configure power supply
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
ExtremeWare XOS 11.5 Command Reference Guide
117
For all other combinations of 220V AC and 110V AC PSUs, ExtremeWare XOS maximizes system power
by enabling all PSUs and budgeting each PSU at 110V AC.
In addition to the PSU, you can specify the following options:
●
auto
—Specifies that ExtremeWare XOS determines the enabled or disabled state of the PSU to
maximize total system power. This is the default.
●
on
—Specifies that the PSU be enabled even if ExtremeWare XOS determines it should be disabled.
This action may reduce the total available system power and may result in one or more I/O modules
powering down.
You can override automatic power supply management to enable a PSU with 110V AC inputs that
ExtremeWare XOS disables if the need arises, such as for a planned maintenance of 220V AC circuits. If
the combination of AC inputs represents one of those listed in
Table 10
, you can turn on a disabled PSU
using the
configure power supply
<ps_num> on
command.
NOTE
If you override automatic power supply management, you may reduce the available power and cause one or more I/O
modules to power down.
To resume using automatic power supply management on a PSU, use the
configure power supply
<ps_num> auto
command. The setting for each PSU is stored as part of the switch configuration.
To display power supply status and power budget information use the
show power
and
show power
budget
commands.
Example
The following command configures the PSU in slot 1 to be forced on when either 110V AC or 220V AC
power input is present, overriding automatic power management:
configure power supply 1 on
The switch displays the following message:
In a mixed environment of 110V and 220V AC inputs, power management may
automatically disable 110V supplies to maximize the system power budget.
By specifying 'on', you wish to override power management and enable the
specified power supply. This may cause the system power budget to decrease
and one or more I/O cards may be powered off as a result.
