S5720I-SI Series Switches with Extended Temperature Range
Huawei S5720I-SI series are standard Layer 3 gigabit switches that provide flexible all-gigabit access and cost-effective fixed GE ports and 10 GE uplink ports. They support an industry-grade temperature range and have strong outdoor surge protection to withstand harsh outdoor cabinet environments. They can be widely used in Safe City and ETTx access scenarios.
Extended Operating Temperature Range
Temperature range of -40°C to +75°C adapts to a wide range of ambient temperature changes.
60W PoE++ achieves 200m long-distance power supply along with applicable Huawei surveillance cameras.
Built-in dual power supplies and redundant fans ensure full-lifecycle, maintenance-free design (only some models support this feature, for details see the data sheet).
