In terms of modular design, how to ensure the scalability of switch series PDU？

In terms of modular design, ensuring the scalability of the switch series PDU is a key goal. First, the key is to ensure module independence. Each functional module should be a relatively independent unit without being overly coupled to each other. This design allows different modules of the system to be added, replaced or upgraded independently without unnecessary impact on the entire system.

Secondly, adopting standard interface specifications is an important step in achieving scalability. Standard interfaces ensure compatibility between modules, allowing new modules to be easily integrated into existing systems. The pluggable design is also a key element, allowing modules to be easily plugged in or out without shutting down the entire system. This design enables the system to dynamically add or replace modules during runtime, improving the system's flexibility and scalability.

In addition, designing flexible power sockets is also key to ensuring scalability. This includes flexibility in the number, type and power of outlets to accommodate different scenarios and changes in power demand. Reserving expansion space is also an important consideration, including sufficient physical space, power capacity, and cooling capabilities to ensure that the system has sufficient resource support when additional modules are needed in the future.

In addition, network scalability should also be fully considered. Ensure modules can be easily integrated into larger network management systems, using standard network protocols and interfaces to help expand network connectivity when needed. Supports module firmware and software upgrades to improve system performance, introduce new features, or fix potential problems without replacing hardware. Finally, in modular design, adequate testing and verification are also key to ensure the independence, compatibility and performance of each module and ensure that the scalability of the system meets actual needs.
