Welcome to the PoE Texas Manual for the GBTS-28-24-M!
The purpose of the manual is to help you quickly and effectively navigate the installation and functions of your new 24 port IEEE 802.3bt PoE switch designed for Intelligent Lighting and Automation.
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 email@example.com and +1-512-479-0317.
Or you’re always welcome to leave questions or comments on our product pages: GBTS-28-24-M
- 1 X PoE Switch
- 1 X Rack Mount Kit – Does NOT include the rack nuts and bolts!
NOTE: The switch includes the screws for the rack wings, but it does not include the rack mounting nuts or screws. So, you’ll want to grab some of those.
You will want to have patch cables and potential some ferrule connectors for the power cables on hand if you’re not using the cables supplied with our PS-53v3000w power rectifier.
You have everything you need to get your switch up and operating. Let’s get started.
To deploy your new IEEE 802.3bt DC powered switch, you really only need three key things:
- DC power – 42-58 Volts DC, though we recommend 53 volts or higher for Lighting and Automation projects.
- Gigabit Uplink Data on the RJ45 port or Small Form-Factor Pluggable Fibers slot
- 1 unit of 19″ rack space
- 17 1/2″ wide by 9 1/2″ long desk space
* Optional: If you’re rack mounting it, you do need nuts and bolts to mount it on the rack.
- 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.
Put it together:
About the Power Supply
The GBTS-28-24-M is designed to take 48-58 volt DC power. You’ll notice there are two input power points on the back.
The switch operates at maximum power output when both terminals are connected to the power supply.
These push-in terminal sockets have a 22.5 amp limit and are rated for 10 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 use 1 x set of 12 gauge wire to power up to 1080 watts. As you go up above 1080 watts in total power draw, you will need to use the second power port or V2.
If you have specific cable needs beyond the included interconnecting cables, you can speak to PoE Texas about your cable needs for your project.
HOW DO I KNOW HOW BIG MY POWER SUPPLY SHOULD BE?
You can use our PoE calculator to quickly calculate your expected load on the PoE injector.

WIRING DIAGRAMS FOR
GBTS-28-24-M AND PS-53V3000W POWER RECTIFIER
The GBTS-28-24-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.
CONNECTING TO THE CONSOLE
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: 192.168.0.10
Subnet Mask: Sets itself
Default Gateway: 192.168.0.5
Preferred DNS Server: 126.96.36.199
Alternate DNS Server: 188.8.131.52
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 192.168.0.1 in the URL Bar.

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
