What’s Inside

PARTS LIST:

  • 1 X POE SWITCH
  • 1 X USER GUIDE
  • 1 X POWER CORD
  • 2 X RACK MOUNT BRACKETS
  • 8 X SCREWS (FOR RACK MOUNT)
  • 4 X RUBBER ADHESIVE FEET

General Installation

Your new PoE switch is designed to be simple to install and set up. You should only need at most a Philips head screw driver. To power it on, plug the power cable in the back.

Since this is an IEEE 802.3at (PoE+), you can just start plugging devices into it to eight PoE ports on the left hand side marked 1 through 24.

Ports 25S and 26S are for Small Form-factor Pluggable (SFP) fiber optic ports. There are two of them to allow you to create a self-healing ring network.  If you’re just using Ethernet, you can use ports 23 and 4 for the same purpose.

Desktop Installation

STEPS:

  1. Remove the adhesive backs from the rubber feet accessories and place them on the bottom of the housing in the square indentations for these
  2. Plug the switch into an outlet
  3. Start plugging in your PoE and non-PoE devices

*The rubber feet help the switch have the proper ventilation, so please don’t skip that step.
Yeah, it is that simple.

Rack Installations

The switch comes with brackets for a 19″ rack configuration.  Please contact us if you need a different rack.  It DOES NOT come with the nuts and screws to mount the switch onto the rack.  You’ll need to get those

STEPS:

  1. Using the 8 x small screws provided in the box, attach the two rack brackets to either side of the switch so that the brackets face the front as in the image above
  2. Using rack screws and nuts (not provided) mount the switch into the rack space (the switch will use 1u of rack space)
  3. Plug the switch into an outlet
  4. Start plugging in your PoE and non-PoE devices

Operating The LCD Screen

Main Display

When you plug in the PoE switch, it will automatically boot up to the PoE Texas screen. Then, the main monitoring screen will come up. This screen gives you a great heads up display on the PoE situation with the whole switch.

So why make a PoE switch with a display like this rather than just a managed switch? We’re considering the smart building situations where networks and infrastructure aren’t always in place when you need to start installing and testing new PoE devices such as lighting, displays, or sensors. This display screen allows a user to see and manage the PoE on devices without having to have the full network installed and turned up.

So what does it all mean?

First Column: This identifies the port numbers, including the two uplink ports 9 and 10

Second Column: The power status of the port.  See guide to terms below.

Third Column: The entering data rate from the device used on the port (in Mbps)

Fourth Column: The exiting data rate from the device (in Mbps)

If the data rate turns red, then the port is exceeding its bandwidth settings.

PB: The maximum power available on the switch

TP: The current output power of the entire switch

PD: The number of powered devices connected to the switch

Norm: The switch configuration mode.

Options: (Norm – Normal switch; VLAN – All ports have their own VLAN; CCTV – CCTV camera set up.  See section on Menu item 1 Switch Mode)

What Do the Codes In Column 1 Mean?

—-W: Nothing is drawing power on this port
OLP: Over load protection has triggered on this port, meaning you device is drawing too much power for the port (see section on Port Power).
ULP: Under load protection has triggered on this port, meaning the device is drawing too little power to keep the PoE live on the port.
SCP: Short Circuit Protection, meaning the device or the cable connected to this port has short circuited. You’ll need to replace somethings.
OFF: When green or white, the port has been set to “off” in the settings
When red, the data rate used by this port exceeds the set max. If this happens 10 times in 1 hour, the port will power down to protect the switch and other devices.

Switch Bandwidth

Switch Bandwidth allows you to limit how much of the switch’s bandwidth a particular port can use.  Let’s say you’re worried some guy will mine crypto currency through this switch.  You can set the switch to alert you here that a single port is taking more bandwidth than the setting.

PD Type

PD Type gives you control to override the Powered Device negotiation on the switch.
  • Standard: Your devices will negotiate the type of PoE and the classification
  • Enhance: Regardless of the device negotiation, this setting allows the port to deliver up to AT power and the settings you put in the PSE Port Power
  • LegacyNot used very frequently, this allows the switch to negotiate with a capacitance tag Powered Device
Unless you have a specific application or some unusual devices, you’ll likely just keep it on Standard.

PD Alive

PD Alive lets you set up an automatic reboot function for a port. Let’s say you have a security camera on the port, and it stops communicating for whatever reason. This feature here allows the PoE switch to take over and reboot the port to see if the device will come back on.

