Equinox ESP-2 OPTO Serial Hub Installation and User Guide
5.3 Passwords
The configuration utility requires an administration password for access. When the hub
ships (or after it is reinitialized), there is no configured password. After you create a
password, you will be prompted for it each time you access the configuration utility.
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 configuration utility or the web interface.
The administration password is common between the configuration utility and the
web interface. No encryption is used when entering the password with the
configuration utility.
To set or change the password:
1. From the Top Menu, enter
5
to select Change password.
2. You are prompted for the new password. Enter a 5-32 character password. Pass-
words are case sensitive and may contain any alphanumeric characters.
3. You are prompted to re-enter the new password. Retype the new password. A
confirmation message will appear.
5.4 Displaying or Changing Network Configuration Values
The Network Configuration display includes the ESP-2 serial hub’s IP address,
subnet mask and gateway address. You must configure a nondefault IP address before
the hub becomes operational.
To display or change network configuration values:
1. In the Top Menu, enter
0
to select Server Configuration.
2. In the Server Configuration menu, enter
1
to select Network configuration. The
display shows the IP address, subnet mask and gateway address.
3. You are prompted to modify any values. Enter
y
for yes or
n
for no.
To change an entry, enter a valid value when prompted. 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.
4. If you changed any values, the new values are displayed and you are prompted to
confirm the changes. Enter
y
for yes or
n
for no.
The EEPROM configuration is updated immediately, but the change does not take
effect until the ESP-2 serial hub reboots. If the IP address had not been previously set
(or the hub has been reinitialized), the hub reboots automatically. If you are changing
an existing address, you must expressly initiate a reboot using the configuration
utility (see
on page 30), the web interface (see
on page 22) or the RESET button on the front panel (see
