Initial IP address

Previous controllers shipped with a static IP address. To facilitate bulk deployment, Edge devices are shipped with a one-time feature enabled that allows the controller to initially attempt to connect to a DHCP server.

Upon first startup, when IP connectivity is detected, the Edge-10 initially requests an IP address via DHCP. If a DHCP address is not found, the controller reverts to a static IP address based on its serial number. See the following section for examples..

This feature only applies during the first power up cycle with an active Ethernet connection. At all other times the network settings are set or modified the same as on the JACE-8000.

NOTE: For this onetime feature to execute there must be an active Ethernet connection. A flag is maintained that enables this feature. This feature will execute once and then the flag will be disabled. During a factory restore the flag enabling this is reset to enabled

Fallback Static IP

The fallback static IP is built using the last four digits of the devices serial number. Route and subnet mask are set appropriately.

Static IP : 192.168.1xx.xx where xx.xx are numbers lifted from the serial number, as shown in the following two examples:.
- For serial number : 010106 the resulting IP is: 192.168.101.06
- For serial number: 106 the resulting IP is: 192.168.101.06
Route : 192.168.1.1
The default subnet mask is: 255.255.0.0

Summary

The follow behaviors apply to the factory state:

Edge device power ups with no Ethernet cable connected.
1. Maintains the factory shipped state
Edge device power ups with the Ethernet cable connected and DHCP server on the network.
1. The device obtains an IP address from the DHCP server
2. Fallback mechanism is disabled
Edge device power ups with Ethernet cable connected and no DHCP server or DHCP fails.
1. Apply fallback static IP
2. Fallback mechanism disabled
