Configuring the Total Power Available to a Slot
Like the maximum port power allowance, the system software also provides a maximum slot-wide power
allowance. By default, each slot is authorized by the system software to use a number of watts to power
all devices connected to its ports depending on which power supply is used.
As with the maximum port power allowance, the user can either increase or decrease this value based
on the allowed ranges.
Note. Decreasing the slot-wide power could cause lower priority ports to lose
power if the new value is less than the total PoE power currently being
consumed.
To increase or decrease the total power available to a slot, use the lanpower slot maxpower command.
Since you are setting the power allowance for an individual slot, you must specify a chassis/slot value in
the command line. For example, the syntax
-> lanpower slot 3/1 maxpower 400
reduces the power allowance of chassis 3, slot 1 to 400 watts. This value is now the maximum amount of
power the slot can use to power all attached devices (until the value is modified by the user).
Note. Changing the maximum power available to a slot or port does not reserve
or immediately allocate that power. These settings are only used for configuring
a maximum amount of power that may be used, any unused power is still
available and remains a part of the overall PoE budget.
Setting Timers and Other User-Defined PoE Power Rules
The lanpower power-rule command allows user to set additional rules for PoE power (e.g., setting PoE
to turn on or off on specific dates or at specific times). Refer to the OmniSwitch AOS CLI Command
Reference Guide for more information.
