Cisco DMP 4310 with standard power injector.

Hi,
I am trying to use a Cisco DMP 4310 with a standard power injector (PRJ3) but it seems that the DMP doesn't start.
I tried using the power injector with a phone and also with a wireless access point, it is working.
I also tried to plug the DMP to a POE switch, the dmp starts.
Is the DMP 4310 compliant with standard power injector ?
Thanks.

Hi,
It seems that the Power Injector delivers enought power but I will try with a PoE+ power injector. In the power injector's datasheet there is nothing about a 802.3af (standard for PoE) compliance so I will try with a compliant power injector. I will let you know if I found the answer.
Thanks.

DMP 4310 5.4 with LG display

Hi everyone,
We've got a problem with Cisco DMP 4310 (v. 5.4) and LG display 42WS50. We try to use "Display power on/off" commands via RS-232 but it doesn't work.
We tried built-in commands for Cisco_32N and also tried to create new system tasks with RS-232 hex codes 6b612030312030310d/
6b612030312030300d. Prior to sending these commands we enabled RS-232 control but nothing worked.
Does anyone know maybe there are some issues in new DMP's firmware version?

We've run into troubles with faulty RS232 cables. Many of our DMPs were wired, but they just weren't receiving commands.
You might want to try the NEC PDComms tool, which you can download from here:
http://www.necdisplay.com/support-and-services/pdcommstool/Overview
With it, you can send RS232 commands from your computer, and view any response from your device. Then you can trouble shoot, at least ruling out the possibility of a faulty peripheral.
We didn't have any trouble with the 4310 5.4 when we isolated our trouble down to bad cables.
Good luck!

Line Extension with Power Injector: yes or no?

the lenght of the lan segment between switch and access point is cca 150m.
my quiestion is:
can i solve this problem with inserting Power injector (AIR-PWRINJ3) between, so resulting shema would be:
AP--70m(PoE)--PowerInj--80m(normal LAN)--sw2950
is it Injector in the function of L2 switch or is it only injecting power into normal 100m limited segment?
thx for answer

I tried this before, did not work. I think it's passive.
You have to use a fiber(MM does the trick and it's cheap, you dont need really clean terminaison for 100baseFX, mecanical with do)
or put a hub somewere.

Aironet 1310, power injector and poe cable

Hello,
Can the power injector delivered with aironet 1310 be supplied by a PoE RJ45 cable rather than the traditionnel DC adapter?
The problem is, i thought Aironet 1310 was PoE. Which means it can be power supplied by a rj45 cable.
But, when i openned my brand new 1310 box, i realized that 1st, it needs that Power Injector to work and that 2nd, Power injector needs a power supply...
Usually when i buy a PoE access point, I just plug in my PoE rj45 cable and its power supplied :)
Anyway, i hope there's an issue for this because where the 1310 should be placed, there's only a PoE rj45 cable arriving.
Thanks in advance,
lachapelle

Hi lachapelle,
Sadly the 1310 cannot be powered by PoE ,but, the Power Injector can be up to 100 meters away from the unit.
Dual coaxial cable to run from the power injector to the 1300. See attached notes:

How can I create a folder on internal storage of DMP 4310?

Hi. I'm a junior engineer in Korea.
I have a question about DMP 4310 with creating a folder of internal storage.
I can acess the internal storage but, I cannot make a folder or file uploading.
I already checked about Access mode - read and write, and also DMP management - FTP Server On, and password too.
It's enable to read but, unable to make a file or a folder.
when It rejected my order, I saw a message on my screen like this.
"550 Create directory operation failed."
I searched this letters, but couldn't get any information to handle this issue except for showing of permision error message of linux.
now, I am begging for your kindness.
what am I suppose to do?

I checked my permission, and I got the result.
By the result, I cannot make any folders or files except for path of /usb_1/
So, I can upload file to /usb_1/ and play it. that's it.
self question, and self answer... so sad to less people to answer this DMS section...

