338 IP Line administration
When an IP Telephony node is first installed, the IP Phone Installer
Password is not defined or enabled by default. To prevent users from
inadvertently re-configuring the Node ID and TN on their IP Phones, enable
the IP Phone Installer Password after the IP Phone is initially installed and
the system is in service.
Password security controls access to an IP Phone TN for the purpose
of registering to a different virtual line TN on the Call Server after the IP
Phones have been installed. A password is not encrypted by the IP Phone
or the Voice Gateway Media Card.
By default, when a node is initially installed, the administrative password
and the temporary password are not defined, and the password feature
is disabled.
The nodePwdSet "password" command configures and enables the
password. When the password is enabled and configured, the screen on the
IP Phone displays the four digit Node ID and a Password prompt, instead of
the Node ID and TN fields.
If the nodePwdEnable command is entered before the password is set
using the nodePwdSet command, the password is also enabled with a null
(zero-length) password and as a result, the password and TN prompts are
also never displayed on the IP Phones.
The administrator normally uses the Administrative IP Phone Installer
Password if it is necessary to install a new telephone or change the
configuration (node ID and TN) of an existing telephone.
If an IP Phone cannot be installed because a prompt for a node ID and TN
does not appear, log into a Voice Gateway Media Card and check the status
of the password using the nodePwdShow command.

WARNING
The nodePwdSet command with no "password" parameter
enables the administrator password and sets a null (zero-length)
password.
Enabling the administrator password and setting a null password
makes it impossible to install the IP Phones because the Node ID
and TN prompts are not displayed on the telephone screen.
Always specify the password parameter when issuing the
nodePwdSet command. This password parameter is 6 to 14
digits. The valid characters are 0 to 9, *, and #.
