NOTE
For central DC power connections, the 1200 W DC PSU and 325 W DC PSU are intended to be installed only in a
restricted access location (for example, a dedicated equipment room, equipment closet, or central office) 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.
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.
Overview of BlackDiamond 12800 Series Power
Supplies
The BlackDiamond 12800 series switches can be powered by either AC or DC power supplies (PSUs).
Power supplies in the BlackDiamond 12800 series switches are fully fault tolerant and load-sharing in
an N+1 configuration. After the system is properly configured, if one PSU fails, the others will provide
sufficient power to operate a fully loaded switch.
The BlackDiamond power supply units are intended for use in specific BlackDiamond switches only.
Table 9 lists the power supplies for use in the BlackDiamond 12800 series switches.
