The Cisco Catalyst 4500 Series has two DC power options—one is optimized for data-only deployments in service provider central offices (part
number PWR-C45-1400DC), the other is used for high-power PoE deployments (part number PWR-C45-1400DC-P).
CISCO CATALYST 4500 SERIES EXTERNAL AC POWER SHELF AND 1400W DC POWER SUPPLY WITH INTEGRATED POWER
ENTRY MODULE
The Cisco Catalyst 4500 Series external AC power shelf must be used in conjunction with the 1400 WDC 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-
through additional power 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 via 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 in total. 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 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. Low current inputs mean 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 two 20A and one 15A circuits rather than a single 60A
connection, which often requires rack rewiring (Table 3).
