Juniper EX 4200 48-Port 10/100/1000BASE-T with 24 PoE Ports, 930W AC Power Supply Unit and 50cm Virtual

The EX 4200 series Ethernet switches support internal redundant, load-sharing, hot-swappable and field-replaceable AC and DC power supplies to maintain uninterrupted operations Includes a hot-swappable, field-replaceable fan tray with three blowers, providing sufficient cooling even if one of the blowers were to fail To avoid the complexities of the Spanning Tree Protocol (STP) without sacrificing network resiliency, the EX 4200 series switches employ redundant trunk groups to provide the necessary port redundancy and simplify switch configuration Cross-member link aggregation allows redundant link aggregation connections between devices in a single virtual-chassis configuration, providing an additional level of reliability and availability The EX 4200 series switches leverage a purpose-built packet forwarding engine ASIC, the EX-PFE, which integrates much of the same intellectual property used in Juniper Networks carrier routers
