EnerSys AlphaGateway SMG-HP AG100D-PoE+ Quick Start Manual
Quick Start Guide, AlphaGateway SMG-HP, Model AG100D-PoE+
The AlphaGateway SMG-HP AG100D-PoE+ provides 2 x 10/100/1000 BASE-T Ethernet ports with support for IEEE802.3af/at PoE/PoE+, with a
power output of 30W per port. The included DOCSIS 3.1 cable modem provides power system status monitoring and up to 1 Gigabit connectivity.
The unit connects to the HFC Coaxial Access network through a power-passing tap at any location within the HFC voltage range (44–90Vac Quasi
Wave), and transforms the HFC power to a voltage suitable for connected devices.

NOTICE:
Each connected Ethernet device will register as a distinct CPE device; these may need xed IP addresses
depending upon the usage model.
Ensure that unused ports are covered with plugs. Remove only the plugs necessary for installation.
For other mounting options, refer to the SMG-HP Technical Manual (Alpha p/n 018-357-B0).
Pre-Installation
Tools Required (User-Supplied):
Torque Wrench with:
7/16" (11 mm) Socket
1/2" (13 mm) Socket
Open-ended 7/16" (11 mm) torque wrench
Flat blade screwdriver (to remove nylon screws during bracket installation)
SMG-HP Grounding
1. Locate the ground lug mounting location [1] and install the ground lug hardware as shown in Fig. 4. Tighten the
hex head nut to 44 in-lbs (5 Nm).

2. Properly ground the SMG-HP by connecting a #6 AWG wire from the grounding lug on the body of the unit to the
strand ground in accordance with local electrical codes. Apply anti-oxidant compound (e.g., Noalox® or equivalent)
to the ground connection. Bond the grounding system to other grounded electrical equipment located within 20 ft
using #6 AWG bonding conductor.

NOTICE:
Alpha Technologies Services, Inc. assumes no responsibility or liability for failure of the installer to comply with
the requirements of applicable local and national codes. Where allowed, exothermic welding may be used as an
alternative to compression grounding methodologies.
NOTICE:
Follow national, local and MSO/employer grounding standards.

1. Remove the two nylon screws from the top (or back, e.g., if hanging the SMG-HP horizontally) of the enclosure.
2. Take the two strand mount brackets from the strand bracket installation kit (3" bracket kit, Alpha p/n 746-627-25,
2.5" bracket kit, Alpha p/n 746-627-27 or 2" bracket kit, Alpha p/n 746-627-22), and attach the strand mounting
clamp hardware as shown in the stack-up below [2]. The clamp may be reversed to accommodate either 1/4" or
3/8" diameter strand. Repeat for the second bracket.
3. Verify the proper orientation as shown below and fasten the bracket with the hex head bolts, lock washers, and
at washers as shown in [3], torquing both brackets to 46 in-lbs (5.25 Nm).
4. Verify the clamp is oriented to t the strand and hang the SMG-HP on the strand torquing to 84 in-lbs (9.5 Nm).
Repeat for the second bracket.
NOTICE:
For installations of units in conned spaces (e.g., vault installations) the unit may be fastened to the steel mounting
rod via the hardware stack-up shown in item [4].
NOTICE:
When hung vertically, the SMG-HP must hang from the strand with the hinges facing down.
5. Properly ground the SMG-HP by connecting a #6 AWG wire from the ground lug mount to the strand ground per
local code. Apply anti-oxidant compound (e.g., Noalox® or equivalent) to the ground connection.
6. Refer to "Connection and Start-Up" and follow the procedures to connect, start-up and verify operation of the
SMG-HP.

This method is recommended for installations in areas with space limitations within the communications space between
poles, or when a connected application device (e.g., WiFi AP, camera) is mounted directly to the SMG-HP’s lid.
1. Remove the two nylon screws from the back of the enclosure.
2. Take the two strand mount brackets from the strand bracket installation kit (3" bracket kit, Alpha p/n 746-627-25,
2.5" bracket kit, Alpha p/n 746-627-27 or 2" bracket kit, Alpha p/n 746-627-22), and attach the strand mounting
clamp hardware as shown in the stack-up below [1]. The clamp may be reversed to accommodate either 1/4" or
3/8" diameter strand. Repeat for the second bracket.
3. Verify the proper orientation as shown below and fasten the bracket with the hex head bolts, lock washers, and
at washers as shown in [2], torquing both brackets to 46 in-lbs (5.25 Nm).
4. Verify the clamp is oriented to t the strand and hang the SMG-HP on the strand torquing to 84 in-lbs (9.5 Nm).
Repeat for the second bracket.
5. Properly ground the SMG-HP by connecting a #6 AWG wire from the ground lug mount to the strand ground per
local code. Apply anti-oxidant compound (e.g., Noalox® or equivalent) to the ground connection.
6. Refer to Section 2.4, "Connection and Start-Up" and follow the procedures to connect, start-up and verify
operation of the SMG-HP.
