PoE-capable port with up to 15.4 W in compliance with the IEEE 802.3af PoE standard.
lists the power supply ratings, and the associated PoE power budgets for EX4200 switch models that
support PoE.
Starting with Junos OS Release 11.1, EX4200 switches support enhanced PoE, a Juniper Networks extension
to the IEEE 802.3af PoE standard. Enhanced PoE permits up to 18.6 W per PoE port. Because the power
supply provided with a switch is designed to supply a maximum of 15.4 W per PoE port, if you connect a
powered device that draws more than 15.4 W, the PoE power budget might not be sufficient to supply a
full 15.4 W to the remaining PoE ports.
NOTE: Switches upgraded to Junos OS Release 11.1 from a previous release require a separate
upgrade of the PoE controller software to enable enhanced PoE support.
EX4200-24PX and EX4200-48PX switches support PoE+, the IEEE 802.3at PoE standard, and permit up
to 30 W per port.
