Printed circuit board components and Programmable Read-only
Memory (PROM) devices can be damaged during routine handling
and installation. Follow these precautions to reduce static electricity
discharges before you upgrade the processor firmware.

Handle the printed circuit boards and PROMs by the case or
carrier without touching the pins or the edge connector.

Use a static-free workstation.

Connect the static-free workstation to ground through a minimum
200K ohm resistance.

Wear a grounded, conductive wrist strap with a minimum 200K
ohm resistance.

Ground all tools before you begin to upgrade the firmware.

Control the relative humidity of the installation area – ideal
conditions are 40% to 60% relative humidity.
