Chapter3 Installing the CiscoAS5350 Supplying Power
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.
Note The redundant power supply is supported in CiscoIOS Release 12.2(2)XB5 or later releases.
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 fa ctor correction, and
low Total Harmonic Distortion. Power failures are reported through environmental monitoring software.
Check the power at your site to e nsure that you are receiving “clean” power (free of spikes and nois e).
Install a power conditioner if necessary.
The universal gateway AC power supply includes the following features:
•Full range operation—100 to 240 VAC.
•All AC units include a 6-foot (1.8 -m ete r) electrical power cord (A label near the power i nl ets
indicates the correct vol tage, frequency, current draw, and power d is s i pa tion for the unit.)
Note The redundant AC power supply has a n on-standard connector. Use the electrical power co rd that
came with your universal gateway.
The universal gateway DC power supply includes the following features:
•150 W output
•Dual input connections for power source redundancy
•Removable DC connector (A label near the power inlets indicates the correct voltage, cu rrent draw,
and power dissipation f or t he unit.)
•Double-hole grounding lug for reliable grounding to the chassis
Follow this procedure to co nn ec t p owe r to the universal gateway:
Step 1 Connect one end of the AC power cord to the power connector on the rear panel of the Cisco AS5350 (See
Figure3-17 or Figure 3-18.) Or, if you are usin g a DC -powered unit, refer to Figure3-19 or Figure3-20,
and complete Step a through Step e.
Step 2 Connect the other end of the AC power cord to the power outlet.
Warning
This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that
a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the
phase conductors (all current-carrying conductors). To see translations of the warnings that appear
in the publication, refer to the Regulatory Compliance and Safety Information document that
accompanied this device.
Warning
The device is designed to work with TN power systems. To see translations of the warnings that appear in
the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this
