SMP 300 Series • Remote Communication and Control 109
The SMPsends the copyright messages under the following circumstances:
• If the SMP is off and an RS‑232 connection is already set up (the PC is cabled to
the SMP and a serial communication program such as HyperTerminal is open), the
connected unit sends these messages via RS‑232 when first powered on.
• If the SMPis on, it sends the copyright messages when a Telnet connection to the
SMPis first opened. The day of the week, date, and time are shown when the SMP is
connected via Telnet, but not via RS‑232. If using a Telnet connection, the copyright
message, date, and time is followed by a password prompt.
Password Information
NOTE: The factory configured passwords for all accounts on this device have been set
to the device serial number. In the event of a complete system reset, the passwords
convert to the default, which is no password (see Users and Roles on page86 to
change a password).
The
]
Password: prompt requires a password (administrator level or user level) followed by
a carriage return. The prompt is repeated if the correct password is not entered.
If the correct password is entered, the unit responds with
]
Login Administrator
]
or
]
Login User
]
, depending on the password entered. If passwords are the same for both
administrator and user, the unit defaults to administrator privileges.
