PASSWORD Command (Change Passwords)
Use the PAS command (see Table 7.32 and Table 7.33) to change existing
passwords.
The factory-default passwords are as shown in Table 7.34.
To change the password for Access Level 1 to #Ot3579!ijd7, enter the
following command sequence:
Similarly, use PAS 2 to change Level 2 passwords and PAS C to change
Level C passwords.
Passwords can contain as many as 12 characters. Upper- and lowercase letters
are treated as different characters. Strong passwords consist of 12 characters,
with at least one special character or digit and mixed-case sensitivity, but do
not form a name, date, acronym, or word. Passwords formed in this manner
are less susceptible to password guessing and automated attacks.
Examples of valid, distinct, and strong passwords are shown below:
➤ #0t3579!ijd7
➤ $A24.68&,mvj
➤ (Ih2dcs)36dn
➤ *4u-Iwg+?lf-
