Welcome to the PoE Texas Manual for the GBTS-10-8-M-V2!

The purpose of the manual is to help you quickly and effectively navigate the installation and functions of your new 8 port IEEE 802.3bt PoE switch designed for Intelligent Lighting and Automation distributed networks

Our goal is to make our products as intuitive and simple to use as possible.  We value your feedback and questions.  You can reach us directly at service@poetexas.com and +1-512-479-0317.

Or you’re always welcome to leave questions or comments on our product pages: GBTS-10-8-M-V2

What’s Inside


  • 1 X PoE Switch
  • 1 X Wall Mount Kit
  • 1 X DIN rail Mount Kit – Does not include DIN rail
  • 1 X DC Power Connector
  • 1 X Relay Power Connector

NOTE: The switch is not Plenum rated per se so PoE Texas kit the switch in a NEMA rated enclosure for mounting in plenum spaces or areas not secured behind a locked door.



To deploy your new IEEE 802.3bt DC powered switch, you really only need three key things:

  1. DC power – 42-58 Volts DC, though we recommend 53 volts or higher for Lighting and Automation projects.
  2. Gigabit Uplink Data on the Small Form-Factor Pluggable Fibers slot
  3. Space:
  • Wall Mounted: 6.75″ x  4.5″ (included wall mounting brackets)
  • DIN Rail: 6.5″ x 3.5″ (included DIN rail bracket)
  • NEMA Enclosure: 12″ x 10″ x 6″ (Enclosure Accessory)

Mounting hardware like screws or wall anchors not included.

Key note:

  • Per UL/IEC 62368-1 Clause F.4, this equipment is intended for use only in a restricted access area.

That’s it!  Let’s get it mounted, then discuss how to configure it.  

About the Power Supply

The GBTS-10-8-M is designed to take 48-58 volt DC power.  You’ll notice there are two (V1-V2) input power points on the side. Additionally, there is an In (-) and In (+). When wired to the DENT-LINC as an input it can be used for brownout detection (see diagrams below).

These screw down terminal sockets have are rated for 14 AWG wire.  We recommend crimp on ferrules to make inserting and removing the cable easier.

The PS-53v3000w power supply designed to operate with this switch comes with interconnecting cables.  You can calculate the correct cable gauge for  your application at the correct distance using our Voltage Drop Calculator.

If you have questions about how to wire your switch, you can speak to PoE Texas about your cable needs for your project. Additionally, we have installation examples here.


The GBTS-10-8-M will function perfectly as a basic IEEE 802.3bt switch for PoE lighting and automation without any configuring right out of the box.  For most basic networks, you do not need to configure the switch to operate.  It will power on, negotiate the 4 Pair PoE for automation, and forward on the right network traffic for a basic configuration.

However, if you need to configure the switch, you will need a fundamental understanding of networking to do more than a few key management items.  We won’t try to show you how to do all the possible Layer 2 configurations in this manual.  Please contact us if you’d like additional information on configuring Layer 2 settings.

We will cover some important features you can control such as turning on a PoE watchdog, monitoring the ports, and setting your IP address to match your network.

    Web Management


    The GBTS-28-24-M has a web-based management interface that can be accessed through any of the network ports on the switch.  Before you integrate it into your network, you will need to set the IP address to match your local network settings.

    To start the configuration you need directly connect a network port to a computer.  If you don’t have an ethernet port on your laptop, this works just fine with an ethernet to USB adapter.

    Then power on the injector using any 48-56 volt power supply.  The settings will remain in the device even if you power it off and power it on again.

    Now comes the techiest part of the process.  You will need to disconnect your computer from wifi and the internet.  I know this feels very dangerous, but it’s only for a moment.

    We show the instructions in the video to the left for a Windows computer.  If you need help doing this on a MAC, simply go to YouTube and search on setting an fixed IP address for a MAC.  Then use the IP address information I give below.

    In Windows, navigate to your Network and Sharing Center.  If you don’t know how to get there, simply click on the Window button on the bottom left and type “Network and Sharing Center”.

    When it comes up, you should see an ethernet connection.  If not, double check 1) you’re connected to the switch through an ethernet port, and 2) the switch is powered on.  Click on the ethernet connection.  It will bring up a dialog box.Click “Properties” on the bottom left.

    In the next dialog box, look in the middle for “Internet Protocol Version 4”.  Click on it, then click “Properties” in the bottom right.

    Fill out the fields just like this.

    Click: User the following IP address

    IP Address:

    Subnet Mask: Sets itself

    Default Gateway:


    Preferred DNS Server:

    Alternate DNS Server:

    Hit Okay to close this dialog, then Okay one more time.

    I’ve tried not hitting okay the second time, and I couldn’t get it to connect.  So, make sure it hit okay to close out the two dialogs.

    Finally, open a web browser and type in the URL Bar.

    The default username is: admin

    The default password is: admin

    You’re in!

    Configuration Settings

    As mentioned above, we’re not going to try to show you how to use all of the functions of a Layer 2 switch, in good part because most of the functions do not really apply to Automation and Lighting.  The video configuration guide shows you how to:

    • Quickly see the status of the ports
    • Log on to the switch
    • Change the basic configurations in terms of time, location, etc.
    • Add or change users
    • Enable/Disable communication to the switch
    • Set the time clock to a server
    • Create a backup configuration file
    • Change the basic IP address of the switch
    • Manage the PoE including setting the total power budget
    • Finally, set a PoE port watchdog to reboot any ports that lose communication