Use the up and down arrows to navigate to the port you want to have this feature on. Press “Enter” until the “Disable” is green. Then, press “Up” or “Down” until you see “Enable”.

Then press “Enter” again to set up the Start Up time using the up/down buttons: how long in seconds the device should take to start up.

 

Then “Enter” again to set the Interval time using the up/down buttons: how long in seconds the switch should wait to see if the device comes back up again.

Then “Enter” one last time to set the PowerOff time using the up/down bottons: how long it should stay off when it turns off.

When you’re done, use the “Back” button multiple times to exit to the main menu.

PSE Power Fine

PSE Power Fine allows you to adjust the residual power output of the ports so they can output more power as long as you have enough Total Power Budget (TB). This is used in some specific applications where you know your devices are riding right at the 25 watt limits of PoE+, say with a PTZ camera or a large Wifi access point (some of the high performance Cisco WAP’s fall into this category if their USB ports are turned on).

Depending on your situation you can add 5%, 10%, and 15% to the Power Budget (PB).

Use the up and down arrow buttons to select the option preferred, then use the “Enter” button to select it.  When the < is next to the setting and green, your option is selected.  “Back” out to the main menu.

PSE Port Priority

PSE Port Priority sets the priority for which ports will pull more power if the Power Budget (PB) of all the ports exceeds the Total Power Budget (TB) at any time.

Let’s say you have security cameras, phones, and wifi access points on your switch, and you’re right at the TB of the switch. If you want to make sure your security cameras stay live even if one of the wifi access points start to draw too much power, then the switch will prioritize the ports based on these settings.

By default, the lower number ports (1, 2, 3 . . . ) are higher priority. If you set both ports 1 and 2 at “High” priority, then port 1 will prioritize over port 2 in case of a conflict.

With the port numbers highlighted green, use the up and down buttons to select the port number.  Select “Enter”.  Then, use the up and down buttons to select the priority.  You have selected one when it is green and has the < next to is.  Then “Back” to the main menu.

PSE Port Enable give you the control to be able to turn on and off the power on any port. This ideal for infrastructure or IOT situations where the network may not be turned up for some time but the devices need to be installed, powered on, and tested during installation.

With the port number green, use the up and down buttons to select a port number. Then, press “Enter”. Use the up and down buttons until the “Enable” or “Disable” is green. Then press enter.

“Back” to the main menu.

PSE Port Power

PSE Port Power gives you control of whether a port can run at higher power than the traditional PoE standard. For example, you have a Thinlabs all-in-one PoE computer that you know you’ll use hard and add a lot of USB devices to. Rather than worry about your power budget, you can increase your power limit all the way up to 36 watts. Or, if you know your device will be small and you want to save on your PB, you can set the power consumption as low as 2 watts.

As before, while the port number is green, use the up and down buttons to select a port. Then press “Enter”. With the power green, use the up and down arrows to set the power limit on the port. “Back” to the main menu.

Note: This function is different from the PSE Power Fine function because that sets the fine auto adjustments, while PSE Port Power lets you set the big ranges.

In order to take full advantage of the PSE Port Power feature, you need to make sure the switch is set to “Enhanced” on the PD Type menu.  Otherwise you’ll receive this error.

LCD On/Off

LCD ON/OFF gives you control over how long the LCD screen will remain active after the last use.

Simply use the up and down buttons to select your setting, then press “Enter”. The selected setting will turn green and be immediately ready to use. Press “Back” to get to the main menu.

Fan Control

Fan Control gives you control of when the cooling fans will turn on. It’s based on the percent of the Power Budget (PB) used at the time. This allows you to keep the switch quiet until heat demands force it on.

Caution, though, setting the value too high in a warm environment like a packed server rack could allow the switch to go above the rated temperature limits.

Simply use the up and down buttons to select your setting, then press “Enter”. The selected setting will turn green and be immediately ready to use. Press “Back” to get to the main menu.

Language

You can select your Language on this menu.  Currently, Chinese and English are available.  Other languages can be added by request.

Simply use the up and down buttons to select your setting, then press “Enter”.  The selected setting will turn green and be immediately ready to use.  Press “Back” to get to the main menu.

Default Setting

DEFAULT SETTING restores the switch to factory default settings.  

Simply use the up and down buttons to select “Confirm”, then press “Enter”.  The selected setting will turn green and be immediately ready to use.  Press “Back” to get to the main menu.
