Chapter 1: Product description
PTP 650 RADIUS supports the standard Service Type attribute to indicate authentication roles of
System Administrator and Read Only together with a vendor specific attribute to indicate
authentication roles of Security Officer, System Administrator, and Read Only.
Remote authentication can be used in addition to local authentication, or can be used as a
replacement for local authentication. If remote and local authentications are used together, PTP
650 checks log in attempts against locally stored user credentials before submitting a challenge
and response for remote authentication. Remote authentication is not attempted if the username
and password match locally stored credentials, or fails against the local database.
RADIUS is only available when PTP 650 is configured for Identity-based User Accounts. For more
information, refer to

Simple Network Time Protocol (SNTP)
The clock supplies accurate date and time information to the system. It can be set to run with or
without a connection to a network time server (SNTP). It can be configured to display local time by
setting the time zone and daylight saving in the Time web page.
If an SNTP server connection is available, the clock can be set to synchronize with the server time
at regular intervals. For secure applications, the PTP 650 can be configured to authenticate
received NTP messages using an MD5 signature.
