Boot Sequence and USC 8088 Controller Communication
On initial boot, the small cell module performs the following boot sequence. When finished, the module is reachable.
Figure 4: Small Cell Boot Sequence
Boot Sequence:
1
When the small cell is powered on, the device sends a DHCP Request to the controller DHCP server to get IP information. The
DHCP server is configured on the controller to respond only to DHCP requests from Cisco Systems small cells. Refer to the Cisco
USC 8000 Series OS Administrator Guide for more information about the controller DHCP server configuration.
2
The server responds with the IP addresses of the small cell and the controller (the master of the small cell).
3
Using its own IP address, the small cell sends a Join Request message to the controller. The small cell seeks to join the cellular
network.
4
The controller responds with a Join Response message indicating whether the small cell is allowed to join the network or not.
