Re: Dc Injector Dll Download

I bought a Ubiquiti 802.3at injector ( -accessories-poe-injectors/products/u-poe-at) but it only puts out 48V... so the AP is running in reduced power mode. Netgear support says the Ubiquiti injector isn't actually AT compliant because the AT standard is 50V+ (they seem to be correct!).
Additionally, it's worth noting that POE injectors are PASSIVE (a little known fact), so even if your switch is only 802.3af 15W, if the injector senses ANY POE power on the non-powered line, it will pass on whatever PoE it detects on to the powered port, and will not 'inject' it's own power (whatever it supports).
Can I use any POE injector for the EAP225? (As long as it has the necessary wattage, of course, but the specs say it's 802.3af so I assume any injector should work.) Also (total noob question) are there limitations as to where the injector needs to be placed relative to the switch and/or the AP? To put it another way, if I wanted to, could the injector be placed near the switch with a 50 foot cable running to the AP? Or does the injector need to be placed closer to the AP?
However (and this is also mentioned in the linked FAQ), this does not apply to TP-Link EAPs that come with a passive PoE injector (such as the EAP225 V3) - while it says they are 802.3af-compliant, they only accept one of two possible PoE wiring pinouts (mode B according to the FAQ). PoE power sourcing equipment (PSE) such as an injector or a PoE switch can be either mode A or mode B (or have different pinouts on different ports), and powered devices (PD) must accept both pinouts according to the standard. However this is not the case for "hybrid" devices from TP-Link (and other suppliers) - so you need to make sure your power sourcing equipment provides the required mode. Don't ask how I found out about the different modes :).
The SIM Injector is simply a remote simcard hosting device, so the functions you are asking about are not going to be configurable within the SIM Injector. The functions you are asking about can only be configured within the celluler router/modem settings of the system requsting access to the remote SIM.
Hello Tim, @tgorter
Many guides in the forum and done by members who are enthoutiests for the products, this way the guides are compiled on real world experience by those out in the field. Let us see if we can get a fresh guide together for everyone.
The new firmware mentioned by Dennis @dennis.hofheinz is certianlly worth using is using for the SIM Injector. Any new guides done will be based on the latest Firmware Versions. We admire your persistance and the comunity here will continue to help you where we can.
i.e. I have selected 2 SIM slots of the SIM injector to be dedicated to a modem (entered on separate lines as given in some note somewhere, but when you go back is shown in a single line). but how are they treated by the modem?
I am used to the granular control within the MAX Transit line of products, where you can set signal thresholds, bandwidth maximums, and other settings which would force a SIM change if one of those rules were hit.
Does the HD1/HD2 Dome honor those settings? In my testing, it does not seem to honor the signal level, and I have no idea how it would know the bandwidth amounts since that UI appears to be only for local SIMs.
I agree. The POE device would be powered directly by the injector and not the switch. Think of it this way, when you plug in a computer or any other non-poe device into a poe port on a switch, does the switch go ahead and send power to the device? Nope because it knows the device does not need any power.
Most of the PoE injectors from UBNT (and possibly other manufacturers) are Mode B injectors, so if you have a device that only takes Mode A power (pairs 1-2 and 3-6), it cannot be powered by a Mode B injector that has power on the 4-5 and 7-8 pairs. I never have encountered a switch that used Mode B.
A PoE injector connects your PoE-enabled network device to a non-PoE LAN switch port.More specifically, a PoE injector can be used to connect a wireless access point, IP phone, network camera or any IEEE 802.3af/at-powered device (PD) to a network...
A parent instance (x calls up) does inject these dependences and as a solution I could pass them along, but I feel there must be a more elegant solution to this. So my actual question is: Is there a way in Play 2.8 to retrieve the injector instance that is used by the application?
Maybe I am missing something very simple, I am rather new to Play and Guice DI, so any help would be greatly appreciated. All the solutions that I found online refer to older versions of play, which do allow direct access to the injector or application objects. The examples from play 2.8 also show how to retrieve the injector, but only in the context of (unit) testing. Also, it is written primarily in Java, rather than Scala.
