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.
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 inlet indicates
the correct voltage frequency, current draw, and power dissipation for the unit.)
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
section “
,” to help avoid equipment failures and reduce the possibility of
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:
•
Ensure that the room where your router operates has adequate air circulation. Electrical equipment
generates heat. Without adequate air circulation, ambient air temperature may not cool equipment
to acceptable operating temperatures.
•
Always follow ESD-prevention procedures described in the
“Preventing Electrostatic Discharge
to avoid damage to equipment. Damage from static discharge can
cause immediate or intermittent equipment failure.