Is switch HP V1910-24G ''JE006A compatible with cisco components such as power injector and cisco SFP

Hi everbody,
I need your hand for this case please :)
this is first time to design outdoor AP, i will use 1532E due to the price is good, but my question is
* switch HP V1910-24G ''JE006A'' could be compatible with AIR-PWRINJ-30= & SFP cisco 1 G "glc-sx-mmd"
I am looking for your advice

the power injector will work but the cisco sfp will not work with the HP switch, also i recommend a switch that is already delivering POE+

Power injector with SPA508g

I decided to edit this since it got moved to a different place where it might not be understood:
I have a UC320w phone system. I have SPA508g phones. I have a cisco POE switch next to the UC320. But, I have one far location that has one ethernet port and we want 3 computers and the SPA508g phone. I don't have a POE switch and I'd prefer to put the switch before the phone. (the out port on the phone is 10/100 where I'd like the link to the far switch to be gigabit).
The SPA508g didn't come with power cords. I know I can get them.
But I happen to have an Aironet 1200 access point power enjector: AIR-PSINJSYS1200. I think the aironet needs 48 volts, so I assume this power injector provides that (or up to that?).
Is that ok to use this power injector with a SPA508g? Will it just draw whatever it needs or is that power enjector too much power? I seem some documentation that says the AIR-PSINJSYS1200 will work with a access point that requires less power, but I don't see any other documentation.

Unfortunately this is the wrong area of the community to pose the question. While I believe the aironet power injectors present a standard IEEE PoE interface to the device, I can say that for certain. Certainly those power injectors are only supported for use with the Access Points, and the people who hang on on this community are unlikely to be familiar enough with the product to say for sure whether it will work. If the injector does present an IEEE PoE interface then the phone should work fine, but I can't confirm that for you. You might want to try posting a question to the wireless forum at

Cisco Power Injector - AIR-PWRINJ4

                   Hi there, I have a quick question about Cisco Power Injector.
                    we bought a number of Air-PWRINJ4 year ago, mainly for extending the power via Cat5 ethernet cable to AP 1225 in warehouse. the output is 56V 0.55A.
                    Now I have a couple of spare left, my quesiton is if it is OK to directly power 3502I AP, which requires imput 48V and .35A. from the bag of Air-PWRINJ4, it indecates that the 3500 series is also included.

HI Scott, thanks for the reply, I have tested it works fine, but what will happen if we plan to use it for long run, does it will demage the APs?    in the packaging bag it says: Power Injector - AP 1140/1250/1260/3500 Series - SPARE
on the site I am setting up the AP, there is no POE switch and I don't have adapter with exact output for APs.

Power injectors don't work with APs

Has someone got experience on cisco power injectors for Aironet APs.
I bought 3 injectors, and 3 power supplys(injectors need power supply, but don't come with the boxes) from cisco.
I connected a switch(2960) port to the port ‘to network’ on the power injector, and connected a AP(1142N) Ethernet port to the port ‘to Device’ on the power injector.
The power injector was powered on by the DC supply. But the AP couldn't be powered on by the injector, and the switch port also showed 'noconnect'.
No particular commands setup on the switch port’s settings. I tried the switch port auto-auto and 100-full, Vlan access and trunk, but no luck with the injectors.
Connected the same power supply to the same AP, used the same switch port and same cables, the AP worked fine with the switch.
Thought of faulty injector, but it's weird that all 3 new purchased injectors are faulty.
Am I doing anything wrong? do I need to put any commad on switch interface to use power injector?(I cannot believe that) or just had bad luck of having 3 faulty injectors?
Please help. Thanks a lot.

Help with understanding the show power-injector comand

I have been battling a connectivity issue between my point to point 1300 bridges. The install is new and the distance between them is about 1881’. There is no LOS problem. I wasn’t sure if it was a power issue ie. the bridge not getting enough power so I issued the show power-injector command. What I find interesting is the difference between up interfaces. The near side bridge shows interface 4 up, were the far side bridge shows interface 4 down. I have read in the documentation, that interface 2-6 should be down, but why is the near side interface 4 up? Would this be causing my connection to be dropping? Are there any major areas of configuration I should be focusing on? The output drops on both radios are high and continue to increment. Any help would be greatly appreciated.

