S5720I-SI Series Switches with Extended-Temperature Switch
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. As such, they can be widely used in access scenarios such as Ethernet to the x (ETTx).
Extended Operating Temperature Range
Temperature range of -40°C to +75°C adapts to a wide range of ambient temperature changes.
Advanced PoE++
60W PoE++ achieves 200m long-distance power supply along with applicable Huawei video security cameras.
Maintenance-Free Lifecycle
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).
