Product Review

The Cisco WS-C4503-E chassis offers flexibility in power supply options, supporting a wide range of AC and DC inputs, catering to diverse operational needs. However, it lacks supervisor engine redundancy, which could be a critical drawback for environments requiring high availability. With support for up to 48 Gbps bandwidth scalability per line card slot, it is capable of meeting the demands of high-throughput networking tasks, though its limitation to just three slots may restrict expansion capabilities.


The Cisco WS-C4503-E is a versatile chassis designed for the Catalyst 4500 series switches, offering a compact yet powerful platform for enterprise-level networking. This chassis is tailored to support a range of applications, including high-performance Ethernet switching, routing, and integrated Power over Ethernet (PoE). With its dimensions measuring 12.25 inches in height, 17.31 inches in width, and 12.5 inches in depth, the chassis occupies 7 rack units (RU) and weighs 32.25 lbs, making it suitable for both 19-inch and 23-inch rack installations. Key to the WS-C4503-E's design is its capacity to host up to 3 slots, including 2 line card slots and a dedicated slot for a supervisor engine. The chassis supports a variety of supervisor engines, including models 8-E, 8L-E, 7-E, 7L-E, 6-E, and 6L-E, but does not offer supervisor engine redundancy. Each line card slot can scale up to 48 Gbps of bandwidth, ensuring efficient data handling and transfer speeds required for demanding network environments.
  • Integrated PoE capabilities allow for up to 1500 W of power per slot, facilitating the direct supply of operational power to PoE-enabled devices.
  • AC and DC power input options ensure flexibility in power sourcing, with AC power supplies ranging from 1000W to 9000W ACV, and DC power supplies available in 1400W configurations.
  • The chassis includes 1 fan tray bay, ensuring effective cooling for the installed hardware components.
Mounting options for the chassis are designed to be flexible, accommodating both 19-inch and 23-inch rack mounting in the front location. This feature allows for easy integration into a wide variety of networking environments and simplifies the installation process. Power supply support is extensive, with the WS-C4503-E compatible with multiple AC power supplies, including 1000W AC, 1400W AC, 1300W ACV, 2800W ACV, 4200W ACV, 6000W ACV, and 9000W ACV options. For environments requiring DC power, the chassis supports 1400W DC (Triple Input) and 1400W-DC-P power supplies, offering the versatility needed for different operational requirements. The Cisco WS-C4503-E chassis is engineered to meet the needs of medium to large-sized network deployments. Its support for high-performance supervisor engines and line cards, combined with flexible power options and efficient cooling, make it a suitable foundation for building a resilient, high-capacity network infrastructure.
