Connect a Second BB424 to the First BB424:

This procedure assumes that you have already connected one BB424 to a phone, as described in

"Connecting a Single BB424 to a Phone" on pg. 1.

① Ensure that the host ShoreTel IP485g phone and the first BB424 are powered on and running.

② The BB424 is shipped with the micro USB cable already plugged into the back of it. Ensure

that this cable is plugged in firmly.

③ Thread the free end of the USB cable from the side of the second BB424's stand through the

side of the first BB424's stand. Plug the USB jack into the Out 2 USB port on the first BB424.

④ On the rear of the first BB424, connect the AC adapter. Then connect the power source to

your wall outlet.

After a few seconds, the second BB424 powers on and runs through a series of system tests. The

BB424 automatically updates to the firmware version of the host phone. The first BB424 discon-

nects and reconnects, and the pages on each BB424 are resequenced to reflect the number of

BB424 devices.
