CAUTION
The 700/1200 W AC PSU does not have a switch for turning the unit on and off. Remove the plug from the
electrical outlet to disconnect power to the 700/1200 W AC PSU. Make sure that this connection is easily
accessible.
●
Make sure that the 700/1200 W AC PSU circuit is not overloaded. Use proper over-current protection, such as a
circuit-breaker, to prevent over-current conditions.
Extreme Networks 600/900 W AC PSU
This section describes important safety information, specifications, and correct procedures for installing
and removing an Extreme Networks

600/900 W AC UL Listed Accessory power supply unit
(Model # 41050/PS 2431) into and out of the following UL Listed BlackDiamond

8806 switch
Extreme Networks 600/900 W AC PSUs are fully fault tolerant and load-sharing in an N+1
configuration. After the system is properly configured, should one Extreme Networks 600/900 W AC
PSU fail, the others will provide sufficient power to operate a fully loaded switch. The power supply
bay can accommodate up to six hot-swappable Extreme Networks 600/900 W AC PSUs. See the
ExtremeXOS Concepts Guide for information on configuring your Extreme Networks BlackDiamond 8806
switch.
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 (see
Figure 89 ). Airflow enters from the front vents of the PSU and
exits to the rear vents of the switch. Airflow through the PSU is independent of the airflow through the
rest of the switch.
CAUTION
To ensure proper cooling of the PSU, do not block the front vents of the Extreme Networks 600/900 W AC PSU or
the rear vents of the switch.
