Setting The Poe Operational Status; Configuring The Total Power Available To A Port - Alcatel-Lucent OmniSwitch 6850E Series Hardware User's Manual

Configuring Power over Ethernet Parameters

Setting the PoE Operational Status

Enabling PoE
By default, Power over Ethernet is administratively enabled in the switch's system software. However, in
order to physically activate PoE, you must issue the
before any connected PDs will receive inline power.
To activate power to PoE-capable in a switch, enter the corresponding slot number only. For example:
-> lanpower start 3
If power to a particular port has been disconnected via the
power to the port by specifying both the slot and port in the command line. For example:
-> lanpower start 3/11
Note. You cannot use the slot/port syntax to initially activate PoE on a port. This syntax is intended only
to reactivate power to those that have been disconnected via the
activate PoE, you must use the lanpower start slot syntax only, as described above.
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 8/22
To disable PoE for all PoE-capable in a slot, enter the corresponding slot number only.
For example:
-> lanpower stop 8

Configuring the Total Power Available to a Port

By default, each port is authorized by the system software to use up to a maximum amount of milliwatts to
power any attached device.
You can either increase or decrease this value based on the allowed ranges specified in
"Managing Power over Ethernet (PoE)."
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
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 3/12 power 3000
reduces the power allowance on slot 3 port 12 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).
