Advanced Surge Protection Technique
The S3300 uses the Huawei patented built-in surge protection technique. This technique protects
devices against lightning in terrible weather and increases device security.
Convenient PoE Power Supply
The S3300 has the Power over Ethernet (PoE) function. It provides centralized power supply
for IP phones, wireless access points (APs), portable device chargers, POS machines, cameras,
and data collectors by using twisted pairs.
Complying with IEEE 802.3af and IEEE 802.3at, the PoE-enabled S3300 is able to remotely
provide power for the devices of different vendors. IEEE 802.3at delivers a maximum of 30 W
power. This allows IEEE 802.3at to support IP video phones, dualband WiFi APs, IP cameras,
multi-function STBs, and RFIDs, and simplifies the network.
The S3300 has the ability to control power supply based on time range, which effectively
manages network devices, reduces power consumption, and lowers the OPEX.
