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.
The AC power supply includes the following features:

Site Environment
Cisco IAD2801 series integrated access devices can be placed on a desktop or installed in a rack. The
location of your router and the layout of your equipment rack or wiring room are extremely important
considerations for proper operation. Equipment placed too close together, inadequate ventilation, and
inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for
access to both front and rear panels of the router.
When planning your site layout and equipment locations, remember the precautions described in the next

environmentally caused shutdowns. If you are currently experiencing shutdowns or an unusually high
number of errors with your existing equipment, these precautions may help you isolate the cause of the
failures and prevent future problems.
Site Configuration
The following precautions will help you plan an acceptable operating environment for your router and
will help you avoid environmentally caused equipment failures:
