Cisco Systems, Inc. WS-C3850-48XS-E Ethernet Switch

The Cisco WS-C3850-48XS-E is a 1U standalone Catalyst 3850 switch featuring 48 SFP+ ports and 4 QSFP+ uplinks, designed for fixed deployments that demand high‑density 10 Gb/s access and scalable 40 Gb/s core connectivity. Each SFP+ port supports 10G Ethernet, delivering substantial downlink capacity across the 48 ports, while the four QSFP+ uplinks provide high‑bandwidth aggregation to a campus or data‑center core when paired with appropriate transceivers. The unit is powered by a front‑to‑back 750 W AC power supply and occupies a standard 19‑inch rack space, making it straightforward to integrate into existing racks. It runs IP Services feature set, enabling advanced routing, QoS, security, and management features, and it is not StackWise‑480 stackable, so it cannot be combined with other 3850s for a single logical stack. This model is intended for standalone use or as part of a larger network topology where high‑speed access ports are required at the distribution edge or in data‑center leaf roles, with the flexibility to configure uplinks as 40G or multiple 10G links depending on transceiver choices.
