Cisco WS-X45-SUP7L-E=

Overview

The Cisco WS-X45-SUP7L-E= is a supervisor engine designed to upgrade Catalyst 4500E chassis, providing the performance and visibility required by modern enterprise networks. It delivers a total switching capacity of 520 Gbps and allocates 48 Gbps of dedicated bandwidth to each slot, ensuring line cards operate without contention even during traffic surges. This module supports high packet forwarding rates, handling up to 225 million IPv4 packets and 110 million IPv6 packets per second, making it well suited for environments with growing device counts and dual-stack applications.

Equipped with 2 GB of SDRAM and 1 GB of flash memory, it can store large routing tables and feature-rich IOS software. Features like Non-Stop Forwarding and Stateful Switchover maintain network uptime during maintenance or failover events. Cisco EnergyWise integration helps monitor and reduce power consumption, supporting energy-efficient network operations.

Connectivity and compatibility

This supervisor engine integrates seamlessly into Catalyst 4500E chassis, supporting a wide range of line cards and network modules. Its compliance with IEEE 802 standards ensures compatibility with existing Ethernet networks and VLAN configurations. The module’s high forwarding rates and large routing table capacity make it suitable for complex Layer 3 routing environments in enterprise campuses, hospitals, and universities.

Performance and reliability

Designed to maintain network stability, the module’s Non-Stop Forwarding and Stateful Switchover features allow uninterrupted data forwarding during software upgrades or hardware failovers. This resilience is critical for mission-critical environments where downtime is not an option. The dedicated bandwidth per slot prevents performance degradation during traffic spikes, ensuring consistent throughput across all connected devices.

Ideal uses and environments

This supervisor engine fits well in enterprise networks requiring advanced routing and traffic analysis without replacing existing Catalyst 4500E infrastructure. It is a strong choice for organizations that need detailed flow analytics, robust Layer 3 routing, and energy monitoring capabilities. Whether deployed in a core network with redundancy or a cost-conscious wiring closet, it balances throughput, operational insight, and reliability to support growing network demands.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
