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.

Radio Node LED Boot Sequence
The radio node state machine is sequential and progresses in the following order:
State 0 -> State 1 -> State 2 -> State 3 -> State 4 -> State 5
A normal boot sequence transitions through all these states sequentially and the LED state transitions
accordingly. If the radio node fails to transition to the next state, the system restarts the boot sequence,
starting with State 0. You can determine the progress during the booting stages by observing the LED color
transitions. On failure, the last LED state will display the state that encountered the failure. Ta bl e 6 shows
the radio node boot sequence and corresponding LED behavior:
Table 6: Radio Node LED Boot Sequence
State LED Color Description Possible Failures and Actions
0. Power On/
Reset
1. DHCP Solid
2. Join Solid
Flashing
Green
Red
Blue
This is the initial state on startup.
The radio node bootup is controlled by
firmware in this state.
It will go through a lamp test in this
state. A lamp test involves cycling
through all LED colors.
The radio node starts by sending out a
DHCP Request.
The radio node moves to the next state
(State 2) upon receiving a DHCP
response and an IP Address.
The radio node has an IP Address and
sends a UDP Join request to the
Serving services node.
The radio node moves to the next state
(State 3) upon getting a JOIN GRANT
from the services node.
This state should be very short
lived and should transition to the
next state immediately.
A radio node should not stay in
this state indefinitely.
Note: Flashing Green is also
used to indicate a radio node
that has been administratively
disabled. This can be
determined from the CLI.
No DHCP Response, IP
Address not allocated.
Check cabling, DHCP Server
configuration.
No IP reachability to the
services node.
Check IP network between
radio node and services node
for routing issues.
3. TFTP Flashing
Blue
The radio node proceeds next to
download the operating system image
from the services node.
The radio node moves to the next state
(State 4) after the image has been
downloaded.
Failure to download TFTP
image.
Check firewall between radio
node and services node.

connectivity with the service node.
The operating system is running. The
radio node continues the startup
sequence, but is now controlled by the
services node.
Failure to start the operating

This normally points to a
software/build issue. Please
contact SpiderCloud support.
The operating system is up and

Any subsequent state
transitions can now be tracked
from events and logs on the
services node.
Radio Node LED Management
The LED display is active by default, but can be deactivated in light-sensitive environments as needed.
Even when the display is disabled, the LED will be lighted during the following conditions:
• while the radio node is booting
• if the radio node or cell is in fault state
• if there is an active emergency call
• if the locate radio node feature is active
• if the follow IMSI feature is active
Ta bl e 7 shows the default LED behavior of the radio node:
