Beschreibung
Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the enterprise market, including branch offices, campus locations, and data centers. The Juniper Networks EX2300 Ethernet Switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services.
Uplink Ports
EX2300-C switches have two 10-Gigabit Ethernet uplink ports that support SFP and SFP+ transceivers. EX2300 switches except the EX2300-C switch model and the EX2300-48MP switch model have four 10-Gigabit Ethernet uplink ports that support SFP and SFP+ transceivers. EX2300-48MP switch model has six 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.
Console Ports
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.
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, Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws, and Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material.
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, Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws, and Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material.
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.
