The Cisco XR 12410 router are designed to meet the regulatory compliance and
safety approval requirements. Refer to the Regulatory Compliance and Safety
Information for Cisco 12000 Series Routers
Single-mode Cisco XR 12410 router line cards are equipped with lasers. The
lasers emit invisible radiation. Do not stare into open line card ports. Observe the
following warning to prevent eye injury:
Avoid exposure to laser radiation. Do not stare into an open aperture, because
invisible laser radiation may be emitted from the aperture when a cable is not
inserted in the port.
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.
Before you perform any of the procedures in this guide, attach an ESD-preventive
strap to your wrist and connect the leash to the chassis as shown in
Note that some versions of the 10-slot chassis do not provide an ESD connection
socket in the line card cage area. For those chassis, use an alligator clip to connect
the leash to an open metal part of the chassis.
