LE0MPSD16 FAQ
Q1: Which Huawei switches is this power module compatible with? Does it support hot-swapping?
A1: It is exclusively compatible with the entire Huawei S9300 series (S9303/S9306/S9310/S9312, etc.); it supports hot-swapping and can be replaced online without interrupting device operation.
Q2: What scenarios is the 1600W power suitable for? What are its advantages compared to high/low power supplies?
A2: It is suitable for medium load scenarios (4-6 service boards) of S9300, branch offices, regional data centers, etc.; its advantages are precise power matching, controllable cost, and adaptability to limited power supply environments, resulting in higher cost-effectiveness.
Q3: What is the input voltage range? Does it support redundant power supply?
A3: The input voltage is compatible with AC 100-240V/DC -48V, adapting to different data center power supplies; it supports N+1 redundancy mode to improve power supply reliability in medium load scenarios.
Q4: How do I determine if I need to select this 1600W power module? Is the installation complicated?
A4: When the S9300 is equipped with 4-6 service boards, the power supply in the data center is limited, or an old 1600W power supply needs to be replaced, it is recommended to choose this option; no professional tools are required for installation, just insert it directly into the S9300 power supply slot.
