GPOE-4A INSTALLATION MANUAL

Welcome to the PoE Texas Manual for the GPOE-4A that cost effectively upgrades any non-PoE switch or PoE switch to 30 watt passive PoE!

The purpose of the manual is to help you quickly and effectively navigate the installation and functions of your new Power Over Ethernet Midspan. 

Our goal is to make our products as intuitive and simple to use as possible, so we value your feedback and questions directly to us at service@poetexas.com.  Phone +1-512-479-0317.

General Installation

A midspan like the GPOE-4A is a simple device to add into any network, and the purpose is to add or increase the PoE of your network without having to upgrade or pick a less optimal switch.

 

With this wall mounted device, simply mount it near the networking switch you’d like to pair it with.  Then, using a short Ethernet patch cable from the switch’s data port to the LAN port on the PoE midspan.   Then the POE port adjacent to the LAN port will now have that 30 watt potential power budget.

NOTE: a midspan adds PoE to one data port at a time.  So if you connect LAN 1 to a data port on your switch you’ll have Mode A POE on port 1 of the midspan [wait . . . what’s Mode A mean?].  To get POE on port 2, you need to add a patch cable on LAN 2 back to the switch,  And so on.

Then connect the POE port to your PoE enabled device.

WARNING: this is a passive PoE midspan, meaning it does not negotiate the IEEE 802.3af standard before delivering power.  What does that mean for you?  You should only connect the POE ports to a PoE enabled device.  Connecting it to a laptop or other non-PoE device will damage the network card on your device.

So why even use a passive PoE midspan?  Besides being very cost effective, they’re simple, robust devices that work well even when you forget about them.  So as long as the connected device is PoE and no one can unplug it – say a security camera or wifi access point – it makes sense.

CONFIGURATION

There is no configuration necessary with this device.  Simply plug it in.

The green LED indicates power on.   If the green light begins to blink at any time, it is an indication that one of the POE ports has shorted out or overloaded.

STEPS:

1 – Unplug the POE ports one at a time to determine which port is having the issue

2 – Troubleshoot the port to determine whether the cable or the device is grounded
