SmartCloud Radio Node - SCRN 200 Hardware Installation Guide

SpiderCloud Wireless, Inc.

Sequence description:

1. When the radio node is powered on, the device sends a DHCP Request to the network DHCP

server to get IP information.

2. The DHCP server is configured to use vendor Option 43. The server responds with the IP

addresses of the radio node and the services node (the master of the radio node). The following

example shows a sample configuration from a DHCP server, where 10.1.30.99 is the IP address of

the radio node’s controlling services node:

option space SPIDERCLOUD;

option SPIDERCLOUD.access-controller code 102 = string;

option SPIDERCLOUD.access-controller "10.1.30.99;";

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 Join Response from the services node will be one of the following:

— Join Grant: Permit the radio node to join the services node.

— Redirect: Redirect the radio node to join a different services node if you have multiple

services node units configured in the network.

— Denied: The security signature on the radio node does not match what the services node

expects. The client is untrusted and treated as a rogue device.

5. The arrival sequence begins. Based on the configuration of the radio node, the radio node will join

the system and get its configuration. The services node sends the SpiderCloud software image

(the system image and configuration settings) to the radio node.

6. The radio node reboots and mounts the SpiderCloud software image as a RAM-based file system.

7. The radio node contacts the services node and joins the network.
