EX2300 switches provide:
Up to four 10-Gigabit Ethernet uplink ports that support small form-factor pluggable
plus (SFP+) transceivers and small form-factor pluggable (SFP) transceivers.
12 (in EX2300-C switches), 24, or 48built-in Gigabit Ethernet RJ-45 network ports with
10/100/1000 BASE-T connectors.
Virtual Chassis capability—You can connect up to four EX2300 switches (including
EX2300-C switches) to form one unit that you manage as a single chassis, called a
Virtual Chassis.
Power over Ethernet (PoE) or Power over Ethernet Plus (PoE+) on all RJ-45 network
ports (in PoE-capable models).
EX2300-C switches have two 10-Gigabit Ethernet uplink ports that support SFP and
SFP+ transceivers. EX2300 switches except the EX2300-C switch model have four
10-Gigabit Ethernet uplink ports that support SFP and SFP+ transceivers. You can use
these uplink ports as network ports or configure these ports as Virtual Chassis ports
(VCPs) and use them to connect up to four switches by using SFP+ transceivers to form
a Virtual Chassis.
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 Switch as
a Virtual Chassis Port (CLI Procedure).
For information about the supported optical and copper interfaces, see
Transceivers Supported on EX2300 Switches" on page
EX2300 switches have two console ports—an RJ-45 console port and a Mini-USB Type-B
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. The switch activates only one console port at a
time—either the RJ-45 console port or the Mini USB Type-B console port. By default, the
RJ-45 port is the active console port and the Mini-USB Type-B port is the passive console
port. You can change the default setting of a console port by using the
command. See Configuring the Console Port Type (CLI Procedure).
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 129, "Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using
