® Alpha shall not be held liable for any damage or injury involving its enclosures, power supplies, generators, batteries or other hardware if used or operated in any manner or subject to any condition not consistent with its intended purpose or is installed or operated in an unapproved manner or improperly maintained.
System Grounding with Low Voltage Disconnect Switch in use: For installations utilizing Alpha Technologies’ optional low-voltage disconnect switch (Alpha p/n 021-111-20), use a #6 AWG wire to connect the ground lug on the baseplate of the switch to a driven ground rod in accordance with local electrical codes.
1.0 Introduction This guide addresses the identical installation and configuration of the following Alpha Broadband Small Cell (BSC) ® outdoor gateway models: • (Power only) AG300P-AC90, AG300P-AC120 • (Power + DOCSIS 3.1) AG300D-AC90, AG300D-AC120 ® Additional product specifications are included at the end of this document.
Set up a billing account (if applicable). • As appropriate, provision each connected device using the device’s MAC address. • The Alpha BSC outdoor gateway can also be connected to the hard coax through a directional coupler. ® NOTICE: • Each connected device will register as a distinct CPE device; these may need fixed IP addresses depending upon the model.
79.7–88.5 in-lb (9–10 Nm). 2. Take the two strand mount brackets [2] from the strand bracket installation kit (3" bracket kit, Alpha p/n 746-627-23 or 2" bracket kit, Alpha p/n 746-627-24), remove the two plugs from the top of the enclosure, and secure the mounting brackets in place.
79.7–88.5 in-lb (9–10 Nm). 2. Take the two strand mount brackets [2] from the strand bracket installation kit (Alpha p/n 746-627-23) and remove the two plugs from the top of the enclosure, securing the mounting brackets to the Alpha BSC outdoor gateway in their ®...
Fig. 2-5, Gateway Wall Mount Bracket Align the bracket (Alpha p/n 746-645-20) into the desired installation position on the wall. Mark the four holes where the 5/16" (M8) hex head screws will be drilled into the wall. 2. Drill four pilot holes into the wall using the wall mount bracket as a template. If mounting to drywall, a stud should be located and used to secure any two of the hex head screws.
Flat Washer Fig. 2-6, Pole Mount Installation Configuration Secure the pole mount bracket (part of Pole Mount Bracket set, Alpha p/n 746-861-20) to the pole using the metal straps. 2. In the top two mounting bracket holes of the Alpha BSC outdoor gateway, partially tighten two of the 1/4"-20 bolts,...
Installation, continued Connection and Start-Up Fig. 2-7, Connection Diagram HFC hardline coax (45-90VAC quasi-square wave + DOCSIS ® Directional coupler / splitter Ethernet port Input power (also RF signal for data backhaul) Strand-mounted BSC outdoor gateway AC outputs (up to 4) WARNING! ELECTRICAL HAZARD Low impedance grounding is mandatory for personnel safety and critical for the proper operation of the cable system.

Installation, continued Prior to applying power, ensure the unit is properly grounded as described in the Alpha Grounding System ® Installation Procedure on page 6. CAUTION! To protect the installer from working on a live unit, connect the coax cable to the BSC outdoor gateway first.
Ground 10. Verify the output indicator LED is illuminated, signifying Line Neutral power is present (applies to all four models of the Alpha BSC outdoor gateway). ® Underside of connector showing screw terminals Completed cable gland assembly Sealing insert...
This applies to the AG300D models. The Ethernet cable can be installed before or after start-up. Remove and disassemble the corresponding cable gland. See Fig. 2-9. 2. Route the Ethernet cable through the cable gland and into the Alpha BSC outdoor gateway.
Installation, continued Verification of Ethernet Status Once the Alpha BSC outdoor gateway is powered up, the power outputs will activate and the cable modem (CM) boot ® process will begin. Pre-provisioning phase (unit is not yet provisioned by the CMTS): •...
70 in-lb (8 Nm). NOTICE: A seventh bolt is available as an optional Alpha security bolt (Alpha p/n 647-189-13). Torque the security bolt to 35 in-lb (4 Nm). For cable gland replacements, contact tech support at +1 800-863-3364.
3.0 Managing the Alpha BSC Outdoor Gateway ® Local Access – Web Interface The Alpha BSC outdoor gateway provides embedded Ethernet communications, allowing the user to view and configure ® settings via a web interface. The local management port (seen in the figure below) is used as a connection point between the BSC outdoor gateway and a computer’s Ethernet port.
• For web server (HTTP) access, port 80 must not be blocked and the computer must have access to the private cable modem network. • The BSC supports SNMPv1, v2C and v3. Contact Alpha Technical Support to obtain the supported MIBs.
Managing the BSC, continued Upstream and Downstream RF Signal Power This screen provides data with regard to signal frequency and respective power level, (e.g.,603 Mhz, at -5.0 dBmv). Fig. 3-3, Upstream/Downstream RF Signal Power Screen (Sample) RF Attenuation Attenuation values for upstream/downstream signals can be applied and/or modified via this section. This adjusts the power level of the frequency’s signal.
Managing the BSC, continued OFDM Downstream / Upstream Data The DOCSIS 3.1 communications module in the Alpha BSC outdoor gateway utilizes orthogonal frequency-division ® ® multiplexing (OFDM) in order to encode data on multiple carrier frequencies. This method allows for increased transmission speed with the same frequency range.
