GS728TP: PoE fault

• SG300 - 28 p: POE power drops every few minutes

  Hi all

  We have a SG300 - 28 p which, at intervals between 5 and 30 minutes or more, lower power to all its ports POE-powered and then immediately restores power. Switch logs nothing when this happens other than to record that the ports went down and back up, even with debug logging enabled. Non - POE ports are not affected.

  When the problem started there were only four POE devices on the switch and we are far under our power budget. (During the test, I added a fifth device, see below.)

  Not all combinations of devices cause the drops occur - specifically, it seems that having devices on ports next to each other causing the drops. When the drops occur, absent the increment of POE devices all counters. I noticed this thread earlier here seemed similar:

  https://supportforums.Cisco.com/thread/2165089

  but in this case, he got no power at all in the adjacent configurations, instead of having to drop all the several minutes.

  I am running

  SW06 #sh worm

  SW version 1.1.2.0 (November 12, 2011 time 23:34:26)

  Start the 1.1.0.6 version (date may 11, 2011 time 18:31)

  HW version V02

  I have the 1.2.2.7.6 ready to go new firmware, I will update this when I get a chance to test it. Unfortunately, it's a switch of production, but it's a with relatively few devices to it so far. If need be, I have a sf300 - 48P I can exchange this sg300 ENJOI trials.

  Thank you for anything you might suggest.

  Here are the details:

  -' Phone' is a phone to IP Avaya 4610SW or 5610SW (class 2)

  -"Watchdog" is an environmental monitor IT Watchdogs Watchdog 100 (class 0)

  -"WAP" is a Cisco WAP4410N (class 3)

  All initially due to lack of combination:

  GI10 phone #1

  gi22 phone #2

  dog guard gi23

  WAP gi24

  would result in the POE power to place on all ports, every 5 to 30 minutes.

  I disabled Green Ethernet completely - no change.

  And then made the following tests:

  1. "power never inline" on gi23 and gi24: problem disappeared

  2. 'inline power auto"on gi23 and gi24: problem is back

  3 ' power inline never' on gi23 only: problem disappeared

  4 ' auto of inline power' on gi23: problem is back

  5 ' power inline never' on gi24 only: problem disappeared

  6. "power inline auto" on gi24: problem is back.

  I left gi23 powered throughout the night and it was stable: it's about 10 hours without any problem.

  This morning, tried the following configs:

  08:54 - worked fine

  IG4 watchdog

  GI10 phone #1

  gi22 phone #2

  WAP gi24

  10:31 - added another phone, the problem came back

  IG4 watchdog

  GI10 phone #1

  gi22 phone #2

  gi23 phone #3

  WAP gi24

  10:43 - inappropriate phone #3 to IG11 (next) - problem continues

  IG4 watchdog

  GI10 phone #1

  IG11 phone #3

  gi22 phone #2

  WAP gi24

  11:00 - moved phone #3 to gi8 - suite problem

  IG4 watchdog

  gi8 phone #3

  GI10 phone #1

  gi22 phone #2

  WAP gi24

  11:31 - moved phone #3 article IG 14 - the problem disappeared

  IG4 watchdog

  GI10 phone #1

  Article IG 14 phone #3

  gi22 phone #2

  WAP gi24

  and that's where we left things now are stable for about four hours.

  The following products are the config more later (11:31).

  Hi Rich, reference this photo I just drew is a rough interpretation of how a switch 24 ports has guts. Each + block represents a processor. The numbers below represent the port Bank that corresponds to the transformer. Of course, MODULE POE is clearly identified. Each module 12 POE ports for services.

  I think you have a completely different question. If the POE works for 5 to 30 minutes, it can be a problem of layer 1 (bad son) or a different, perhaps material condition being disturbed. If the switch is at fault, it seems more likely to be defective to a unit of buggy.  I did a lot of research on the operation of the switch ASIC, transformer and modules of POE in the cohesion.

  Quite frankly, I think you should go to the 1.2.7.76 firmware, factory reset the device and test all the ports you want using the same equipment. If maintaining the POE fall every 5 to 30 minutes and you are absolutely positive, that it is not a question of layer 1 or a configuration problem on your products, can I just replace the switch.

• Fault on my Macbook Pro in Nigeria

  I have a macbook pro that I bought 2 years back and all of a sudden the laptop won't boot any more although when the load is connected the charger shows green color.

