Cisco Catalyst 4900 Series Switches

The Cisco Catalyst 4900 Series is a family of high-performance, fixed-configuration switches designed specifically for space-constrained top-of-the-rack server aggregation. These switches deliver line-rate Layer 2-4 switching with exceptionally low latency, making them ideal for modern Data Center environments.

The series includes the compact Catalyst 4948 (1RU) and the versatile, semi-modular Catalyst 4900M (2RU). Both models provide enterprise-class availability features, including 1+1 redundant, hot-swappable internal AC or DC power supplies and field-replaceable fan trays. Built on the proven architecture of the Catalyst 4500, these switches offer robust security features and advanced Quality of Service (QoS) without compromising throughput, ensuring reliable connectivity for mission-critical servers and high-speed storage arrays.
