of PoE demands. In addition to power resiliency, the Cisco Catalyst 4500 Series includes 1 + 1
supervisor-engine redundancy (Cisco Catalyst 4507R-E/4507R and 4510R-E/4510R models only)
and software-based fault tolerance. Integrated resiliency in both hardware and software minimizes
network downtime, helping ensure workforce productivity, profitability, and customer success.
Table 1 gives an overview of IEEE 802.3af power classifications.

Comparison Between Cisco Prestandard PoE and 802.3af-Compliant PoE
From a power perspective, there are several significant differences between the Cisco prestandard
and 802.3af-compliant line cards. The differences are illustrated by comparing the total number of
PoE devices supported by the Cisco prestandard inline power line card and the 802.3 af-compliant
line cards (Table 2).

Cisco Catalyst 4500 E-Series Power-Supply Options: AC and DC
The Cisco Catalyst 4500 E-Series offers a variety of power supplies and accessories to meet the
diverse needs of enterprise and service provider customers. All available Cisco Catalyst 4500
Series 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 AC power with several internal supplies: 1000W (data
only), 1400W (data only), 1300W (data and PoE), 2800W (data and PoE), 4200W (data and PoE),
and 6000W (data and PoE). When 5500W or less are required, the 4200W power supply can
provide 5500W while protecting the chassis from a power or power-supply sub-unit failure. When
