15 Replacing a BlackDiamond 8800 Series/
BlackDiamond 12804 PSU/Fan Controller
This chapter describes important safety information as well as instructions on how to remove and
replace an Extreme Networks BlackDiamond 8800/12804 PSU/fan controller from the following
BlackDiamond switches:
Extreme Networks BlackDiamond 8800 series of switches
●
Extreme Networks BlackDiamond 12804 switch
●
Each of these BlackDiamond switches contains two PSU/fan controllers that collect and report data
from the Extreme Networks AC power supply units and the BlackDiamond fan tray.
The BlackDiamond 8800/12804 PSU/fan controllers intervene in the event of power inconsistencies and
provide primary/backup redundancy should a BlackDiamond 8800/12804 PSU/fan controller fail.
NOTE
The BlackDiamond 8810 uses the same PSU/fan controller as the BlackDiamond 8806 and BlackDiamond 12804,
but the BlackDiamond 8810 uses a different fan tray.
