5: Troubleshooting Information
Handling NAS Internal Components
Caution:
Electrostatic discharge (ESD) can damage electrostatic-sensitive devices inside the
NAS enclosure. Use the ESD precautions described below when you handle printed circuit boards
or other components in the system. The following measures are generally sufficient:
•
Use a grounded wrist strap designed to prevent electrostatic discharge.
•
Touch a grounded metal object before removing any board from its antistatic bag.
•
Handle each printed circuit board (PCB) by the edges; do not touch the components,
peripheral chips, memory modules, or gold contacts on the PCB.
•
When handling any device with exposed chips or modules, avoid touching the pins.
•
Place the NAS head node board, drives, or other boards and components into antistatic bags
when not in use.
•
Make sure your system chassis provides a conductive path between the power supply, the
case, the mounting fasteners, and the node board to chassis ground.
Detecting Component Failures
Use the information in the following subsections to determine if any errors are occurring in the
drives or system power supplies.
