Switch P 52 SG500 - web interface shows the wrong model and disconnects randomly

Ladies and gentlemen!

One of our network switches is a SG500 switch 52p that recently started showing strange behavior.

It started with the problem was not more accessible via its web interface. Even if it was running perfectly well access via a web browser finished in wait times.

After resetting the factory default switch and configure its IP address access at first seemed to work but I had to know that the switch breaks out as a SG300 28 p switch on the administration Web site. In addition, random logoff occurs that send back me to the login page. Each from time to time, the model is correctly displayed after the login, but when I try to manage it I a connected again.

It still works with an older version of the firmware (1.2.xx I think) but that shouldn't cause such behavior, it should? In any case, I can't update the firmware says the switch as a different model.

Any suggestions what to do (apart from the RMA)?

Respect,

Hendryk

Hello

I'm sorry that you are having problems with the device and I'll try to give you the best possible advice in the circumstances.

The first thing that comes to mind is that you connect to another device, the thought is the SG500. I did the experiment several times before, so I have a few suggestions to ensure we are connection to the device:

1 - Download the Cisco FINDIT and scan tool you rnetwork, maybe you will find that you have two devices, the SG300 and the SG500. Here is the link:

https://software.Cisco.com/download/release.html?mdfid=282833583&flowid=...

2 - go to the switch that you believe to be the SG500, then go to Administration, and then discovered - CDP, and then click CDP neighbor information. Most likely, you will see that you have several switches, including the SG500.

3. If you have followed suggestions and you still believe, you go to the right switch then call at the 866-606-1866 (of the United States) and we will be happy to help you control the device and replace it if this is the case.

I really think that the first 2 suggestions will help you realize that you have two switches on your network.

Please let us know what you find.

  • Problems to show the driver IVI and property loader error messages when you use a type of operator interface

    I use UI operator (programmed in ICB, with asynchronous timer) in the folder OP1 in attached zip file. This operator interface does not have the error message from the driver of the IVI, properts, charger etc. on the screen (messages as in the photo attached error.jpg in zip file attached). Due to stability problems, I use this operator interface, but I need these error message. One other operator interface is OP2 in attached zip file. This operator interface puts the error message from the driver of the IVI, charger properts... on the screen (messages as in the photo attached error.jpg in zip file attached). Now, I want to have this feature with OP1 for reasons of stability I use OP1. How can I implement this in OP1? I tried and tried a lot of time, but I have not found a method to implement this. can someone help me? Thank you kind regards Samuel

    Hello, Johann,.

    I'm not sure you understood my problem. My problems are not the IVI and loader drivers error messages property! But my problem is, that errors of the IVI drivers and property loader operator interface does not bring on the screen. So to test this situation, cause an error of the driver of the IVI or shipper of property, then you can see that with a PC, you have an error message and with another IO no error message takes place and the test of stocks without a message. Do you know why this OI does not show the error messages and how showing the error message can be implemented in this operator interface

  • I can't connect to my mac because the SHIFT key is down. Then he showed the top letter and can not connect... The mac is also overheating. I went to the apple store and they said that they cannot fix and need to send to the factory. Connection of same slo

    I just used my mac. I bought it on January 2014.

    A few months ago I couldn't connect to my mac more. There is nothing special on my mac to record.

    He was showing the wrong password when I tried to connect to my mac. It is overheating sometimes without help.

    So, I brought it to the apple store and they said that the shift key is down and therefore superior letter is all the time. and they could not help me open on the inside. Apple store guys suggested me to display somewhere or send it to the factory.

    My question is

    (1) what should I do

    (2) if I send to the factory or should go to the repair shop.

    you guys have an idea what the problem with my mac?

    I suggest you send to the factory, or if you have an apple authorized dealer / repair shop to fix the SHIFT key first, then a glance as to why the fan is still running hot.

    Maybe something has damaged the keyboard (shift key) area and also the fan internal.

    You can't have something special on the computer, but I'd always spend extra money to repair.

    The sooner, the better.

    take the cos(pi/2) shows the wrong result in swift but when I take the sin(pi/2) it shows the correct result.

    I'm messing around with math to swift before that I use it in my application but I'm having a problem to calculate the correct results with cos at 90 degrees, pi/2 radians and 270 degrees, 3Pi/2 radians.

    the results I get for cos(pi/2) are 6.123233995736766e - 17 when I know that it must be equal to zero...

    the same thing happens as well with the seizure of the sin (pi), sin (0), the sin (2 pi) and so on.

    6th-17 is zero! After all, you didn't feed it pi, but an approximation.

    The date and time settings would cause problems of synchronization with Eprint if incorrect. The date and time should be accessible from the Preferences menu.

    Try this

    Power reset

    1. Without putting off the product, disconnect the power cord from the back of the product.
    2. Wait 30 seconds and then plug the power cord into the back of the product.
    3. If the product is not already on, press the power button to turn it on.

    Now, try to change the date and time and check.

    Where this fails, try this

    Setup > tools > restore defaults

    Try to set the date and time of return

    NOTE: This will remove network also settings so you need to redo the configuration of the network

    phoechan,
    More than likely if this started after you upgrade to Windows7 then you might have to update your hardware drivers.  Go to the websites of the manufacturers of hardware for your PC and get all the latest drivers for Windows 7 (video, sound, chipset, etc...).  If they don't have Windows 7 drivers you may have questions until they create them.  You can also try to boot your PC and also right click on the game .exe file and change the compatibility mode to Vista or XP.

    I love the develop module, but I'm doing something wrong in the library

    In the library, under 'Catalogue, all the photographs', all my photos appear showing the stars, cropping, and development. The problem is that these changes are not for the photos on my hard drive. When I re-import them in Lr, the changes are not there. My workflow is to do nothing after development or export them to the original with a new file name destination. Anyway, it is that they get a new file name without change of development when they are imported into Lr.  Please help (PC user)

    And others have explained, Lightroom does not apply the changes to the file. All changes are stored in the catalog, and then applied to the image when it is displayed in Lightroom. If you want a copy of the image with any changes so that you can share with others or send it to a laboratory to print, then you must export a copy of this image by using the export dialog box in Lightroom.

    Features of Lightroom as well by its design. The images that you import are always left in their original condition, unmodified.
