Power-Over-Ethernet - Motorola EX-3524 Installation Manual

preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure
that it complies with the IEEE 802.3-2008 standards.

3.4.4 Power-over-Ethernet

The switch supports both IEEE 802.3af and IEEE 802.3at-2009 PoE standards that enable DC power to be supplied
from the switch's RJ-45 copper ports to connected devices by utilizing certain pairs of the connecting Ethernet
cable.
For the EX-3524, the total PoE power delivered by all ports cannot exceed the 390 W power budget. This means up
to 12 ports can supply a maximum 30 W of power simultaneously to connected devices, or all 24 ports can supply
a maximum of 15.4 W.
For the EX-3548, the total PoE power delivered by all ports cannot exceed the 779 W power budget. This means up
to 24 ports can supply a maximum 30 W of power simultaneously to connected devices, or all 48 ports can supply
a maximum of 15.4 W simultaneously.
Any PoE-compliant device attached to a port can directly draw power from the switch over the Ethernet cable
without requiring its own separate power source. This capability gives network administrators centralized power
control for devices such as IP phones and wireless access points, which translates into greater network availability.
To connect 100BASE-T cables to RJ-45 ports:
1. Consider network and cabling requirements to select an appropriate transceiver type that is also
compatible with the switch transceiver support.
2. Attach the other end to an available port on the switch. Ensure each twisted pair cable does not exceed
100 meters (328 ft) in length.
3. As each connection is made, the Link LED (on the switch) corresponding to each port will turn on green to
indicate that the connection is valid.
