more than 5500W of redundant data and PoE are required for a Cisco Catalyst 4500 Series
chassis in an AC-powered environment, Cisco offers an external AC power shelf that houses two
2500-WAC power supplies. When two power shelves are combined, they can produce 7500W—
the remaining 2500W supply can be used for N + 1 protection. All Cisco Catalyst 4500 AC power
supplies are single phase.
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 (PWR-C45-1400DC-P).
Cisco Catalyst 4500 E-Series External AC Power Shelf and 1400-WDC Power Supply
with Integrated Power Entry Module
The Cisco Catalyst 4500 E-Series external AC power shelf must be used in conjunction with the
1400-WDC-P power supply. In addition to providing power for the chassis, fans, and non-PoE line
cards, the 1400-WDC power supply contains a power entry module (PEM). The PEM is used to
pass additional power through to the chassis backplane, power demanded by the PoE line cards.
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-WDC power supply can accept up to
7500 WDC for data and PoE applications. Up to 1400W can be dedicated for data (supervisor[s],
fan tray, etc.), while the remaining power is passed through the PEM and is used for PoE.
When only one external AC power shelf is used (with two 2500-WAC power supplies), it provides
the 1400-WDC power supply with 5000W of DC power. When two AC power shelves are strapped
together, the Cisco Catalyst 4500 Series can provide up to 7500W of DC power (3 + 1 redundant).
Cisco Catalyst 4500 E-Series Service Provider DC Power Supply
The triple-input 1400-WDC power supply is optimized for service provider central-office
deployments. By providing multiple inputs, the service provider DC power supply allows central-
office technicians to customize the output power to meet their application needs. Many central-
office deployments require only a fraction of the 1400W available in the service provider power
supply. With low-current inputs, technicians can connect the supply to smaller fuses and breakers.
The service provider power supply makes it possible to deploy a Cisco Catalyst 4503 with a single
15A circuit. Likewise, it is possible to deploy a fully populated Cisco Catalyst 4510R with one 15A
and two 20A circuits rather than a single 60A connection, which often requires rack rewiring (Table 3).

Cisco Catalyst 4500 E-Series Dual Input AC PoE Power Supplies
The 6000W ACV and 4200W ACV power supplies feature combined Mode Power Resiliency as an
extension of the traditional combined mode power-supply behavior. Each power supply contains
two smaller power supplies (called sub-units). In Combined Mode Power Resiliency the system
relies only on power from three out of four power-supply sub-units. When using 200 VAC, this