I see, thank you for the advice and for confirming that indeed @Inject is not an option since the class is instanciated outside of the injection mechanisms. Which makes sense, as the previous developers used:
If you use the injectors., they can be either at the AP and therefore vulnerable to being unplugged, or in the switch cabinet to keep them protected from interference. If in the cabinet, might as well use a switch!
switch when ever possible more control less points of failure. We have a device that is POE but we had to use the injector due to lack of POE and every time we have to reboot that thing its a trip to that IDF and pull the power wait and plug it back in. It is a hassle.
You're using the inject function wrong. As the documentation states, the inject function already instantiates a new instance of $injector. My guess is that by passing $injector as a argument to the inject function you are asking it to instantiate the $injector service twice.
One other thing to note. The argument authorService passed to the inject function has been wrapped with '_' so it's name does not hide the variable created within the describe function. Thats also documented in the inject documentation.
>> binding commands will make other features like overriding bindings
trivial to implementThis is probably not yet available - unless you create new Injector?Injector injector = Guice.createInjector(rewrittenModule);
assertEquals(new Pepsi(), injector.getInstance(Soda.class));Will this help with unbinding as well?
e.g. I have a huge state machine where services come and go, meaning I
would still like to use Guice to handle my binding, but not for the cost
of class leakage - unless Class --> Provider mapping is weak, meaning
once I remove class's classloader that binding goes away as well?Cheers,
Alesbtw: are Commands available in Maven2 repo?
I'm using this in the new JBoss5 kernel.
Imagine having a single Injector at the AS's bootstrap.
And then different apps come and go, and they can register new bindings
making its beans/services available to Guice.I do control the service lifecycle together with its classloader, but if
I cannot remove the binding, probably leaves me with a leakage?OK, I guess I could do things differently, creating Injector per
classloader, and use some sort of hierarchy of Injectors (already exists
afaik), the root being the one at bootstrap.- Ales
Mazzei venturi injectors are differential pressure injectors with internal mixing vanes. The unique, patented design of Mazzei injectors maximizes injector efficiency, suction capacity and mixing capabilities. Our injectors also have no moving parts, which simplifies maintenance, and they have much lower operating costs than less efficient systems.

The layout will be very linear - basically APs all in-a-line above the track. The only common point will be in the center which will be well over 100m from the ends. The APs will be mounted high so vandalism shouldn't be too much of an issue but it is something good to consider. Thank you
You can't use a PoE injector to extend the maximum range of Ethernet (which is 100m). If the overall length of the Ethernet is over 100m with a PoE injector in the middle, you are likely to run into reliability problems (or it won't work at all).
If you could run a fibre to a central location and then run 2 or 3 APs copper cabled back to that location, an MS120-8LP will likely give a better solution (and involved a lot less parts). It just doesn't stack up so well if you can only cable a single AP back to where the fibre would terminate.
I have an EnGenius EAP350 Access Point that supports 802.3af PoE. After digging through the specs sheets online, I believe that the AP requires [email protected] when using POE. Currently I have the AP running directly on a power adapter, however I'd like to move it to a ceiling mount in the middle of the house. So far I haven't been able to find any mention of supported PoE injector models for this AP on the EnGenius website. When I called their technical support, I asked the person about whether or not this AP supports mesh and which types of POE injectors were supported. The support person just stammered on about how their new products had so many more better features and told me the only way to use PoE for the AP was to use a PoE compatible switch.
So here I am asking you all if anyone knows the difference between PoE injectors that are 802.3af compliant, but some say Gigabit and others say only 10/100. According to the Wikipedia page on PoE, the power pinouts for 10/100 and 10/100/1000 appear to be the same; Using pins 3,4,7, and 8 for power. I know that the physical difference for 10/100 and 10/100/1000 is that the for gigabit, all eight pins are utilized in the cable for bi-directional communication whereas in 10/100 only 4 pins are utilized.
