Safety Recommendations

Safety Recommendations

The following information is included to alert you to safety recommendations and best practices when working with this equipment.

Maintaining Safety with Electricity

Follow these guidelines when working on equipment powered by electricity.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

General Safety Practices

Follow these guidelines to ensure personal safety and protect the equipment:

Keep the chassis area clear and dust-free during and after installation.

Put the removed chassis cover in a safe place.

Keep tools away from walk areas where you and others could fall over them.

Do not wear loose clothing that could get caught in the chassis.

Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.

Warning This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The telecommunications lines must be disconnected 1) before unplugging the main power connector or 2) while the housing is open, or both. Statement 1043

Safety Tips

Use these tips as safety guidelines when installing or working around this equipment.

Locate the emergency power-off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power.

Disconnect all power before installing or removing a chassis.

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.
