Basic Relay Operations
Changing the Default Passwords
Changing the Default Passwords: Terminal
Step 1. Confirm that the relay is operating (see Connecting and
Applying Power).
Step 2. Establish communication with the relay (see Making an
EIA-232 Serial Port Connection to learn how to use a terminal
to communicate with the relay).
Step 3. Enter Access Level C (level 2 is sufficient except when
changing the level C password).
a. Using a communications terminal, type ACC <Enter>.
b. Type the Access Level 1 password OTTER and press
<Enter>.
You will see the Access Level 1 => prompt.
c. Type2AC <Enter>.
NOTE: Passwords are case sensitive;
you must enter passwords exactly as
set.
d. At the password prompt, type TAIL <Enter>.
e. Type CAL <Enter>.
f. At the password prompt, type Sel-1 <Enter>.
You will see the Access Level C ==>> prompt.
Step 4. To set a new password for Access Level 2, type the following:
PAS 2 <Enter>
Step 5. Before you can change to a new password, the relay prompts
you to first confirm the existing password. Enter the existing
password and press <Enter>.
Old Password: ?**** <Enter>
Step 6. The relay prompts you for the new password, and a
confirmation of the new password, as follows:
New Password: ?**** <Enter>
Confirm New Password: ?**** <Enter>
Password Changed
CAUTION: This password can be strengthened. Strong
Passwords do not include a name, date, acronym or
word. They consist of the maximum allowable
characters, with at least one special character,
number, lower-case letter, and upper-case letter. A
change in password is recommended.
Notice that the new password is not displayed. After the
confirmation, the new password is in effect.
Step 7. Set new passwords for each access level.
In a similar manner as the previous step, create new strong
passwords for each access level.
Step 8. Commit these passwords to memory, permanently record your
new passwords, and store this permanent record in a secure
location.
To eliminate password verification for an access level, enter DISABLE in
place of the new password. This action will disable the password of that level;
therefore, the relay does not check for a password upon entering that access
level.
