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.
