• NTP Timeout: The amount of time in seconds, that will elapse between each
attempt to contact the NTP server. When the initial attempt is unsuccessful,
the Outlet Managed PDU will retry the connection four times. If neither the

the IP address or domain names defined via the Primary and Secondary NTP
Address prompts, or to a new address or domain defined via the Test NTP

When properly configured and enabled, the Invalid Access Lockout feature will
watch all login attempts made at the Network Port and serial Setup Port. If the port
exceeds the selected number of invalid attempts, then the port where the Invalid
Attempts occurred will be automatically disabled for a user-defined length of time
(Lockout Duration.) The lockout feature uses two separate counters to track invalid
access attempts:
• SetUp Port Counter: Counts invalid access attempts at the Setup Port. If
the number of invalid attempts at the port exceeds the user-defined Lockout
Attempts value, the port will be locked.
• Telnet, SSH and Web Browser Counter: Counts all invalid attempts to access
command mode via Telnet, SSH or Web Browser interface. If the number of
cumulative invalid attempts exceeds the user-defined Lockout Attempts value,
then the Network Port will be locked.
