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.

S7703 PoE FAQ
Q1: What is the maximum number of PoE terminals supported by the Huawei S7703-POE? What are its dimensions?
A1: It supports a maximum of 144 PoE terminals (3 x 48-port PoE boards); the dimensions are 442mm × 476mm × 130mm, a compact design suitable for small to medium-sized data centers.
Q2: Is the PoE power supply adjustable? Does it support power outage recovery?
A2: It supports adaptive PoE power adjustment, allocating 30W/60W power according to terminal needs; equipped with dual power modules, it automatically switches to backup power after a power outage to ensure continuous power supply to PoE terminals.
Q3: Compared to the S7706-POE (6 slots) and mid-range PoE switches, what are the advantages of the S7703-POE? A3: Half the size and 35% cheaper than S7706-POE, suitable for small and medium-sized scenarios; twice the switching capacity of mid-range PoE switches, supporting more terminal access, and has core-level forwarding performance.
