EX4600 Ethernet Switches offer a compact, highly scalable, high-performance solution for enterprise campus distribution deployments as well as low-density data center top-of-rack environments. Designed to help organizations grow into higher density campuses, the EX4600 provides deployment flexibility, high availability using unified in-service software upgrades (unified ISSU), and management simplification. The EX4600 also supports Juniper's Virtual Chassis technology, which allows interconnected switches to operate as a single, logical device.
