Juniper Networks EX4300 Ethernet Switches provide connecvity for high-density environments and
scalability for growing networks. These switches can be deployed wherever you need high density of
Gigabit Ethernet ports or redundancy. Typically, EX4300 switches are used in large branch oces,
campus wiring closets, and data centers. In data centers, EX4300 switches can be posioned as top-of-
rack switches; the top devices in a rack to provide connecvity for all the devices in the rack and provide
opons for opmized airow (hot aisle/cold aisle).
