Power over Ethernet (PoE) Ports
EX2200 switches are available in models with or without PoE/PoE+ capability. Models
that support PoE/PoE+ provide that support on all network ports. PoE ports provide
electrical current to devices—such as IP phones, wireless access points, and security
cameras—through network cables, thus eliminating the need for separate power cords
for those devices.
EX2200 switches with DC power supply do not provide PoE.
EX2200 switches running Junos OS Release 10.3 or later support powered devices that
comply with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+).
NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher
Ethernet cables.
EX2200 switches running Junos OS Release 10.2 or earlier support powered devices that
comply with IEEE 802.3af (PoE).
The remainder of this topic uses the term PoE to refer to both PoE and PoE+ unless there
is a need to distinguish between the two.
Front Panel of an EX2200 Switch
The front panel of an EX2200 switch except the EX2200-C switch models consists of
the following components:
•
Network ports—depending on the switch model, either of:
•
24 or 48 10/100/1000BASE-T Gigabit Ethernet ports, with Power over Ethernet
(PoE) not available in EX2200-24T, EX2200-24T-DC, and EX2200-48T
•
24 or 48 10/100/1000BASE-T Gigabit Ethernet ports, with Power over Ethernet
(PoE) available in EX2200-24P and EX2200-48P
•
4 built-in SFP uplink ports
•
2 chassis status LEDs
•
4 port status mode LEDs
•
Mode button

ports. Figure 2 on page 6 shows the front panel of an EX2200 switch with 24 Gigabit
Ethernet ports.
