Enabling Inline Power; Reserving Power For A Slot - Extreme Networks ExtremeWare XOS Guide Manual

NOTE
If your chassis has an inline power module and there is not enough power to supply a slot, that slot will not power
on; the slot will not function in data-only mode without enough power for inline power.
To configure inline power, or PoE, you must accomplish the following tasks:
Enable inline power to the system, slot, and/or port.
●
Reserve power to the PoE slot, using a power budget.
●
Configure the disconnect precedence for the PDs in the case of excessive power demands.
●
Configure the threshold for initiating system alarms on power usage.
●
Additionally, you can configure the switch to use legacy PDs, apply specified PoE limits to ports, apply
labels to PoE ports, and configure the switch to allow you to reset a PD without losing its power
allocation.

Enabling Inline Power

You enable inline power to the switch, slot, or port using the following commands:
enable inline-power
enable inline-power slot <slot>
enable inline-power ports [all | <port_list>]
NOTE
If your chassis has an inline power module and there is not enough power to supply a slot, that slot will not power
on; the slot will not function in data-only mode without enough power for inline power.
To disable inline power to the switch, slot, or port, use the following commands:
disable inline-power
disable inline-power slot <slot>
disable inline-power ports [all | <port_list>]
Disabling the inline power to a PD immediately removes power from the PD.
To display the configuration for inline power, use the following command:
show inline-power

Reserving Power for a Slot

You reserve power for a given slot. The power reserved for a given slot cannot be used by any other
PoE slots, even if the assigned power is not entirely used.
To reallocate power among the slots, you must reconfigure each slot for the power budget you want; the
power is not dynamically reallocated among PoE modules. You do not have to disable the PoE modules
to reconfigure the power budgets.
