Configuring the Total Power Available to a Port, Disabling PoE

Page 90 highlights

Configuring Power over Ethernet Parameters Managing Power over Ethernet (PoE) Disabling PoE To disable PoE on a particular slot or port, use the lanpower stop command. 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 Available to a Port A default amount of milliwatts, as noted in the specifications table, is available 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 available to an individual port may provide a more demanding Powered Device (PD) with additional power required for operation. Decreasing the total power available 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 available to an individual port, use the lanpower power command. 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 Available 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 available to a slot may provide more demanding Powered Devices (PDs) with additional power required for operation. Decreasing the total power available 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 lanpower start command. page 5-6 OmniSwitch 6400 Series Hardware Users Guide July 2010

Disabling PoE
To disable PoE on a particular slot or port, use the
lanpower stop
command.
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 Available to a Port
A default amount of milliwatts, as noted in the specifications table, is available 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 available to an individual port may provide a more demanding Powered Device
(PD) with additional power required for operation. Decreasing the total power available 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 available to an individual port, use the
lanpower power
command.
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 Available 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 available to a slot may provide more demanding Powered Devices (PDs) with
additional power required for operation. Decreasing the total power available 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
lanpower
start
command.
