Preinstallation Requirements and Planning for Cisco 2800 Series Routers
OL-5784-01
  General Site Requirements
Preventing Electrostatic Discharge Damage 
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if 
electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. 
Always follow ESD prevention procedures when removing and replacing modules:
Ensure that the router chassis is electrically connected to earth ground. 
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to 
an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To 
guard against ESD damage and shocks, the wrist strap and cord must operate effectively. 
If no wrist strap is available, ground yourself by touching a metal part of the chassis. 
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:
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 [AC-powered systems only], current draw, and power dissipation for 
the unit.)
