ExtremeWare XOS 11.5 Command Reference Guide
510
configure inline-power budget slot
configure inline-power budget <num_watts> slot <slot>
Description
Sets the reserved power on the specified slot to the specified watts on modular switches.
Syntax Description
Default
50 W.
Usage Guidelines
This command sets the budgeted power reserved for all PDs connected to the specified slot in Watts.
None of the power budget on a specified slot can be used to power other slots or PDs on other slots.
You can modify the power budget without disabling the slot.
If you specify a slot that is not configured to hold a PoE module, the system returns the following error
message:
Error: Slot 2 is not capable of inline-power.
If the power consumption of the PDs on a specified slot exceeds this configured power budget, the
system disconnects the lowest priority ports. (Refer to
configure inline-power priority ports
for
information on configuring this parameter.)
If you attempt to configure this power budget for a value that the system cannot safely provide, the
system returns an error message. To display inline power settings, use the command
show inline-power
;
to display the power for the entire switch, use the command
show power budget
.
NOTE
You must disable inline power for a slot using the
disable inline-power slot
command prior to setting the budget to
0.
To reduce the chances of ports fluctuating between powered and non-powered states, newly inserted
PDs are not powered when the actual delivered power for the module is within approximately 19 W of
the configured inline power budget for that slot. However, actual aggregate power can be delivered up
to the configured inline power budget for the slot (for example, when delivered power from ports
increases or when the configured inline power budget for the slot is reduced).
num_watts
Specifies the number of watts to reserve for specified slot for inline power. Enter
an integer. The minimum value is 37, or 0 if the slot is disabled; the maximum
is 768; and the default value is 50.
slot
Specifies a slot. The slot must be configured to hold a PoE module.
