ASSIGNING A PRIMARY IP ADDRESS TO ENET 1 ON EACH CONTROLLER
SNAP PAC Redundancy Option User’s Guide
18
If the device is not currently in BootP mode, see form 1592, the
SNAP PAC S-Series Controllers User’s
Guide
, to reset the controller.
SNAP PAC S-series controllers each have two separate Ethernet network interfaces; Wired+Wireless
models have an additional wireless interface. Each interface has a separate MAC address and
therefore takes a separate, unique IP address. However, only ENET 1 sends a BootP request. Once you
have assigned the primary IP address to ENET 1, you can assign the secondary address to ENET 2.
ENET 1 is used to communicate on the Ethernet network. ENET 2 is used by the controllers to
communicate with each other.
NOTE: BootP broadcasts cannot get through a firewall in the PC where PAC Manager is running. Make sure
any firewall in the computer (such as the built-in firewall in Windows) is disabled before you try to assign
IP addresses. Firewalls in a router should not be a problem.
