Cisco 4503 - Catalyst Switch Administrator Guide

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.
Select the 1400W supply for Cisco Catalyst 4510R

Quick Power Calculations
Calculating the maximum power required is simple.
Your total system power requirement comes from two
sources: data and PoE plus some efficiency loss. The
following chart gives you baseline power requirement
numbers for data power components on the Cisco
Catalyst 4500E.

At-A-Glance

Cisco Catalyst 4503 + Supervisor Engine IV + 2x
10/100/1000 PoE = 304W Data Power (96 x class 3 PDs) /
89% = 1661W PoE Power
Total Power required = 1661W + 304W = 1965W

Multi-Input Supplies Explained
Dual-Input 4200wac
The 4200W power supply is designed to accept either
a 100V or a 200VAC circuit. Customers planning large-
scale PoE deployments can use the inputs in the 200V
mode. Customers planning for the future can deploy the
4200W supply with as little as one 100V circuit.

1400WDC-P Power Input Options
The 1400WDC-P power supply has two operating
modes. The default data-only mode and the inline power
mode. When inline power is selected, the supply can
provide up to 8600W of power to the chassis (data and
PoE). This is enough power to support a fully loaded
Cisco Catalyst 4510 with all class 3 devices. This power
can come from a variety of sources, including the AC
power shelf or an AC-powered DC UPS.
An AC-powered DC UPS is powered by standard com-
mercial power and outputs -48VDC to the 1400WDC-P
supply. When compared with a standard AC UPS this
solution is more efficient, produces less heat, takes
up less space, and provides longer run times than a
standard AC UPS. The AC-powered DC UPS requires
only a single AC/DC conversion compared to three in
an AC UPS.
