1. Press and hold the Help button on the System IP Phone.

3. To display the firmware version, press the Up softkey.
14.3 Upgrading Automatically
This procedure causes all IP Phones to attempt firmware upgrade the next time
they connect to the GCD-CP10. This can make the upgrade procedure easier, as
it is not necessary to visit every telephone to perform the upgrade.
This can cause problems if, for example, a PoE (Power over Internet) switch is
used. When the PoE switch is powered up, all telephones connect to the FTP/
TFTP server at the same time. This causes a large amount of data for the FTP/
TFTP server to transfer over the data network.
To avoid this, connect the telephones to the PoE switch gradually, to allow time for
each telephone to upgrade before connecting the next.
To enable automatic upgrade:
When the IP phone boots up and connects to the SV9100 it receives download
information from the system that includes firmware information. When the SV9100
reports a version that is different than the version the IP phone is currently
utilizing, the IP phone will initiate the upgrade procedure.