Hi,
Actually port on the power injector switch are in auto-duplex and auto-speed mode
you need to ensure external devices which you connected to power injector switch ports are not hardcoded in full-duplex, they needed to be in auto-duplex mode.
because in result of duplex mismatch you connection could be slow down and even ports may shutdown.
and also check both bridge with the latest firmware release
Cisco Aironet equipment operates best when you load all components with the latest version of the software.
You can download the latest software and drivers from the Wireless Downloads Page ( registered customers only) .

DMP 4310 load swf with flashvars

Hi,
I am using dmp 4310 and i want to load a swf file using flashvars. This swf is loaded through another swf (a wrapper swf) with the "MovieClip Loader Object" (AS2). When i load the swf using http request i do not have any prblems (eg clipLoader.loadMovie("http://10.0.0.1/swfTest.swf?flashVar1=test1")). The problem is that i cannot get the flashvars by loading the same swf file locally (eg clipLoader.loadMovie("file:///tmp/ftproot/usb_1/files/swfTest.swf?flashVar1=test1")). Is there any way to get the flashvar? Also, is there any way to access the swf file (with the flashvars) using the internal http service (eg http://localhost/...swfTest.swf?flasvar1=test1 -- where localhost is the player itself).
Thank you in advance for your response!

Suddenly that code in the following gives me some error
var langPath = root.LoaderInfo.parameters["xmlFilePath"]+root.LoaderInfo.parameters["lang"];
my_ssp.xmlFilePath = langPath;
var fileType = root.LoaderInfo.parameters["xmlFileType"];
my_ssp.xmlFileType = fileType;
Access of possibly undefined property LoaderInfo through a reference with static type flash.display:DisplayObject.
The only code snippet works is
var paramObj:Object = LoaderInfo(this.root.loaderInfo).parameters;
for (var param in paramObj) {
   if (param == "xmlFilePath") {
      my_ssp.xmlFilePath = paramObj[param];
   if (param == "xmlFileType") {
      my_ssp.xmlFileType = paramObj[param];

DMP 4310 display autodetection failed

Dear All,
We currently test DMP 4310G to display digital signage to displays, but somehow HDMI autodetection failed on most of the displays.
We have LCD NEC, Samsung, EX90, and CTS500 as display.
When we connect DMP4310 via HDMI to NEC, Samsung and CTS500, they just blank (even the boot page where IP address is usually shown).
DMPDM shows that the autodetection is failed.
But when we connect DMP4310 to EX90, it can display content perfectly.
I tried to disable autodetection and enter resolution manually ( i checked the datasheet for native resolution of each display ) but still no results.
I also find this document on Cisco:
DMP 4310G Notice Regarding HDMI/DVI Effects on Autodetection
A corner case exists that is mildly disruptive. It is not likely to affect your organization. To understand
this corner case, assume that all of the following statements are true simultaneously.
• Your DMP model is 4310G.
• Your presentation system’s media signal interface is DVI, not HDMI.
• EDID data in the firmware for your presentation system misrepresents its native resolution.
• The falsely claimed resolution is an HDMIstandard instead ofa VESA standard.
In this case, your DMP 4310G proceeds as if the native resolution is low, to ensure that your digital sign
shows anything at all.
Any comments are really appreciated
Best Regard
Imad

We've run into troubles with faulty RS232 cables. Many of our DMPs were wired, but they just weren't receiving commands.
You might want to try the NEC PDComms tool, which you can download from here:
http://www.necdisplay.com/support-and-services/pdcommstool/Overview
With it, you can send RS232 commands from your computer, and view any response from your device. Then you can trouble shoot, at least ruling out the possibility of a faulty peripheral.
We didn't have any trouble with the 4310 5.4 when we isolated our trouble down to bad cables.
Good luck!

Can not find Power Injector for wap2000.

Hello everybody.
Not long ago i was bought Cisco wap2000 access point for small business, and now the problem is to find power injector for this device.
I am already tried to use AIR-PWRINJ3, but access point did't turn on.
Why?
Which power injector should i use with this device?
Thanks.
PS.
Please, don't judge me, for my bad english. =)

I would think that:

should work, Cisco should be able to confirm . . .
If not then I would try:
