Note:
The phone monitors its power consumption to stay within the guidelines of the IEEE
802.3af specification. Connecting a Dual Headset Adapter could lead to a change
in power classification and may require a change to the switch setting as well.
Note:
For the 9611G and 9641G, the USB interface supports USB Login, using digital
pictures from a USB device as a screensaver, and importing/exporting contact
lists via a Flash drive. The only exceptions are the 9608, which does not support
USB devices, and the 9621G model, which does 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 alert the user to
change the power class 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 H.323 Administrator Guide for information.
Important:
The last step in assembling the 9600 Series IP Deskphone must be applying
power with any modules and/or adapters (and excluding USB devices, headsets,
etc.). Apply power either by plugging the power cord into the power source (local
