Options
If you want to change the default password of the NJ240FX or change SNMP
community strings, you can configure these settings from either the Local
Configuration Manager or the Central Configuration Manager (covered in the
next chapter). In the Local Configuration Manager, both settings are found under
the Advanced tab.
NOTE: By default, the NJ240FX is configured to automatically obtain an IP
address from a DHCP server. If no DHCP server exists, or if the NJ240FX cannot
obtain an IP address, it will default back to its previously configured static IP
address. If it had previously been assigned an IP address, it will default to that
one. If it did not, it will default to the static IP address of 192.168.1.252.
WARNING: If you lock an IP address and reserve it for this IntelliJack, make sure
you configure your DHCP server so it won’t distribute that address to other
devices.
