IEEE 802.3at, defined PoE+. An IEEE 802.3af powered device operates normally when
connected to an IEEE 802.3at (PoE+) power sourcing equipment.
EX4200 switches with an AC power supply installed have options of full (all 24 or 48
ports) PoE/PoE+ capability or partial (8 ports) PoE capability. EX4200 switches with a
DC power supplyinstalled do not providePoE. For more information,see “EX4200 Switch
Models” on page 5.
Full PoE/PoE+ models are primarily used in IP telephony environments. Partial PoE
models are used in environments where, for example, only a few ports for wireless access
points or security cameras are required.

EX4200 Switch Models
The EX4200 switch is available with 24 or 48 ports and with partial or full Power over
Ethernet (PoE) capability. EX4200 switches with a DC power supply installed do not
provide PoE.
NOTE: This topic uses the term PoE to refer to both PoE and PoE+ unless
there is a need to distinguish between the two.
Table 3 on page 5 lists the EX4200 switch models.
