and electric power for powered devices such as VoIP telephones, wireless access points,
and IP security cameras that require 12.95 W or less. The remaining 16 ports provide only
network connectivity. You use the standard ports to connect devices that have their own
power sources, such as desktop and laptop computers, printers, and servers. Table 440
on page 3308 details the topology used in this configuration example.
