its exact designation, confirming both its function and platform compatibility. Tested secondary-market cards such as this one provide a cost-effective way to restore or expand 10GE port capacity on an existing S5300 chassis without a full switch replacement.
