Appendix K: Additional PX3 Information

Role of a DNS Server
As Internet communications are carried out on the basis of IP addresses,
appropriate DNS server settings are required for mapping domain
names (host names) to corresponding IP addresses, or the PX3 may fail
to connect to the given host.
Therefore, DNS server settings are important for external authentication.
With appropriate DNS settings, the PX3 can resolve the external
authentication server's name to an IP address for establishing a
connection. If the
SSL/TLS encryption is enabled, the DNS server
settings become critical since only fully qualified domain name can be
used for specifying the LDAP server.
For information on external authentication, see
Setting Up External
Authentication
(on page 257).
Cascading Troubleshooting
Any accessibility problem occurred on one of the devices in the
cascading chain may result in failure to access all downstream slave
devices that are connected to it.
Possible Root Causes
The following lists the network accessibility issues and possible root
causes.
You can always troubleshoot the software settings by connecting the PX3
to a computer if network access to that PX3 fails. See
Connecting the
PX3 to a Computer
(on page 28).
