Action. ZIP2x2 initiates TFTP read request for ZIP2x2_version bin.

provided by DHCP option #66 (for example, ZIP2x2_0_1_34.bin).
4.4.4.10 Step 10
Action. The ZIP2x2 receives TFTP data (ZIP2x2_version.bin) from the TFTP Server
Description. After downloading the software version the ZIP2x2 reboots and repeats all of the
steps (except for retrieving software). At this point, the ZIP2x2 performs a checksum verification

information stored internally to the .bin file, the phone indicates an error and loads the previous
software version.
4.4.5 Summary
For a user, the process of updating the software is fully automatic. The administrator of the
network can initiate this process at any time. When the phone is idle, it will start the process of

To start the update process, the software in the phone restarts and displays:
The phone displays this message using different characters than normal, and only two lines of
text. It shows the progress of the update on the second line using periods (full stops). There are
16 characters on the line and each period indicates the phone has completed about 6% of the
programming task. The phone shows a new period every one to three seconds.
Important
Do not disturb the phone during the update process. You cannot use the phone

on. After about 15 seconds the phone displays the idle display and is ready to use.
If the software update process fails, the phone may display:
