2.7 Verication of Ethernet Status
1. Verify that the cable gland for any unused Power and/or Ethernet port remains plugged to ensure a weather-tight
enclosure.
2. Close the lid and hand tighten the M8 enclosure bolts. With the bolts rmly in place, use the 1/2" (13 mm) socket
to torque each between 44.3 – 48.7 in-lbs (5 – 5.5 Nm) following the order of the numbers on the enclosure.

A seventh bolt is available as an optional Alpha security bolt (Alpha p/n 647-189-13).
Torque the security bolt to 35 in-lbs (4 Nm). For cable gland replacements, contact tech support at 1-800-863-3364.
NOTICE:
The Ethernet (ETH) LED will remain o until a device is connected via an Ethernet cable and it establishes a
communications link. The LED will icker depending on the amount of trac (slow ickering = slight trac / fast
ickering = substantial trac). If there is no trac, the LED will stay solid green.
NOTICE:
Failure to properly install the sealing insert and nut could result in water intrusion into the enclosure.
CAUTION!
Normally, the body of the cable gland connected to the enclosure stays installed. However, if it gets removed,
apply silicone-based O-ring grease (Dow Corning
®
55 O-Ring, or equivalent) to the gasket surface that faces the
enclosure, and reinstall, torquing to 70 in-lbs (8 Nm).

3.0 Managing the BSC
3.1 Local Access – Web Interface
The AlphaGateway BSC provides embedded Ethernet communications, allowing the user to view and congure settings
via a web interface. The local management port (seen in the gure below) is used as a connection point between the
BSC and a PC’s Ethernet port. The Ethernet port on the BSC is a fully functional standard Ethernet port, capable of
providing all the functionality of any standard Ethernet connection.
To access the BSC’s web interface locally via a web browser, use the following procedure:
1. Connect an Ethernet cable (CAT5 or better) from the Local Management port to a laptop or similar device.
2. Open a web browser.
3. Enter the default IP address (192.168.100.1) of the BSC into the web browser’s address eld. The
BSC’s web interface will load.
4. If the page does not load, or if it is preferable to manually assign a static address, connect the unit from a host in
the network and change the settings by following the procedures (for the version of Windows used) shown in the
addendum, “Conguring a Static IP Address."
5. Once the system has connected to a valid IP address, the user interface will load. From the screen below, scroll
through the rest of the interface to view the various operational parameters.

3.2 Remote Access – Web Interface
To access the BSC’s web interface remotely via web browser, use the following procedure:
1. Connect the laptop or computer’s network interface port to the company’s Ethernet network.
2. Open a web browser.
3. Enter the DHCP designated IP address into the web browser’s address eld (Use square brackets when entering
IPv6 addresses: [FC00:168:40::124]).
4. The BSC web page will load.
3.3 Navigation – Web Interface
The information screen oers a brief summary of the primary elements of the BSC. Detailed system information is
viewed by scrolling through the succeeding screens.
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 Tech Support to obtain the supported MIBs.
NOTICE:
