Note:
As of Software Release 3.0, the USB interface supports USB Login and using
Note:
digital pictures from a USB device as a screensaver. As of Software Release 2.0,
the USB interface supports importing/exporting contact lists on 9620, 9630, 9640,
and 9650 IP Telephones via a Flash drive. The only exceptions are the 9610 and
9620L models, which do not have a USB jack. Since the power consumption of
the drive will vary from product to product, it is not possible to state what its
impact on PoE power class will be. When the drive attempts to register with the
telephone, the telephone will determine if its current power class setting is
adequate to support the drive. If power is adequate, the telephone will let the
drive register. If it is not adequate, the telephone will prompt the user to change
the power class to Class 3 by changing the IEEE power switch setting from "L" to
"H." In extreme situations, the total power consumption with the addition of a USB
device may be greater than what the Class 3 power source can provide. In that
case, the telephone detects this and instructs the user to use an Auxiliary power
supply or to temporarily disconnect one or more of the modules while the USB
device is in use.
The system parameter USBPOWER determines for which power class(es) to
enable power to the USB interface; see Chapter 7 in the Avaya one-X™
Deskphone Edition for 9600 Series IP Telephones Administrator Guide for
information.
