Chapter 2 Preparing to Install the Router

General Site Requirements

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:

•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 2-1describes power requirements for Cisco 2600 series routers.

Table 2-1 Power Requirements for Cisco 2600 Series Routers

		Input Voltage
Power Source	Input Power	Tolerance Limits
AC	100 - 240 VAC, 1.0 A, 50 - 60 Hz	85	- 264 VAC
DC	48 - 60 VDC, 3.0 A	38	- 72 VDC

Site Environment

The router can be placed on a desktop or mounted in a rack. Single rack-unit (1RU) routers can also be mounted on a wall. The location of the chassis and the layout of your equipment rack or wiring room are extremely important for proper system operation. Placing equipment too close together, inadequate ventilation, and inaccessible panels can make system maintenance difficult or cause system malfunctions and shutdowns.

When planning your site layout and equipment locations, remember the precautions described in the next section, “Site Configuration,” to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or unusually high errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.
