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.
Before installing an Extreme Networks PSU into your network:
● Read the latest installation and safety information provided in this chapter and in Appendix
A, “Safety Information.”
● See Appendix A, “Safety Information” for additional information regarding regulatory compliance
certifications.
NOTE
For central DC power connections, the 1200 W DC PSU is intended to be installed only in restricted access
locations (dedicated equipment rooms, equipment closets, or the like) in accordance with Articles 110-16, 110-17,
and 110-18 of the National Electric Code, ANSI/NFPA-70. All wiring methods involving the DC input cable assembly
must be performed according to the relevant articles of the National Electrical Code.
CAUTION
Building codes vary worldwide; therefore, Extreme Networks strongly recommends that you consult an electrical
contractor to ensure proper equipment grounding and power distribution for your specific installation.
WARNING!
Field operators must not attempt to open the PSU enclosure for any reason; the PSU does not contain
user-serviceable parts. In the event of failure, return the defective PSU to Extreme Networks for repair or
replacement.
