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.

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
ES1D2G48VX5S FAQ
Q1: Is it compatible with Huawei S9708 switches? Will there be bandwidth bottlenecks or performance degradation when 48 ports are simultaneously operating at full load for 10 Gigabit transmission?
A1: Fully compatible! Supports the entire S9300/S9700 series, backplane bandwidth ≥480Gbps, low power consumption design without sacrificing performance, no bottlenecks when operating at full load for 10 Gigabit transmission, meeting the high-performance requirements of large-scale networks;
Q2: How is the transmission stability over 30km when deployed with single-mode fiber optics for backbone networks? What are the specific advantages of low power consumption?
A2: Signal attenuation <0.5dB within 30km, no packet loss, no latency fluctuations; single-board power consumption ≤65W, 35% lower than ordinary high-end 10 Gigabit switches (approximately 100W), saving approximately 4200 RMB in electricity costs annually for 10 boards;
Q3: How to choose between 24/32-port / ordinary high-end 10 Gigabit / 100G line boards?
A3: 24 ports are suitable for less than 30 10 Gigabit devices, and 32 ports are suitable for 30-40 devices. The regular 10 Gigabit version is not energy-efficient, and the 100G version exceeds the budget. For more than 40 10 Gigabit devices, transmission speed of ≤40km, and high-end energy-saving requirements, this product is the best choice.
