Safety
Only trained service personnel should perform service to Extreme Networks switches and their
components. Trained service personnel have read all related installation manuals, have the technical
training and experience necessary to be aware of the hazards to which they are exposed in performing a
task, and are aware of measures to minimize the danger to themselves or other persons.
NOTE
See Appendix A, “Safety Information” for additional safety information and Appendix B, “Technical Specifications”
for additional information regarding regulatory compliance certifications.
CAUTION
Be sure that proper ESD controls are in use before switch maintenance is performed. This includes but is not
limited to wrist straps that are grounded to the switch chassis and earth grounds.
CAUTION
The EPS must be installed or removed only by trained service personnel in accordance with the installation
instructions. Before installing or removing any components of the system, or before carrying out any maintenance
procedures, read the safety information provided in Appendix A of this guide. Not following these precautions can
result in equipment damage or shock.
WARNING!
Extreme Networks AC PSUs do not have switches for turning the unit on and off. Remove the wall plug from the
electrical outlet to disconnect the power to an Extreme Networks AC PSU. Make sure that this connection is easily
accessible.
