ESP-4 MI Serial Hub Installer/User Guide
The ability to access the web interface is a configurable feature which is enabled by default; see
If you click the Documentation link at the bottom of the Main Menu, you may then choose to view
this document (Installer/User Guide) or a sample configuration file.
Passwords
The web interface requires an administration password for access. When the hub ships (or after it is
reinitialized), there is no configured password. When you access the ESP-4 MI serial hub, you are
prompted for a username and password. The username field is ignored. If a password has not yet
been set, any alphanumeric password will be accepted. Once you enter the web interface, you will
be required to configure a password before you may perform any other operations.
Some browsers have a feature to remember the password. If this is enabled, you won’t need to enter
the password at the username/password prompt in future sessions.
The administration password is common between the web interface and the configuration utility.
When using the web interface, the password is encrypted by the browser when it is sent to
the interface.
If you reinitialize the serial hub, the password is lost. You will be required to create a password the
next time you access the web interface or the configuration utility.
To set or change the password:
1.
From the Main Menu, select
Change Password
.
2.
Enter the new 5-32 character password in the New Password field. Passwords are case sensi-
tive and may contain any alphanumeric characters.
3.
Repeat the new password in the New Password (re-enter) field.
4.
Click
Apply
.
Once the password is validated, the EEPROM configuration will be updated. A reboot is not
required. The new password will be required the next time the web interface or the configuration
utility is accessed.
