Energy Hazard
The Cisco ASR 9001 Router can be configured for a DC power source. Do not touch terminals while they
are live. Observe this warning to prevent injury.
Hazardous voltage or energy may be present on power terminals. Always replace cover when terminals
are not in service. Be sure uninsulated conductors are not accessible when cover is in place. Statement

Warning
Preventing Electrostatic Discharge Damage
Many router components can be damaged by static electricity. Not exercising the proper electrostatic discharge
(ESD) precautions can result in intermittent or complete component failures. To minimize the potential for
ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes
good skin contact.
Check the resistance value of the ESD-preventive strap periodically. The measurement should be between
1 and 10 megohms.
Note
Before you perform any procedure in this guide, attach an ESD-preventive strap to your wrist and connect
the leash to the chassis as shown in the figure below.
