On an EX2200-C switch model, you can install a cable guard to secure the cables
connected to the switch. The cable guard has slots in the front of it through which you
can pass all the cables to prevent them from being accidently unplugged or removed
after they are connected. See
Surface" on page 119.
Each EX2200-C switch model has security slots on the left and right panels of the chassis.
Use the security slots to lock and secure the chassis in the installation site with a standard
cable lock . See "Mounting an EX2200 Switch on a Desk or Other Level Surface" on
page 119.
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.
NOTE: Starting with Junos OS Release 12.2R1, PoE commands are enabled
on all non-PoE-capable EX2200 switch models. The PoE commands do not
provide any meaningful information on standalone non-PoE-capable switch
models. However, in an EX2200 Virtual Chassis, you can execute PoE
commands from a non-PoE-capable switch that is the master, to configure
PoE on PoE-capable Virtual Chassis members.
PoE-capable 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.