  I work in nigeria and made visit to the store in Mall i city of ikeja told that I have to send the phone to the service center located in the State of dolphin, ikoyi.

  I sent the laptop to the service center but was asked to pay a fee of about $ 50 (20 000 naira) American so that they can diagnose the failure on the laptop and then let me know what the fault is and how much it would cost to fix it.

  What is the normal procedure?

  Waiting for your answer? Anyone have a similar problem before?

  Kind regards

• PoE to power a switch

  Does anyone know of an Ethernet hub or switch that can be powered from Power Over Ethernet?  I have a location without electricity but with an Ethernet jack.  This would allow me to extend the network there without having to invest in the walls of the electrician and opening etc.

  Thank you.

  There are switches that can provide Poe or be powered by PoE equipment (such as Netgear and TP-Link) network suppliers. It is also possible to use a separate PoE injector for the provision. For switches/routers without possibility to be powered directly by PoE, a PoE splitter can offer an alternative solution. There are some limits of voltage and current (and temperature) that must be respected. In addition, always check the construction and electrical instructions for your country.

• My 5 years old Satellite Pro P300-19 q has developed all of a sudden a fault

  Without realizing, I posted the message below on the Forum we Toshiba:

  Hello

  My laptop which is 5 years old and has worked without any problems, has suddenly developed a fault I don't seem to be able to untangle. It starts ok and gets on the screen "Toshiba Leading Technology" and it's not there. Should not or reaction to something. I tried to enter the power on Start menu and pressing the F12 key, it recognizes and says 'Please wait' but nothing happens. It applies to "Configure" button F2 and F8. There is absolutely no response and HDD led light does not illuminate.

  I have not installed or changed anything. It runs Windows 7 and I don't have the recovery disc and the installation CD original W7 but they are useless if I can't access the startup option.

  I also removed the HD and connected by USB connection to my work desk and access all my files and programs, so it doesn't seem to be something wrong with the disc either.

  Can someone offer me some suggestions?

  ___I HAVE HAD THE FOLLOWING RESPONSE_; __

  Looks like you have a corrupted BIOS.

  I recommend asking Toshiba http://pc-support.toshiba-europe.com/ for any help. They got the disc special crisis to retrieve the faulty ROM BIOS module and instructions on how to install it.

  I contacted the technical service of Toshiba UK enclosing the message above but have not heard
  anyone after. Does anyone have information about this recovery disk and where I could get it?

  I also think that the BIOS can be troublemaker in the whole of the situation. When you start your machine, it begins with the verification of low level material and later start to load the operating system preinstalled.
  In your case the laptop is blocked for some reason any on this first step.

  Unfortunately, your options are pretty limited. What you can try is to remove the check and RAM modules and so portable HARD drive will pass this first stage.
  AFAIK the disk of this crisis is for internal use only so I don't know if you will get it somewhere. What you can try is to google a bit and maybe upload it somewhere with specific instructions on its use.

  In the end, I must say that these issues don't occur so often and I have to ask anyway: you may have updated the BIOS or done something that may be responsible for this?

• After upgrade to El Capitan, Python segmentation fault 11 after two commands are entered.

  2011 Macbook pro with Snow Leopard (8 MB RAM).  I upgraded to 10.11.4 and now interactive Python (2.7.2) is broken.   After you enter the two commands any (?), it crashes:

  I saw the posts here and on StackOverflow, saying that this problem is corrected in python 2.7.6 but I have a few questions:

  one) because it is a problem for a few years, why not upgrade the El Capitan installs a new version of python (if I understand correctly, the El Capitan installation includes)?   :/   For example, instead of everyone made the upgrade (at least in some versions) with the problem individually?

  Given that I apparently must upgrade to python:

  (b) I saw mention of problems with the evolution of the system version of python.   Can I change the version of the system (my preference), for example. 2.7.11, or do I need to install a version for my personal use?

  (c) how DO I upgrad.e the version of the system, or install another version?

  Thank you

  It is not the system Python, which is the version 2.7.10. What you get from "which python"?

• Strike number CP 2025 printer cleaning/fault

  Hello

  My company has invested in an HP CP2025 printer a couple of weeks, that is used on the network of eight or nine people.

