Warnings and Cautions

Before removing the node access panel, be sure that you understand the following warnings and
cautions.
WARNING!
To reduce the risk of electric shock or damage to the equipment:
• Do not disable the AC power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
