Functions of the PAC1K2S12-PF
Functions
Description
Input overvoltage protection and undervoltage protection
In this protection state, the power module stops supplying power. When the input voltage restores to the normal range, the power module automatically resumes power supply.
Input overcurrent protection
In this protection state, the power module stops supplying power and cannot automatically resume power supply when the input current restores to the normal range.
Output overvoltage protection
In this protection state, the power adapter stops supplying power intermittently. When the output voltage restores to the normal range, the power adapter automatically resumes power supply.
Output overcurrent protection
In this protection state, the power module supplies power intermittently. When the output current is limited within a range, the power module automatically resumes power supply.
Output short-circuit protection
In this protection state, the power module supplies power intermittently. When the short circuit is removed, the power module automatically resumes power supply.
Overtemperature protection
When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.
Heat dissipation
Back-to-front airflow
Hot swapping
The power module is hot swappable.

PAC1K2S12-PF FAQ
Q1: Which optical modules does this switch support? What is its transmission distance coverage?
A1: It supports the full range of 400GE optical modules (short-distance 100m - long-distance 40km), compatible with Huawei and industry standard optical modules, adaptable to different transmission scenarios such as within data centers and across campuses, with 100% adaptability.
Q2: Can the 1U chassis meet the heat dissipation requirements of 32 400G ports? How does the redundancy design ensure reliability?
A2: A 5+1 redundant fan + port-side air intake cooling design can quickly dissipate heat under high load; 1+1 power supply redundancy, 5+1 fan redundancy, MTBF up to 26.01 years, single module failure does not affect services, maximizing reliability.
Q3: Compared to similar 400G switches, what are its core advantages?
A3: Its core advantages are "ultra-dense + high performance + compact". It boasts an industry-leading density of 32 400GE ports, a space-saving 1U design, and a 16-core CPU to support high-load forwarding, resulting in a comprehensive deployment cost reduction of over 30%.
