Important. In order to comply with 911 emergency requirements, PoE power redundancy status must be
enabled at all times.
Note. For information on the priority disconnect function, refer to “Understanding Priority Disconnect” on
page 3-25.
Setting the Capacitor Detection Method
By default, the PowerDsine capacitor detection method is disabled on the OS7-ENI-P24. To enable it use
the lanpower capacitor-detection command by entering lanpower capacitor-detection followed by the
slot number of the OS7-ENI-P24 and enable.
For example, to enable the capacitor detection method on the OS7-ENI-P24 with slot number 2 enter:
lanpower capacitor-detection 2 enable
To disable it use the lanpower capacitor-detection command by entering lanpower capacitor-detection
followed by the slot number of the OS7-ENI-P24 and disable.
For example, to disable the capacitor detection method on the OS7-ENI-P24 with slot number 2 enter:
lanpower capacitor-detection 2 disable
Note. The capacitive detection method should only be enabled to support legacy IP phones only—this
feature is not compatible with IEEE specification 802.3af. Please contact your Alcatel sales engineer or
Customer Support representative to find out which Alcatel IP phones models need capacitive detection
enabled.
