To reduce the risk of equipment damage, the Sonus SBC 1000/2000 system should be kept in an electrostatic discharge (ESD) protected environment. The unit should be properly grounded at all times. The Sonus SBC 1000/2000 chassis should be plugged in and its grounding lug should be connected. When performing routine maintenance on the unit, a wrist strap should be plugged into the ESD jack located on the rear of the chassis.

Prevention of ESD Damage

To prevent ESD damage observe the following precautions:

• Wear an ESD grounding strap connected to a proper ground when handling modules.
• Keep boards in their antistatic protection bags until you are ready to install them.
• Do not touch pins, leads, or solder connections on the boards.
• Handle modules only by their edges, ejector handles, or stiffener rails.
• Store and ship modules in antistatic protection packaging.
