Chapter 2 Preparing to Install the Router
General Site Requirements
Caution For the safety of your equipment, periodically check the resistance value of the antistatic strap. It should
be between 1 and 10 megohms (Mohm).
General Site Requirements
This section describes the requirements your site must meet for safe installation and operation of your
router. Ensure that the site is properly prepared before beginning installation. If you are experiencing
shutdowns or unusually high errors with your existing equipment, this section can also help you isolate
the cause of failures and prevent future problems.
Power Supply Considerations
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.
Warning The device is designed for connection to TN and IT power systems. Statement 1007
The AC power supply includes the following features:
• It 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 cord indicates
the correct voltage, frequency, current draw, and power dissipation for the unit.)
Table 2-1 lists power requirements for Cisco 3700 series routers.
