How To Select A Power Supply For Cisco Catalyst 4500
E-Series Switches
Getting Started
Questions to ask when selecting a power supply.
Is Power Over Ethernet (Poe) Required?
If PoE is not required, select the 1000W supply for the
Cisco
Catalyst
4503, 4506, and 4507R Switch chassis.

4200W AC Power Supply
1000WAC: Data-only AC power supply designed for
Cisco Catalyst 4503, 4506, and 4507R chassis
1300WACV: Data and limited PoE up to 46 class 3
devices; designed for small IP telephony and wireless
deployments
1400WAC: Data-only AC supply designed for Cisco
Catalyst 4510R chassis
2800WACV: Data and PoE up to 80 class 3 devices;
designed for medium-sized PoE deployments
1400WDC-P: Data and large-scale PoE or DC PoE
deployments; designed to be used with -48VDC power
sources such as the power shelf or an AC-powered
DC UPS
1400WDC: Data-only DC supply; designed for service
providers with low-current circuits
4200WACV: Data and large-scale PoE deployments;
designed for large PoE deployments
Quick Power Calculations

Calculating the maximum power required is simple.
Your total system power requirement comes from two
