CAUTION
Even though this process avoids the possibility of over-current, an I/O module may be powered off if a 600/900 W
AC PSU is added to a BlackDiamond 8806 system running in the following configuration:
AC PSU is added to a BlackDiamond 8806 system running in the following configuration:
●
The system is powered by three 700/1200 W AC PSUs at 220 V AC.
●
The system includes four or more PoE I/O modules with a PoE power requirement that falls between 2391 W
and 2438 W of inline power.
and 2438 W of inline power.
To avoid causing an I/O module to be powered off, do not add a 600/900 W AC PSU to an existing
BlackDiamond 8806 system running in the configuration listed above. Extreme Networks also
recommends that you avoid mixing 220 V AC and 110 V AC inputs when both 600/900 W and
700/1200 W PSUs are present in the same system. When a combination of 220 V AC and 110 V AC
inputs is applied, ExtremeXOS is designed to optimize total chassis power for each individual PSU type
but not for a mixture of PSU types.

NOTE
Extreme Networks does not recommended using the 1200 W DC PSU in combination with any Extreme Networks
AC PSU in the same BlackDiamond 8800 series system. Extreme Networks recommends that DC and AC PSU units
not be used together in the same BlackDiamond switch.

Minimum Software Requirements
In order for the system to recognize an Extreme Networks 600/900 W AC PSU, the MSM installed in
your BlackDiamond 8806 switch requires ExtremeXOS version 11.6.1 (or later). In ExtremeXOS releases
11.3.4, 11.4.2, and 11.5.1, the 600/900 W AC PSU is disabled on all chassis. In ExtremeXOS releases
earlier than those, the software does not recognize the 600/900 W AC PSU and the PSU will not be
budgeted properly, possibly resulting in PSU shutdown and/or chassis reboot.
