Chapter 1 Product Overview

System Architecture

All PoE switching modules can distinguish an IEEE or Cisco prestandard powered device from an unpowered network interface card (NIC) to ensure power is applied only when an appropriate device is connected. With a Cisco PoE network, administrators can depend on a robust network that is safe to deploy and simple to maintain.

Deploying PoE on the Cisco Catalyst 4500 E-series

When the switch is properly configured, implementing PoE is easy when it is used with a Cisco powered device that supports Cisco Discovery Protocol. All PoE switching modules automatically detect an attached powered device the moment it is installed. Also, the switch returns unused port power to the system power budget for use by other devices because it supports the IEEE802.3af optional power classifications.

The Cisco Catalyst 4500 E-series offers internal power supplies and external power devices for multiple deployment scenarios. These scenarios include small and large deployments in AC or DC environments for data-only configurations, and scalability of up to 15.4 W per port for PoE configurations.

The switches share a common power supply form factor. Each Cisco Catalyst 4500 E-series chassis is designed for 1 + 1 power protection while meeting the needs of PoE demands. In addition to power resiliency, the Cisco Catalyst 4500 E-series includes 1 + 1 supervisor-engine redundancy (Cisco Catalyst 4507R-E and Catalyst 4510R-E only) and software-based fault tolerance. Integrated resiliency in both hardware and software minimizes network downtime, helping ensure workforce productivity, portability, and customer success.

All available Cisco Catalyst 4500 E-series compatible power supplies can be used for data-only deployments, which typically require just a few hundred watts. For deployments that dictate support for PoE power, Cisco offers several options.

The Cisco Catalyst 4500 E-series offers several internal supplies: 1000 W AC (data only), 1400 W AC (data only), 1300 W (data and PoE), 1400 W DC (data and PoE), 2800 W (data and PoE), and 4200 W AC (data and PoE). When more than 4200 W of redundant data and PoE are required for a Cisco Catalyst 4500 E-series chassis in an AC-powered environment, Cisco offers an external AC power shelf that houses two 2500 W AC power supplies. When two power shelves are combined, they can produce 7500 W—the remaining 2500 W supply can be used for N + 1 protection.

The Cisco Catalyst 4500 E-series has two DC power options; one is optimized for data-only deployments in service provider central offices (part number PWR-C45-1400DC), and the other is used for high-power PoE deployments (part number PWR-C45-1400DC-P).

Cisco Catalyst 4500 Series External AC Power Shelf and

1400 W DC Power Supply with Integrated Power Entry Module

The external AC power shelf must be used in conjunction with the 1400 W DC power supply. In addition to providing power for the chassis, fans, and non-PoE switching modules, the 1400 W DC power supply contains a power entry module (PEM). The PEM is used to pass additional power to the chassis backplane, power demanded by the PoE switching modules. The chassis power trace used for PoE is independent from the one used by the supervisor engine(s), fan tray, and backplane components. The 1400 W DC power supply can accept up to 7500 W DC for data and PoE applications. Up to 1400 W can be dedicated for data (supervisor engine, fan tray, etc.), while the remaining power is passed through via the PEM and is used for PoE.

When only one external AC power shelf is used (with two 2500 W AC power supplies), it provides the 1400 W DC power supply with 5000 W of DC power in total. When two AC power shelves are strapped together, the switch can provide up to 7500 W of DC power (3 + 1 redundant).
