EX4300-48MP Juniper

ll the devices in the rack and provide options for optimized airflow (hot aisle/cold aisle). Three variants of the EX4300 switches are available—24-port, 32-port, and 48-port switches, with or without PoE+, with AC or DC power supplies, and with different airflow directions. EX4300 switches also provide uplink ports and a slot for installing an optional uplink module. You can manage EX4300 switches except the Multigigabit switches EX4300-48MP and EX4300-48MP-S by using the same interfaces that you use for managing other devices running Juniper Networks Junos operating system (Junos OS)—the CLI, the J-Web graphical interface, and Junos Space. You can manage the Multigigabit switches EX4300-48MP and EX4300-48MP-S by using the the CLI.Software Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks M Series, MX Series, and T Series routers, and SRX Series Services Gateways.EX4300 Switches First View EX4300 switches provide connectivity for high-density Gigabit Ethernet data center top-of-rack, enterprise, and campus aggregation/core deployments. EX4300 switches can be used in large branch offices, campus wiring closets, and data centers. In data centers, these switches can be positioned as the top devices in a rack to provide connectivity for all devices in the rack and provide options for optimized airflow (hot aisle/cold aisle). The 48-port EX4300 switches EX4300-48T and EX4300-48P provide 48 built-in 10/100/1000BASE-T Ethernet network ports, with or without PoE+ depending on the switch model, and four built-in quad small form-factor pluggable plus (QSFP+) ports that can house 40-Gigabit QSFP+ transceivers. All network ports in the EX4300-48P switch are equipped for Power over Ethernet (PoE+), whereas EX4300-48T has no PoE+ ports. These switches support AC or DC power supply with different airflow directions. Each switch provides a slot for installing an optional 4-port 10-Gigabit Ethernet SFP+ uplink module, which has four SFP+ ports that can house four SFP+ transceivers, four SFP transceivers, or a combination of four SFP+ and SFP transceivers. The 48-port EX4300 switches with multigigabit ports—EX4300-48MP and EX4300-48MP-S—provide 24 built-in 10/100/1000BASE-T Ethernet network ports, 24 built-in 100/1000/2500/5000/10000BASE-T Ethernet network ports, and four built-in 40-Gigabit Ethernet quad small form-factor pluggable plus (QSFP+) ports that can house 40-Gigabit QSFP+ transceivers. The 24 built-in 10/100/1000BASE-T Ethernet network ports support 10 Mbps, 100 Mbps, and 1 Gbps speeds. The 24 built-in 100/1000/2500/5000/10000BASE-T Ethernet network ports support 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps speeds. All network ports are equipped for PoE+ and provide up to 95 watts of power. The QSFP+ ports are configured as Virtual Chassis Ports (VCPs) by default. You can use them to connect the switches to other devices in a Virtual Chassis configuration. These switches support AC power supply with front-to-back airflow. Each switch provides a slot for installing an optional 4-port 10GbE uplink module. The 4-port 10GbE uplink module can house four SFP+ transceivers. - Dual redundant, load-sharing power supplies that are hot-insertable and hot-removable field-replaceable units (FRUs) - Two fan modules that are field-replaceable units - Redundant Routing Engines in a Virtual Chassis or QFX5100 Virtual Chassis Fabric (VCF) configuration. This redundancy enables graceful Routing Engine switchover (GRES) - Junos OS with its modular design that enables failed system processes to gracefully restart
