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