About this Manual
This guide provides the system specifications of the SpiderCloud Wireless® Radio Node 330 (SCRN-330).
It includes detailed hardware installation instructions, the boot sequence, and expected LED behavior both
during the boot-up and under operating conditions. An appendix shows the radio node antenna patterns.
The primary audience for this guide includes network planners, system administrators and installation
personnel. It assumes you have knowledge about networking principles, networking configuration, site
preparation, powering, and experience in hardware installation and maintenance.
Product Overview
The SCRN-330 is a Time Division Duplexing (TDD) radio node that connects to a services node. It uses
GPS to achieve phase synchronization with macro networks. Each radio node support 128 connected
users and up to 8 bearers per UE. It supports peak transmit power of 2x250mW and uses Powered over
Ethernet plus (PoE+). This radio node supports CBRS technology, which enables services such as private
LTE networks and neutral host systems.
SpiderCloud’s scalable small cell system, called an Enterprise Radio Access Network (E-RAN), hides the
complexity of radio management and mobility and provides operators with a single touch-point to
aggregate and manage a large network of LTE small cells. The SCRN-330 leverages Carrier Aggregation
(CA) and Self-Organizing Networks (SON) capabilities.
The SCRN-330 is easy to install and connects to the existing enterprise LAN using standard Ethernet
cabling or to a dedicated LAN infrastructure deployed for use by the operator. SCRN-330 radio node are
managed by the SpiderCloud SCSN-9000 services node installed in the enterprise or in a centralized
location such as a data center.
The SCRN-330 has no fans and is convection cooled. Antennas are built-in with an orderable option for
SMA connectors for use with external antennas.
The SCRN-330 utilizes on-chip Trusted Platform Module (TPM) functions to implement secure boot, and
establish certificate-based IPsec tunnel to SpiderCloud services node for all traffic. There is no
management or console port on the radio node. The radio node can be physically locked to prevent theft.
Figure 1 on page 6 shows the logical architecture of the SCRN-330 in the network:

The Top-Panel LED
The radio node has one top-panel tricolor (RGB) LED to indicate power and status. This is the only LED
visible under normal operating conditions. When the radio node initially boots the LED cycles through a
number of colors and flashing behaviors until it is fully operational. Status indications: boot, normal,
disabled, fault, emergency call, radio node tracking.
Figure 6 Radio Node Tricolor LED
Input Power
The radio node receives its power from a standard Power Over Ethernet (PoE+) switch (typical) or injector.
The radio node is fully compliant with the IEEE 802.3at PoE+ specification.
Per IEEE 802.3at, use standard Cat 5e or better twisted-pair cable with a maximum length restriction of
100 meters (328 feet) for PoE+. This restriction minimizes power loss between the PoE+ power source
and the radio node.
When connecting the radio node to a PoE+ switch, ensure that the switch port is statically configured to
deliver minimum 25W of power.
Power is distributed over two pairs of the four available pairs in Cat 5e or better cables. The
radio node can accept power on either used or un-used pairs.
Some PoE switches may be factory configured to deliver lower power per port. If this is the
case change the configuration during installation.

Figure 9 Radio Node Locations
When possible, locate radio node units at least 6 meters (20 feet) from an external wall. This distance
maximizes indoor coverage and minimizes RF leakage outside the building. Refer to the E-RAN
Deployment Planning Guide for Dual-Mode Systems and E-RAN Deployment Planning Guide for LTE
Systems for more information about radio node placement.
When mounting near a wall or other obstruction, orient the mounting bracket such that the transmit
antenna faces towards the coverage area and faces away from the wall. Refer to Bracket Mounting and
Cabling Guidelines on page 14 for more information.
Installation and Mount Bracket Assembly
The radio node slides into one of two brackets for ceiling or wall mounting:
• a quarter-inch (0.64 centimeter) deep for cabling through a surface such as a wall or ceiling
• a 1.25 inch (3.18 centimeters) deep for exposed cabling along a hard surface such as brick or
cinder block
Bracket Mounting and Cabling Guidelines
Incorrectly cabling and mounting a radio node can result in crushed cables and loss of communications to
the unit. Follow these guidelines in cabling the radio node and mounting it on the bracket:
• Ensure that the cabling is properly routed and dressed.
• Ensure that the radio node is fully inserted into the mount bracket so that it locks into place and
is flush. A correctly installed cable should at no time during installation impede inserting the
radio node into the mount bracket.

Boot Sequence and Services Node Communication
On initial boot, the radio node performs the following boot sequence. When finished, all devices are
reachable. Figure 16 shows the radio node boot sequence:
Figure 16 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.
