Safety Precautions

Precautions

Read this manual, in its entirety, prior to installing the device.
Observe all warnings and cautions mentioned in this manual.
Keep the device dry, ventilated, and clean.
During severe weather conditions, unplug all electrical connections to the device to protect against lightning surges.
Keep the ventilation openings clean to ensure proper airflow and prolong the life of the device. Do not place objects on the device that might block airflow and lead to overheating.
ONTs should not be opened. There are no user-serviceable parts in the device.

Laser Safety

Warning 1! Personnel handling fiber optic cables must be trained for laser safety.

Warning 2! Optical Fibers emit invisible laser radiation. Avoid direct exposure to the beam. Never look into the end of a Fiber or into a Fiber connector on a cable or a device. Permanent eye damage or blindness can occur quickly from laser radiation.

Fiber Optic Cable

Ensure that the fiber connectors are properly cleaned per local standards. Dirty connectors may result in inaccurate measurements.

Caution 1: Fiber optic cable installation and maintenance should only be performed by trained service personnel.

Caution 2: Do not bend the fiber optic cable to a diameter smaller than 7.5cm/3 inches. Doing so may damage the fiber or prevent the signal from passing through properly.

Electrical Safety

Warning! Do not open the enclosure unless directed to do so by Tellabs technical support. Doing so is dangerous and voids the warranty.

Check that the DC power supply polarity is correct. The system will not be damaged by reversed polarity but will not operate until the polarity is corrected.
Do not install electrical equipment in wet or damp conditions.
Ensure that the power source for the system is adequately rated to assure safe operation and provides current overload protection.
Do not allow anything to rest on the power cable, and do not place this product where people can stand or walk on the power cable.

Electrostatic Discharge (ESD)

Observe and follow all ESD instructions while handling Tellabs plug-in equipment.

Caution! The Tellabs plug-in equipment uses semiconductor devices that can be damaged by electrostatic discharge (ESD). Do not remove a plug-in from a protective packing box or equipment rack until the time of installation or replacement. To equalize the static charge on the plug-in, establish a body path to the ground using an ESD wrist strap connected to an ESD ground. [If storing or shipping the plug-in becomes necessary, place the plug-in in a conductive shipping box to prevent static buildup.]

Apply the following precautions:

Use grounded wrist straps, table mats, floor mats
Handle static-sensitive devices in the nonconductive areas
Place static-sensitive cards into an antistatic plastic bag
Use protective ESD-sensitive packing and shipping bags when returning repairable components

Product Disposal

The Waste Electrical and Electronic Equipment (WEEE) symbol (shown below) will accompany products that must be collected and disposed of separately from household waste. The black bar under the symbol signifies the product was placed on the market after August 13, 2005.