  However, there is a problem where, after printing several pages, generally 3 pages, the printer goes into cleaning for a while and then comes up with a fault typing error. At this stage you hav press OK on the printer to continue the process. And then it repeats.

  The printer decides to print some pages twice, but not all of them also and it seems to be no pattern in which one she repeats.

  Any help will be appreciated, because I can't work this.

  Thanks in advance.

  Hi all

  We just got a new CP2025 gave us last night at our Church.  I am the tech administrator for the Church, so it was my task to install the printer with connection of the printer drivers.

  When we (me and pastor) installed the drivers from the printer and print a test page, we had those little dots on one side of the paper.  Thinking that it is just a toner sedentary, I took each individual toner cartridge, he trembled and succeeded him.   Always had the points.

  So, we looked at the documentation supplied with the printer.  Nada on what to do.  Says "For the resolution of problems, call HP Support."  Then I give the floor.  the hours are from 8 to 8 East, so they are closed.

  My pastor calls for HP support today - the tech told him that "cartridges of toner in a printer that has remained in the warehouse will be deposited."  You must clean and calibrate the printer to remove it. ' So he did, and the points disappear.

  This is - why isn't that one of the installation steps in the paper documentation that came with the printer?  We have cleaned the printer last night, and calibrating it, it is not very clear on how to do it.

• Fault resilient boot!

  I came across a fault resilient booting. What is c?

  You must have two or more processors installed on your machine if you have encountered a FRB. If the boot strap processor (BSP) fails to complete the boot process, FRB intervenes and try to boot the system using the replacement processor. If the replacement processor is functional, the system starts.

• Satellite C850-1NU - BSOD with Page fault in non paged area error

  So basically I was looking through the web on my laptop, and then suddenly I got a blue screen of death.
  It said Page fault in nonpaged area.

  Some people say it means that the RAM could be faulty.
  Is this true and if it is faulty should I take it back to PC world where I bought it?

  Thanks ;)

  Hello

  The BSOD could be caused by system problems or malfunction of the equipment.

  .. and Yes; the BSOD containing the paginated Page Fault in any area error could be related to memory problems, but it could also be a temporal problem that appeared one last time

  But if this BSOD will appear in the future for the umpteenth time, I recommend you contact the service partner to verify the material.

• I get my internet through a Repeater.  There is a POE carrier then online, then a router adapter yet.   Can I use an Airport Extreme with POE to improve my WiFi range?

  I live in Baja California Surinamese no cable.  You want to improve WiFi.  Not sure how to interact with a POE.  Tried to set up the airport without a bit of luck.  Appreciate some feedback.

  If the connection between the POE (Power over Ethernet) device and the AirPort Extreme is a wireless, then you will not be able to extend the network Wi - Fi of the OCB in the extreme. This is possible with an another AirPort base station.

  In addition, only a particular model of the base station AirPort Extreme POE supported wired connections. It was discontinued in 2007 and is model # A1034.

• Satellite M40X-230: display fault - vertical lines

  My laptop crashed last night and on itself reboot screen displayed (spaced on each 8mm) vertical dotted lines and then crashes with the following message (edited for the relevant points)

  "Windows was arrested to avoid any damage to your computer.
  The problem seems to be caused by the following file: ati2dvag...
  The device driver got stuck in an infinite loop. This usually indicates problem with the device itself or with the device driver...
  "Technical information: * STOP: 0x000000EA (0x822185B0, 0xF8972CB4, 0 x 82133288, 0x00000001)".

  The screen is damaged now wherever the phone is turned on.

  However, if I have it start again, after the error, then mode message without failure, once Windows is used the display looks good (he is still defective prior to this, however). The same fault also occurs with an external monitor.

  I tried to uninstall the driver for the graphics card, but that makes no difference.

  Any ideas? I would like to reinstall windows, but that the fault if poster before the aircraft reach POST I really don't think that will make all the difference. That the screen is in Mode safe but not while it is booting up also does very much make sense to me either.

  Thank you very much to get this far in my ramblings.

  Rich

  Hello

  According to the error message:
  "... This usually indicates problem with the device itself or with the device driver... »

  It may be a faulty graphics card because the same defect appears on the external display. But diagnostic tests are required to be 100% sure what s the fault could be.
  The Toshiba service partner can start the test and then can give you some details about the failure. So, in my opinion, you should contact Toshiba service partner in your country.
