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 Cisco IOS 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 po wer factor correction, and
low Total Harmonic Distortion. P ower failures are reported through environmental monitoring software.
Check the power at you r s ite to e nsure that you are rece ivin g “cl ean” power (free of spikes and noise).
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- f oot (1.8-meter) electrical pow er co r d (A l ab el ne ar t he pow er i nl ets
indicates the c or r e ct vol tage, frequency, curre nt d raw, an d pow er dissipation for t he unit.)
Note The redundant AC power su pply has a non-standard con nector. 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 in dicates the correct voltage, curr ent draw,
and power dissi pa tio n for the unit.)
•Double-hole grounding lug for reliable grounding to the chassis
Follow this procedur e t o connect power to the un iversa l gateway:
Step 1 Connect one end of the AC power cord to the power connector on the rear panel of the Cisco AS5350 (See
Figure 3-17 or Figure3-18.) Or, if you are using a DC-po w ere d uni t, refe r to Fi gur e3-19 or Figure 3-20,
and complete Step a thro u gh Ste p 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
