Setting Web Access Control By using a web browser to access the IP address set for the adapter, you can
view the adapter’s web pages for information about the adapter, its
connected drive, and other DPI devices connected to the drive, such as
HIMs or converters. Additionally, the adapter can be configured to
automatically send e-mail messages to desired addresses when selected
drive faults occur and/or are cleared, and/or when the adapter takes a
communication or idle fault action. For more details on the adapter’s web
pages, refer to
Chapter 6 , Viewing the Adapter’s Web Pages .
By default, the adapter web pages are disabled. Refer to Figure 2.1 and set
the Web Pages Switch (SW2) to the “Enable Web” (up) position.
Important: For a change to the switch setting to take effect, the adapter
must be reset (see Resetting the Adapter on page 3-12 ).
Bit 0 of Parameter 37 - [Web Features] is used to protect the configured
settings for e-mail messaging. By default, settings are not protected and the
user can make changes. To protect the configured settings, set the value of
E-mail Cfg Bit 0 to “0” (Disabled). You can unprotect the configuration by
changing Bit 0 back to “1” (Enabled). E-mail messaging will always remain
active regardless of whether or not its settings are protected — unless e-mail
messaging was never configured. For more information about configuring
adapter e-mail messaging or to stop e-mail messages, refer to
Configure
E-mail Notification Web Page on page 6-6 .
