The S7700 series switches (S7700 for short) are high-end smart routing switches designed for nextgenerationenterprise networks. The S7700 design is based on Huawei’s intelligent multi-layer switching technology to provide intelligent service optimization methods, such as MPLS VPN, traffic analysis, comprehensive H-QoS policies, controllable multicast, load balancing, and security, in addition to high-performanceLayer 2 to Layer 4 switching services.

Maximum power:
When the card is used on a non-PoE chassis: the card does not provide PoE power supply.
When the card is used on a PoE chassis of S7703, S7706, or S7712: 60 W for each port and 1776 W for the whole card
When the card is used on the S7703 PoE or S7706 PoE: 60 W for each port and 2880 W for the whole card
LSS7G48VX5E0 FAQ
Q1: Is it compatible with the Huawei S12708 switch? Will there be a bandwidth bottleneck when all 48 ports are simultaneously operating at full load for 10 Gigabit transmission?
A1: Fully compatible! Supports the entire S12700 series, with backplane bandwidth ≥480Gbps. Full load 10 Gigabit transmission has no bottlenecks, meeting the centralized 10 Gigabit access needs of large networks.
Q2: How is the transmission stability over 30km when deployed with single-mode fiber optics for the backbone network? How much of a price advantage does it have compared to comparable high-end models?
A2: Signal attenuation <0.5dB within 30km, with no packet loss and no latency fluctuations; the price is 30% lower than comparable high-end 10 Gigabit models and 60% lower than 100G models, offering the best cost-performance ratio for 10 Gigabit upgrade scenarios.
Q3: How to choose between 24/32-port/100G/ordinary high-end 10 Gigabit line boards?
A3: 24 ports are suitable for less than 30 10 Gigabit devices, 32 ports are suitable for 30-40 devices. The 100G version is over budget, and the regular high-end version has a high premium. For more than 40 10 Gigabit devices, ≤40km transmission, and a controllable budget, this product offers the best cost performance.
