PoE Management
In traditional networking, all terminal devices are applying power supply directly via power
lines, leading to high expenses and complicated cabling work.
Power over Ethernet or PoE describes any of several standardized or ad-hoc systems
which pass electrical power along with data on Ethernet cabling. It not only ensures
normal network operation, but greatly reduces expenses. PoE allows cable as long as
100m. This allows a single cable to provide both data connection and electrical power to
devices such as network hubs, IP cameras, wireless APs and closed-circuit TV cameras,
etc. The IEEE standard for PoE requires category 5 cable or higher for high power levels,
but can operate with category 3 cable if less power is required.
8 10/100/1000M auto-negotiation RJ45 ports of this switch are IEEE 802.3af, IEEE
802.3at PoE capable, which allows it to connect to up to 8 IEEE 802.3 af PDs or 4 IEEE
802.3at PDs. The PoE power supply mode is dynamic, i.e. the switch accommodates
power supply for powered devices automatically. Pair 1, 2 and pair 3, 6 are applying PoE
power supply and Ethernet specifications limit the cable length between the switch and
the attached device to 100 m (328 ft).
