Step 3 With two user-provided screws, attach the mount bracket assembly to a wall or ceiling. The
screw holes are sized for an M4 (#10) or larger screw. Ensure the screws have a snug fit
onto the studs, sheetrock, anchor, or other material you are bolting onto and that you
match the screw head with the appropriate cutout hole size on the bracket.
If needed, use a flat washer between the bracket and screw head to ensure a secure
fastening.
Step 4 Insert the RJ-45 connector into the Ethernet port as shown in Figure 13:
Figure 13 Route and Terminate the Cable
Step 5 Insert the radio node into the mount bracket.
Step 6 Push as much cable back through the wall or ceiling as possible. The mount bracket
assembly has room for some cable slack.
Installing the Radio Node (Method 2)
Use this method with the 1.25 inch bracket when routing an exposed Ethernet cable directly to the radio
node.
To route the cable openly and mount the radio node
Step 1 With two user-provided screws, attach the mount bracket assembly to a wall or ceiling. The
screw holes are sized for an M4 (#10) or larger screw. Ensure the screws have a snug fit
onto the studs, sheetrock, anchor, or other material you are bolting onto and that you
match the screw head with the appropriate cutout hole size on the bracket.

Completing the Installation
Step 1 Attach a padlock or cable tie wrap into the provided slot to secure the unit to the mount
bracket.
Figure 16 Padlock and Lock Holes
The lock in the above figure is shown schematically. The orientation is for illustration
purposes (not accurate) since the bracket is typically wall or ceiling mounted.
Step 2 The radio node boots up and attempts to connect to the services node. Refer to Boot
Sequence and Services Node Communication on page 20 for more information.
Detaching the Radio Node from the Mount Bracket
To remove the radio node from the bracket assembly
Step 1 If needed, remove the padlock or cable tie wrap securing the radio node.
Step 2 Slide the radio node out of the mount bracket.
Step 3 Detach the RJ-45 clip from the Ethernet port and remove the cable from cable brackets
and cable opening.

Boot Sequence and Services Node Communication
On initial boot, the radio node performs the following boot sequence. When finished, all devices are
reachable. Figure 17 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.
6. The radio node boots up the received SpiderCloud software package.
7. The radio node establishes an IPsec tunnel with the services node. Based upon the radio
configuration, the radio node loads the appropriate protocol elements and joins the network.
