If you lose power or the overall available power decreases, the system removes power to the
I/O modules beginning with the highest numbered slots until enough power is available. Inline
power reserved for a slot that is not used cannot be used by other PoE slots (inline power is
not shared among PoE modules).

Power Delivery
This section describes how the system provides power to the PDs.
Enabling PoE to the Switch
You enable or disable inline power to the entire switch, or per slot or per port.
If you are working on a NETGEAR 8800 switch chassis, you must reserve power for each
PoE slot. By default, 50 watts of inline power is provided to each slot. (See
PoE slot. By default, 50 watts of inline power is provided to each slot. (See
on page 174 for information on reserving power on these devices.)
To enable inline power to the switch, slot, or port, use the following commands:
enable inline-power
To disable inline power to the switch, use the following command:
disable inline-power
Disabling inline power removes power immediately to all connected PDs. The default value is
enabled.
enabled.
Power Reserve Budget
On modular switches, the power budget is provided on a per slot basis, not switchwide. You
reserve power for each slot, or PoE module. Power reserved for a specific PoE module
cannot be used by any other slot regardless of how much power is actually consumed on the
specified slot. The default power budget reserved for each PoE module is 50 W. The
minimum power you can assign to a slot is 37 W, or 0 W if the slot is disabled. The maximum
possible for each slot is 768 W.

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 or switch 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 or
switch (for example, when delivered power from ports increases or when the configured inline
power budget for the slot is reduced).
