Port 1-8 of the switch support Power over Ethernet (Po E) function. These Po E ports can automatically detect & supply power with those IEEE 802.3af/at compliant Powered Devices (PDs). When total power consumption excels 63W, the intelligent power management will cut the lower priority port power off to ensure the high priority port's power supply & protect the device from power overload operation. Sturdy, compact metal casing, with desktop/wall-mounting design, to meet your needs in any environment. Besides, fanless design ensures quiet operation.
