NOTE: You cannot form a Virtual Chassis by using SFP transceivers.
For forming a Virtual Chassis, you must explicitly configure an uplink port on each of the switches to be
connected as a VCP. See Setting an Uplink Port on an EX Series or QFX Series Switch as a Virtual
Chassis Port.
For information about the supported optical and copper interfaces, see "Pluggable Transceivers
Supported on EX2300 Switches" on page 75.
Console Ports
EX2300 switches except the EX2300-24MP and EX2300-48MP switch models have two console ports
—an RJ-45 console port and a Mini-USB Type-B console port. EX2300-24MP and EX2300-48MP switch
models have an RJ-45 console port. The RJ-45 port accepts a cable that has an RJ-45 connector and the
Mini-USB Type-B port accepts a Mini-B plug (5-pin) connector to connect the switch to a console
management device.
Cable Guard
On an EX2300-C switch, 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 "Mounting an EX2300 Switch on a
Desk or Other Level Surface" on page 106, "Mounting an EX2300-C Switch Under a Desk or Other Level
Surface by Using Screws" on page 108, and "Mounting an EX2300-C Switch on or Under a Surface
Made of Ferrous Material" on page 127.
Security Slot
An EX2300-C switch has a security slot on the right panel of the chassis. You can use the security slot to
lock and secure the chassis in the installation site with a standard cable lock. See "Mounting an EX2300
Switch on a Desk or Other Level Surface" on page 106, "Mounting an EX2300-C Switch Under a Desk or
Other Level Surface by Using Screws" on page 108, and "Mounting an EX2300-C Switch on or Under a
Surface Made of Ferrous Material" on page 127.
Power over Ethernet (PoE) Ports
EX2300 switches are available with or without PoE/PoE+ capability. Models that support PoE/PoE+
provide that support on all RJ-45 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. Uplink ports do not support PoE.
