Board Replacement Preliminaries

14.1.1

ESD Requirements

Electronic components on printed circuit boards are extremely sensitive to
static electricity. Normal amounts of static electricity generated by clothing
can damage electronic equipment. To reduce the risk of damage due to
electrostatic discharge when installing or servicing electronic equipment, use
anti-static earthing straps and mats.
Before removing or replacing boards from the chassis, take these
2 steps:
1. Locate the ESD (electrostatic discharge) connections on the Avaya G860 Media
Gateway chassis. Refer to the diagrams in 'Front and Back Views of the Avaya
G860 Media Gateway' on page 14.
2. Attach a wrist strap for electrostatic discharge (ESD) and connect it to an ESD
connection on the chassis using a banana plug or an alligator clip.
Note:
Before starting any replacement procedure, be sure to prepare all
replacement components and tools to be used in advance.
Electrical Component Sensitivity
Do not set components down without first protecting them with an anti-
static bag.
