Receive optical power warning - above threshold

As we know,

We cannot set up the optical transmit power of the SFP. However, we can check the power level of reception received by the peer through the command:

View details transceiver interface

However, newspapers have been showing:

20 August 06:45:14.434: % SFF8472-5-THRESHOLD_VIOLATION: item in gi1/0/25: high power warning Rx; Running value:-1.7 dBm, threshold value:-3,0 dBm.

Check:

Optical alarm warn high low warn low alarm
Receive the power threshold threshold threshold threshold
Port (dBm) (dBm) (dBm) (dBm) (dBm)
-------    -----------------  ----------  ---------  ---------  ---------
Gi1/0/25-1 article, 7 + 1.0 - 3, 0 - 19.0 - 23.0

This will have a big impact on my switch? In particular the SFP

Factors such as damage, etc.

In addition, how will this affect the performance network, health and functioning of my devices

Your ideas are much appreciated (and if you can back it up with docs, it would be useful also! ^_^)

It seems that your remote line is the sending of a relatively high output power and/or you have a connection very short fiber with very little loss. Since you are only at the beach 'warning', you are not likely to damage any of the SFP receiver or adversely affect the operation of the network.  You don't have the possibility to add an Optical Attenuator on the link to make the action more within the specification range.

  • mobile broadband stick too big causing me not able to connect my wireless receiver optical mouse

    ACER dear community,

    I need your help or solutions. My problem is about my mobile broadband using stick and wireless optical mouse at the same time. I just bought a laptop Acer V13 and excited to use when I'm out and about. I have more access to public wifi and that's why I have this mobile broadband USB which I bought at my local service provider so that I can connect to the internet with it. This stick allows me to connect to the internet with a prepaid SIM in it. I'm sure you know what I describe about. I'm just explaining in detail. In any case, my stick is kinda huge. Then, when I plug in my USB port 1, I can't plug my mouse receiver into the other USB port wireless because the stick took so much space. I wish the USB ports were in separate locations, or at least a few inches on the other. Is there anyone out there who can give me suggestions or ideas on what to do? I know that this question is lame, but ideas and suggestions will really help me. Thank you very much!

    As mentioned above. I discovered that I can not use several hubs extension BUT... it works when you use usb single exntension. Managed to solve the problem and I finally can I plug my mouse wireless receiver so my stick mobile broadband. See photo!

  • Acquisition of data above threshold

    Hello

    I started with LabVIEW, a few days ago and found it quite difficult. Hope you can help me a bit.

    My task is: 2 channels (from acoustic sensors), I need to find the time of delay of arrival between them and then to calculate the coordinates of a source that emits sound waves. Then, I looked at several examples that I could find and finally I am stuck at the very beginning.

    I need to work with signals (impulses) are greater than a certain threshold, but how can I do this? I do use the Detector.vi threshold or not?

    Then I need to find the delay of arrival time. Use CrossCorrelation.vi?

    Thank you very much.

    OK, the data type of waveform coming from reading your original image is just the default output. You can also acquire the three channels in a single acquisition job by specifying several physical channels and change the output in a 2D DBL table format. In this form, the columns are different channels in your task of CQI. You can then treat each channel I described.

  • Has received a Trojan warning while accessing the Web site. Was - this legitimate?

    I was visiting "memory lane" when a warning popped up on Trojans.  I didn't know about the "fixit" downloading as my wife told me that a person might be hacking us.  Had to get out of the internet to access my Panda security.  The message "microsoft", said that she had detected 32 Trojan horses, however, Panda found 1.  Any info or were there problems with this type of warnings?

    first of all, it's a 'good' thing you do not fall into fear and then commit the patch program because it would have infected your system.

    These types of sites are known and exist everywhere on the internet.

    my suggestion is to install and run "searh spybot and destroy" and inoculate your system.  keep it updated regularly and run too regularly.

    the freeware will add hundreds of URL in the host file that are known to be dangerous and prevent anyone to visit them through the browser.

    with regard to panda.  I think it's ok.  the problem is that if we found a Trojan and removed, then you need to monitor the system and see if it keeps reappearing.

