MAINTENANCE

Precautions

Electromagnetic fields radiating from the system cabinets may generate noise in other communications equipment. The technician must be sure that all cabinet panels and covers are securely in place after performing maintenance.

Caution: Electrostatic discharge can destroy or severely damage integrated circuits on CPs.

The maintenance technician MUST ALWAYS WEAR A WRIST GROUNDING STRAP when handling CPs. The cord must be attached to the grounding block at the back of the cabinet. Damage to integrated circuits caused by electrostatic discharge may not be immediately apparent.

Caution: The wrist grounding strap must not be clipped to any cabinet location other than the grounding block or a front-cover retainer screw. The wrist grounding strap must not be attached to a CP.
