Equinox ESP-2 OPTO Serial Hub Installation and User Guide
4.3 Passwords
The ESP-2 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-2 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 ESP-2 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 sensitive and may contain any alphanumeric characters.
3. Repeat the new password in the New Password (re-enter) field.
4. Click the
Apply
button.
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.
4.4 Displaying or Changing Network Configuration Values
The Network Configuration display includes the ESP-2 serial hub IP address, subnet
mask and gateway address. You must configure a nondefault IP address for the ESP-2
hub before the hub becomes operational.
To display or change network configuration values:
1. From the Main Menu, select
Network Configuration
.
2. To change an entry, enter a valid value in the IP Address, Subnet Mask and Gate-
way Address fields. The addresses must be entered in standard IP dot notation.
The gateway address must be in the same subnet as the IP address. You cannot
set the IP address to: a Class A address of 0.0.x.x, a loopback address of
127.x.x.x, the default value of 192.1.1.1 or an address at or above 248.x.x.x. The
subnet mask cannot be 0.0.0.0.
3. If you changed any values, click the
Apply
button. The EEPROM configuration is
modified, but the change does not take effect until the next reboot of the ESP-2 hub.
