Supplying Power - Cisco AS5350 Installation Manual

Chapter 3 Installing the Cisco AS5350

Supplying Power

The power system comprises an AC or DC power supply or a redundant AC or DC power supply, with
internal cooling provided by two self-contained fans.
The redundant power supply is supported in Cisco IOS Release 12.2(2)XB5 or later releases.
Note
Each power module is capable of supplying a maximum DC load of 150 watts, and is composed of four
independent output voltages: 3.3V, 5V, 12V, and -12V. AC input units have power factor correction, and
low Total Harmonic Distortion. Power failures are reported through environmental monitoring software.
Check the power at your site to ensure that you are receiving "clean" power (free of spikes and noise).
Install a power conditioner if necessary.
The universal gateway AC power supply includes the following features:

Follow this procedure to connect power to the universal gateway:
Connect one end of the AC power cord to the power connector on the rear panel of the Cisco AS5350 (See
Step 1
Figure 3-17 or Figure 3-18.) Or, if you are using a DC-powered unit, refer to Figure 3-19 or Figure 3-20,
and complete Step a through Step e.
Connect the other end of the AC power cord to the power outlet.

All AC units include a 6-foot (1.8-meter) electrical power cord (A label near the power inlets
indicates the correct voltage, frequency, current draw, and power dissipation for the unit.)
The redundant AC power supply has a non-standard connector. Use the electrical power cord that
came with your universal gateway.
