WS-C4503 Cisco Catalyst 4503 3-Port Supervisor Engine Switch Chassis Network Switch

Cisco Catalyst 4503 WS-C4503

Cisco's WS-C4503 chassis provides the modular foundation for distribution and core roles in medium and large enterprise networks. It is part of the Catalyst 4500 Series, running Cisco IOS.

A modular design lets you mix interface modules for copper, fiber and high-speed uplinks, and add capacity as needs grow. Confirm which modules, power supplies and fans are included with this part number when planning your build. Modular chassis are a familiar choice for core and distribution roles. A chassis protects your investment by letting you upgrade modules over time. Modular platforms usually offer redundant power and management options for high-availability designs.

In the aggregation layer it brings together traffic from access switches and connects it to servers and the WAN. High-capacity links and routing at this layer help the network scale cleanly. The WS-C4503 part number makes it easy to source identical units for future expansion. A capable aggregation layer keeps performance consistent as demand rises. This Cisco model is a strong foundation for redundant network designs with multiple uplinks and failover paths. Add the Cisco WS-C4503 to your network for modular chassis switching you can depend on.
