LST7G48SX6S0 FAQ
Q1: What are the core advantages of this service board? Is it suitable for small to medium-sized networks with limited budgets?
A1: The core advantages are its high cost-effectiveness with 48 ports, dual-rate compatibility, low power consumption, and flexible expansion; precise cost control eliminates the need to pay for redundant functions, making it ideal for small to medium-sized networks with limited budgets.
Q2: Which optical modules does it support? Can it directly connect to existing 1G legacy equipment?
A2: It supports Huawei standard SFP+ 10G optical modules (SR/LR/ER) and SFP 1G optical modules; dual-rate adaptive, it can directly connect to existing 1G equipment without additional converter configuration.
Q3: How does its energy consumption and cost performance compare to other 48-port 10G boards of the same level?
A3: The total power consumption is ≤185W, saving 30% more energy than comparable products; procurement costs are reduced by 20%-25% while ensuring basic forwarding performance, resulting in outstanding cost-effectiveness.
Q4: What size network scenarios is it suitable for? Is installation complex?
A4: Suitable for small and medium-sized data centers, medium-sized parks, and county-level aggregation of operators; supports hot-swapping, installation without downtime, automatic speed recognition after insertion into the switch, and simple configuration.
