2. Official Product Overview

The Cisco Catalyst WS-C4500X-32SFP+ is a high-density fixed-form-factor 1RU 10 Gigabit aggregation switch belonging to the Catalyst 4500-X series, released 2012, End-of-Sale October 30, 2020, End-of-Support October 31, 2025Cisco. It is a compact high-port-density aggregation platform designed as a cost-effective fixed alternative to large modular Catalyst 4500 chassis, optimized for space-limited high-density wiring closets, multi-floor building distribution, medium campus core, and enterprise data center leaf/spine deployments requiring massive 10GE fiber port capacity.

The base unit ships without power supplies; hot-swappable AC/DC redundant power supplies and optional uplink expansion modules are sold separately as FRUs (Field Replaceable Units). It features 32 built-in dual-speed SFP+ ports supporting 1G SFP or 10G SFP+ transceivers, plus one rear modular expansion slot for the optional C4KX-NM-8SFP+ 8-port 10GE uplink module to extend total port density up to 40×10GE ports, delivering significantly higher base port count than the 16-port WS-C4500X-16SFP+ variantCisco.

Running modular Cisco IOS XE software, it delivers full wire-speed Layer 2 switching and hardware-accelerated Layer 3 IPv4/IPv6 routing, hierarchical MQC QoS, comprehensive enterprise security suite, Flexible NetFlow traffic monitoring, and VSS multi-chassis virtual switching to pair two WS-C4500X switches into a single logical redundant core device. All critical FRUs (power supplies, fan trays) support live hot-swap replacement without full chassis shutdown to maximize network uptime for mission-critical traffic.
