NOTE
Extreme Networks does not recommended using the 1200 W DC PSU in combination with any Extreme Networks
AC PSU in the same BlackDiamond 8800 series system. Extreme Networks recommends that DC and AC PSU units
not be used together in the same BlackDiamond switch.
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.
WARNING!
Field operators must not attempt to open the 1200 W DC PSU enclosure for any reason; the PSU does not contain
user-serviceable parts. In the event of failure, return the defective 1200 W DC PSU to Extreme Networks for repair
or replacement.
Minimum Software Required
The MSM installed in your BlackDiamond 8800 series switch must be running ExtremeXOS version 11.3
or later for the system to recognize the DC PSU.
