Extreme Networks 600/900 W AC PSU
Figure 25 shows the Extreme Networks 600/900 W AC UL-listed accessory power supply unit (Model #

supply bay can accommodate up to six hot-swappable Extreme Networks 600/900 W AC PSUs.
Figure 25: Extreme Networks 600/900 W AC PSU
The front panel on each Extreme Networks 600/900 W AC PSU contains two cooling fans and a handle
for insertion and removal of the unit. Airflow enters the front vents of the PSU and exits through the
rear vents of the switch. Airflow through the PSU is independent of the airflow through the rest of the
switch.
The AC input is located on the switch directly below each installed power supply.
NOTE
The Extreme Networks 600/900 W AC PSU can be used in combination with an Extreme Networks 700W/1200W
AC PSU in the same BlackDiamond 8806 system.
Extreme Networks does not recommend using the 600W/900W AC PSU in combination with an Extreme Networks
1200W DC PSU in the same BlackDiamond 8806 system.

Networks for repair or replacement.
