Extreme Networks 700/1200 W AC PSU
Figure 24 shows the Extreme Networks 700/1200 W AC UL-listed accessory power supply unit
(Model # 60020/PS 2336). The power supply bay in a BlackDiamond 8800 series switch can
accommodate up to six hot-swappable Extreme Networks 700/1200 W AC PSUs.
Figure 24: Extreme Networks 700/1200 W AC PSU
The front panel on each Extreme Networks 700/1200 W AC PSU contains two cooling fans and a handle
for insertion and removal of the unit. Airflow enters the front vents on the PSU and exits through the
rear vents of the switch. Airflow through the Extreme Networks 700/1200 W AC PSU is independent
from the airflow through the rest of the switch.
The AC input connection is located on the switch directly below each installed power supply.
NOTE
In a BlackDiamond 8806 system, the Extreme Networks 700W/1200 W AC PSU can be used with an Extreme
Networks 600/900 W AC PSU in the same chassis.
Extreme Networks does not recommended using the 700/1200 W AC PSU with an Extreme Networks 1200W DC
PSU in the same BlackDiamond 8800 series switch.
WARNING!
Field operators must not attempt to open the 700/1200 W AC PSU enclosure for any reason; the PSU does not
contain user-serviceable parts. In the event of failure, return the defective 700/1200 W AC PSU to Extreme
Networks for repair or replacement.
LEDs
The front panel of the Extreme Networks 700/1200 W AC PSU provides status LEDs. Table 9 describes
the LED activity.
