Minimum Software Requirements; Power Supply Cords For Ac Power Supplies - Extreme Networks BlackDiamond 8806 Hardware Installation Manual

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:
●
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.
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

The Extreme Networks PSUs have the following minimum software requirements:
600/900 W AC PSU
●
For the system to recognize a 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.
700/1200 W AC PSU
●
The 700/1200 W AC PSU is supported by all versions of ExtremeXOS software.
1200 W DC PSU
●
For the system to recognize the 1200 W DC PSU, the MSM in your BlackDiamond 8800 series switch
must be running ExtremeXOS version 11.3 or later.

Power Supply Cords for AC Power Supplies

The AC PSUs used with the BlackDiamond 8800 series switches can use either 110 V AC or 220 V AC
power supply cords. Table 19
when used with each AC power supply.
Power supply cords are not shipped with the AC PSUs. To purchase an AC power cord, contact your
local Extreme Networks Channel Account Manager or Sales Manager, or purchase a cord from your
local supplier. The power cord must meet the requirements listed in
page 172.
