Chapter 2 Installing the Cisco 7201 Router
Connecting Power
Note After powering off the router, wait a minimum of 30 seconds before powering it on again.
If required, use Sinewave Output UPS (uninterruptable power supply), not Ferro-resonant type UPS.
This completes the procedure for connecting AC-input power. Your installation is complete. Proceed to
Chapter 3, “Starting and Configuring the Router,” to start the router and to perform a basic configuration.
Connecting DC-Input Power
This section provides instructions for installing the DC power supply ground leads and installing the
DC-input power leads.
Figure 2-22 Power Supply Slot 1 and Slot 2
The Cisco 7201 has two of the same type of power supplies in power supply slot 1 and power supply
slot 2. See Figure 2-22. The power supply slot numbers are on the chassis to the left of the left power
supply, and to the right of the right power supply.
Warning
Never install an AC power module and a DC power module in the same chassis.
Statement 1050
Caution Before you connect DC-input power, you must install the DC power ground leads to the DC power
supply.

When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
