Configuring The Total Power Allocated To A Port; Configuring The Total Power Allocated To A Switch - Alcatel-Lucent OmniSwitch 6400 Series Hardware User's Manual

Configuring Power over Ethernet Parameters
Disabling PoE
To disable PoE on a particular slot or port, use the
To disable PoE on a specific PoE-capable port, enter a slot/port number. For example:
-> lanpower stop 1/22
To disable PoE for all PoE-capable in a slot, enter the corresponding slot number only.
For example:
-> lanpower stop 1

Configuring the Total Power Allocated to a Port

PoE automatically allocates a default value of milliwatts, as noted in the specifications table, for each port
on the OmniSwitch. In other words, each port is authorized by the system software to use up to the default
amount of milliwatts to power any attached device.
You can either increase or decrease this value based on the ranges listed in the specifications table.
Increasing the total power allocated to an individual port may provide a more demanding Powered Device
(PD) with additional power required for operation. Decreasing the total power allocated to a port helps to
preserve inline power and assists in the overall management of the switch's power budget.
To increase or decrease the total power allocated to an individual port, use the
Since you are setting the power allowance for an individual port, you must specify a slot/port number in
the command line. For example, the syntax
-> lanpower 1/12 power 3000
reduces the power allowance on port 1/12 of the OmniSwitch to 3000 milliwatts. This new value is now
the maximum amount of power the port can use to power any attached device (until the value is modified
by the user).

Configuring the Total Power Allocated to a Switch

Like the maximum port power allowance, the system software also provides a maximum slot-wide power
allowance. Each slot is authorized by the system software to use up to default value of Watts, as noted in
the specifications table, to power all devices connected to it depending on which power supply is used.
As with the maximum port power allowance, this value can be either increased or decreased. Values may
range from the values listed in the specifications table and are dependent upon the installed power supply.
Increasing the total power allocated to a slot may provide more demanding Powered Devices (PDs) with
additional power required for operation. Decreasing the total power allocated to a slot helps preserve inline
power and assists in the overall management of the switch's power budget.
Note. Before changing the maximum slot-wide power allowance, you must disable PoE for the slot via the
lanpower stop command. Once the new value is assigned, re-enable PoE for the slot via the
start command.
