Compliance and Safety Information

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

Laser Safety

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:

Warning 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.

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.

Note 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 Figure 2-1. 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.