    If so, then it means that you have an apparently harmless program installed that is implement the Trojan horse on your system.

    Finally, since you haven't found an infection on your system so it can also be in hibernation in the system restore points.  so even if your system can finally get rid of the infection, it can be reinstalled if restore you a system infected restore point.

  • Warnings of power transceiver optics EEM

    I am wanting a script that will generate a message to syslog for alarms and warnings of power tx/rx combine.  I would like to use the 'inter radio show' command that generates output similar to the output below (see also the output file attached)

    switch6504 #show inter transceiver

    Note: A single hyphen after number is a warning and a double hyphen is an alarm

    I'm eager to EEM script to generate a message to syslog for the warning or alarm power tx/rx.  Two messages different syslog:

    (1) syslog = 'has $interface of an alarm of tx/rx optical power.

    (2) syslog = '$interface has a warning of tx/rx optical power.

    I am only concerned the tx/rx power.  I would like the script runs every 30 minutes. If there is a warning alarm / on an interface to send a syslog once every 24 hours, while the conditions are still met.

    I started the script (see attachment), and I'd appreciate any help.

  • Receiver "warning message" that the photos could not be found and that it will not be included, when sending emails with photos?

    Original title: How can I include pictures when I send an email?

    Sometimes when I receive an email with images embedded in the e-mail message, if I send the email, the text is passed, but where the photos were in the original message, there are empty spaces or perhaps some identification confusion of where a copy of the projected image can be kept (I think - not sure). Sometimes when that happens, I get a message "warning" that the photos could not lies and will not be included.

    I tried to paste a copy of the warning above - no luck with that either.

    HELP please.

    Hi Bill,

    1 are you facing the question with any specific email account?

    2. the problem occur only when you transfer emails with photos?

    3. What is your default browser?

    4. you see a red "X" instead of a picture on Web sites also?

    Some of the sent emails will not include images when you transfer them again. You can should forward the e-mail as an attachment or, save the images to your system first and then try to attach the photo and forward the message.

    You can also check with your email provider to see if there is an option for "include images with messages" that must be activated.

    Hope the helps of information. Let us know if you need help with Windows related issues. We will be happy to help you.

  • Hello, I receive a message telling me that my AC power adapter type cannot be accepted.

    A few days ago, I started having a power warning message when I turn on my laptop. It is said that the AC power adapter type cannot be determined. Beacause it my battery will not charge. But it's the power adapter that came with it and I have used for so long that I got the machine. Do not know what is happening.

    I guess that the laptop works on AC power only but always?

    If you remove the battery from the laptop work?   If yes then I suspect the battery does not have rather than the power adapter.
    If it will not work without the battery then I would suspect that the adapter is faulty/defective.
    Don't let not the battery-even if it is the problem.
  • Received an email from * is this legitimate?

    I therefore an email with an order ID that I did not, and this same order does not appear on this Web site nor it seems that its ID is legitimate... but when I googled the e-mail address which originated this order - *-I only get the legitimate results for apple, not only denouncing an illegitimate source. I think this is a phishing scam (or it can be also ransomware reason why I will not risk clicking on the apparently legitimate-looking email) - unless the address is indeed legitimate and in this case, someone posted somehow an order from my account without my authorization and which also does not appear on myorders.

    Someone has received emails from the above? Is it legitimate or not? Thank you

    < personal information under the direction of the host >

    Can you post the entire contents of the email (less direct personal information and deletion of the links)?

    It sounds very similar to a phishing scam. An email about an order that you never passed is very often, but not always, a scam. The address of e-mail may be legitimate, however, it can be misused and could not have been sent in fact from this address. If you think that it is a scam, you can send it to [email protected] , then delete it. But first, go to http://reportaproblem.apple.com and check to see if the so-called order appears here. If so, then the email is legitimate, and you can declare the purchase as not allowed in this Web page.

    You can see here to help with the identification of these emails and how to report them: avoid Phishing scams.

    (Note that I could receive some form of compensation, financial or otherwise, to my recommendation or a link, because certain parts of the site contain small banner ads).
