Safety and Compliance
Laser Safety
Single-mode Cisco XR 12000 series 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.
Lifting Guidelines
A fully configured Cisco XR 12406 Router weighs approximately 205 pounds (93
kg). Before you install the router, ensure that your site is properly prepar ed so that
you will not have to move the router later to accommodate power source a nd/or
network connections.
Caution To prevent damage, never attempt to lift or tilt the router chassis using the handles
on the blower module or line cards. These handles do not support the weight of
the chassis.
Whenever you lift any heavy or awkward equipment, follow these precautions to
avoid injury to yourself or damage to the equipment:
•When using moving equipment, such as a safety hand truck, pallet jack, or
forklift to move the equipment to another location, use only moving
equipment that is capable of preventing the router from tipping .
•Have a second person help lift the equipment; avoid lifting the equipment
alone.
•Ensure that your footing is solid; balance the weight of the object between
your feet.
•Lift the equipment slowly; never move suddenly or twist your body as you
lift.
