3. The Web Interface
3.4 Configuration
The Configuration menu group contains seven submenus: Device Settings, Contacts, Network, Actions, Scheduling, Security and Log Settings
(Figure 3-15). The available configuration options will vary by device.
3.4.1 Configuration / System Settings
System-level settings will include Watchdog configuration options, selection of the default time source and time zone offset.
Figure 3-15: Configuration Menu
The Watchdog Probe function allows the network interface of the LX Platform device to reboot itself if it loses network communication. This reboot
will not affect functionality of the LX device; for example, a PDU will continue distributing power through its outlets while the interface reboots.
• Active – Enables or disables the probe.
• Period -- The number of minutes between probe attempts. The range of valid values is 3 to 1440.
• Attempts -- The number of consecutive probes after which, if unsuccessful, the interface reboot will be triggered. The range of valid values is
3 to 10.
• Primary address – The IPv4 address of the primary probe target or the Fully Qualified Domain Names (FQDN). For the NTP Probe, the IPv4
address or FQDN of the NTP server should be entered.
• Primary port – The port number of the primary probe target (NTP server).
• Secondary address – The iPv4 address or the FQDN of the secondary probe target. This can be optionally set as a means to double-check if
network connectivity was lost. If probes to the primary address fail, but probes to the secondary address are successful, the reboot will not be
triggered.
The Time Source choices are Network and RTC. If Network is chosen, enter the Primary NTP Source (and Secondary NTP Source, if desired) in
the appropriate fields. The default Time Zone Offset is UTC; to change this, select the desired selection from the pulldown menu. Ensure that you
click on the [Save] icon after entering or editing these fields.
The default Ping and NTP watchdog probe events are configured to log to the event log and reboot the card 30 seconds after the event is
detected. Probes will become active once they complete a successful handshake with the remote host. An unsuccessful handshake will be
captured in the event log, as well as the Telnet/SSH for Auto Probes status.
