Power Guidelines and Requirements
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 AC power supply includes the following features:
• Autoselects either 110 V or 220 V operation.
• All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power inlet indicates
the correct voltage, frequency [AC-powered systems only], current draw, and power dissipation for
the unit.)
Table 2-3 lists power requirements for the Cisco ISR 4451-Xs.
