Boot Sequence and Services Node Communication
On initial boot, the radio node performs the following boot sequence. When finished, all devices are
reachable.
shows the radio node boot sequence:
Figure 17
Radio Node Boot Sequence
Boot Sequence:
1.
When the radio node is powered on, the device sends a DHCP Request to the services node DHCP
server to get IP information. The DHCP server is configured on the services node to respond only to
DHCP requests from SpiderCloud Wireless radio nodes. Refer to the
SpiderCloud OS (SCOS)
Administrator Guide
for more information about the services node DHCP server configuration.
2.
The server responds with the IP addresses of the radio node and the services node (the master of the
radio node).
3.
Using its own IP address, the radio node sends a Join Request message to the services node. The
radio node seeks to join the cellular network.
4.
The services node responds with a Join Response message indicating whether the radio node is
allowed to join the network or not.
5.
The arrival sequence begins. The services node sends the SpiderCloud software image to the radio
node.
