S5720I-SI Switch Ingress Protection Rating
Short answer
C The S5720I-SI switch supports IP66 ingress protection for harsh outdoor environments.
Question
Key Takeaways
This question tests knowledge of specific hardware environmental ratings. The main trap is confusing IP66 (powerful jets) with IP65 (low pressure jets) or IP67 (immersion).
The S5720I-SI industrial switch supports IP66 rating. Learn why this is the correct answer for Huawei H19-301 exam questions regarding outdoor network equipment specifications.
Common mistake: Candidates often choose IP65 because they associate 'outdoor' with general weatherproofing rather than the specific high-pressure jet requirement. Others may incorrectly select IP67, assuming all industrial switches are submersible.
Expert Analysis
The S5720I-SI is a specific industrial-grade switch designed for harsh environments, and its ingress protection rating is defined by Huawei's official datasheet. The question asks specifically which IP standard the device supports.
According to Huawei's product documentation (e.g., EDOC1000013597), the S5720I-SI features an IP66 rated front panel. This rating ensures that the device is protected against powerful water jets from any direction, making it suitable for outdoor installations where heavy rain or washing down might occur. It is not IP67 rated, as IP67 implies temporary immersion in water, which is not the primary design goal for this specific RJ45-port-based switch model in this context; rather, it focuses on high-pressure jet resistance.
While some community comments suggest IP65 or IP67 based on misinterpretations of 'industrial' vs 'outdoor', the official specification clearly lists IP66. Therefore, Option C is the correct answer.

Exam Strategy
When studying for datacom hardware exams, memorize the specific environmental ratings (IP, temperature range) for key enterprise switch models like the S5700 series. Do not assume all 'industrial' switches share the same IP code; distinguish between jet resistance (IP66) and immersion (IP67).

dvd93 👍 1 Answered CIP67 means immersion in water up to 1 meter deep for 30 minutes, connector is RJ45 not for submerge. so this reference is make sense https://support.huawei.com/enterprise/en/doc/EDOC1000013597/182e4b14/s5720i-6x-pwh-si-ac
