Cisco Catalyst 6500 Series Switch WS-C6504E-ACE20-K9 Overview
Cisco Catalyst 6500 Series Switch WS-C6504E-ACE20-K9 is a genuine core and distribution switching product from Cisco, a leading enterprise networking vendor whose Catalyst, Nexus and ISR families power campus, data-center and branch networks worldwide. Belonging to the Cisco Catalyst 6500 Series family, the WS-C6504E-ACE20-K9 unit is built to the original factory specification, so it integrates with existing Cisco deployments predictably and behaves exactly as the platform documentation describes. In the network, it is positioned for campus core and distribution roles, aggregating traffic for large user populations with resilient failover behavior.
This unit follows the original factory specification for the Cisco Catalyst 6500 Series family, covering its intended role without compatibility surprises. Standard mounting, cabling and management practices apply, and it interoperates with surrounding hardware using the same procedures as other Cisco equipment already deployed in the network.
Typical deployments include access-layer deployments for user, phone and AP connectivity, distribution and core aggregation in campus networks, and top-of-rack and end-of-row switching in data centers. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “ACE20 4G 6504E Bundle”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
