• Satellite A100-033 - where to get the cable/connector for power switch?

  Hello

  I change the cable/connector for * power switch button * which connect to motherborad. If anyone no where I can get in? I tried at PC world, but they do not have cable, I am looking.

  My laptop SPAC:

  Satellite A100-033 part number: PSAANE-03J02GEN

  Thank you

  Hi rjbuz,

  I can t tell you the part number because I m not the owner of the Satellite A100, but a service provider authorized in your country can do this:
  http://EU.computers.Toshiba-Europe.com > support & downloads > find an authorized service provider

  Just give them a call and ask. Maybe they can send you the replacement part. :)

• X 240 - in any case automatically confirguring Ethernet/WLAN switch when / logout...

  Is he still automatically confirguring Ethernet/WLAN switch when / logoff other than the use of ThinkVantage Access Connections?

  Logins is pretty infallible to deliver to users and there seems to be a way to massively.

  Anyone done any other way? HP has a setting in BIOS and Dell has a utility, but all of the Lenovo has seems to be source access.

  Hello

  Lenovo's AC under win7 is an excellent application, fine, you need including.

  However, there are many other methods, tools based OS on only.

  In addition, if the wifi adapter is produced by Intel, you can use PROSet features. Read the next page:

• Switch ports connected with cross cable on the same switch...

  Hi experts,

  Just got a doubt.

  If both a stand-alone switch ports are connected by a crossover cable, how will be the stp of attitude toward this scenario...

  Thank you

  Arun

  Hi arun,

  As we all know the switches use according to criteria of application PLEASE:

  (1) to root the lowest BID

  (2) a low-cost path to the bridge root

  (3) OFFERED the lowest sender

  (4) minimum port priority

  (5) the lowest port id.

  So in your senario until number 4 allvalues will be equal and there will be a match tie. So for port breakage id will be used and the port with the higher port number will be blocked and low port id will be in a State of fwding.

  Example:

  If you've been through e1/1 and e1/2 cable on the same switch then 1/1 b in condition of fwding all-in-1/2 will b in the blocking state.

  HTH,

  Kind regards

  Shri :)

• For Fast Ethernet SFP modules

  Hello

  We are looking for fiber-to-ethernet converter.

  Is there any SFP module that plugs directly into the Fast Ethernet to a switch port.

  Please visit the following link: -.

  http://www.Cisco.com/en/us/prod/collateral/modules/ps5455/ps6578/product_data_sheet0900aecd801f931c.html

  He said "the Cisco100BASE-X Form Factor Pluggable SFP (Small) (Figure 1) is a hot output device that plugs into the Fast Ethernet ports, dual rate Fast/Gigabit Ethernet ports or Gigabit Ethernet from a Cisco switch ports or a router, which connects the port with the fiber cabling network.".

  If this module can be plugged into any port of FE, is it compatible with Cisco switches only?...

  Please reply,

  Thank you

  Amit

  The SFP port is just a place where the optical SFP is sitting in the switch (connect internally to power, data bus, etc.). SFP offers you the possibility to install a plug-in to adapt to the requirement of the network; If short-range fiber, fiber long reach or same RJ45 without changing an entire line card or switch.  SFP ports are integrated in the switch by a manufacturer, not bolted on after.  The specification for the connector module and SFP interface is detailed in an SFP MSA (multi-source agreement); designed to offer a platform in the industry to build.

  If your switch has a fixed electric port and you do not have access to power (for a converter to media or other), then the terminal switch will be replaced by a device with a fiber interface option. That, or you'll find a power on fiber system with enough power to drive a Media Converter (which I don't think that there are still).

  I hope this helps!

• How is it that a computer which works very well with a direct Ethernet connection won't work with a switch, however any other computer using the same port, cable, ect, and so on, can?

  Switch issues. Help, please.

  How is it that a computer which works very well with a direct Ethernet connection won't work with a switch, however any other computer using the same port, cable, ect, and so on, can? We already checked the firewall as a question, that it was not, and now, we are puzzled.

  Well, I know that the issue is long-term... believe me, it's a long, but as they say, the devil is in the details. Anywho, the question is, my grandfather has a HP laptop, which for two years has been able to run through a Linksys switch to his router and connect its printers to his laptop. About two months ago it suddenly doesn't work like that. Now, it works fine if it plugs directly into the router/Ethernet. My uncle suggested that the switch was bad, but after testing the same port, cable and all, the switch worked well for him. ' GRAMPS really needs this answered, but someone else, it is called can not understand and now I, in turn, ask you all for what you can offer. Here are the ideas that we have already discredited.

  -Switch bad: as above, is that this particular laptop, even under identical conditions, the works of my uncle very well.
  -Bad NIC: debunked through the fact we connected to the computer directly to the router and it worked fine.
  -Bad configuration of the firewall: we have disabled the firewall (please do not notice, he wasn't the smartest idea, we already know) and even if she recorded the switch exists, the internet is always triggered when you are connected with the switch.

  Thanks in advance for any assistance that you can provide and Merry Christmas to you all.

  It would be useful to consult the results of the ipconfig/all command both when it is connected to the switch and when it is connected directly to the router.  In addition, what is the model of the switch?

  To save the manual copy and the new hits of the ipconfig/all command output-

  First connect through switch.
  Open a command prompt window (start > run > cmd > OK)
  Type the following lines in the black command prompt window and press ENTER after each line

  echo "Connected via the button" > "% UserProfile%\Desktop\ipinfo.txt".
  ipconfig/all > "% UserProfile%\Desktop\ipinfo.txt".

  Now connect directly to the router, type the following lines in the command prompt window and press ENTER after each line

  echo "Connected to the router" > "% UserProfile%\Desktop\ipinfo.txt".
  ipconfig/all > "% UserProfile%\Desktop\ipinfo.txt".
  Notepad '% UserProfile%\Desktop\ipinfo.txt '.
  output

  Copy the contents of the Notepad window in your response (if you use the laptop when it is connected directly to the router) or close the Notepad window, and then copy ipinfo.txt of the laptop to the Gramps in a USB FlashDrive you can connect to any computer allows you to answer.

  You can delete ipinfo.txt on the desktop when you are finished.

• T460 touchpad responds liked when the Ethernet cable is plugged

  Hello

  I bought a brand new ThinkPad T460 ten days ago and I noticed that when I plug in an Ethernet cable, the touchpad responds: just a few clicks and taps are missed, the movement is slow and and sometimes temporarily blocked. The touchpad comes alive again as soon as the Ethernet cable is disconnected. The trackpoint and trackpoint button above the touchpad are not affected, only the touchpad starts to misbehave.

  This happens on both Windows and Linux, this isn't a problem of specific operating system. Furthermore, I checked to see if I am running the latest version of the BIOS, and I am. And there are no problems when you use the wireless adapter, but one of the reasons why I bought a ThinkPad was she has a port Ethernet, so not being able to use it would be extremely disappointing.

  I checked to see if there are any IRQ conflicts for the touchpad, but could find none. The problem occurs when the computer is plugged in and when it runs on battery only. I also tried two different cables in the same router, each in a different router port, and the problem persisted.

  I'm using the latest drivers for Windows 7 directly on the Lenovo site, and Arch Linux with kernel 4.4.5 - the Ethernet card is considered:

  e1000e [2.751703]: Intel® PRO/1000 3.2.6 - k network driver
  e1000e [2.751705]: Copyright (c) Intel Corporation 1999-2015.

  Should I expect it is fixed with a BIOS update, or do I have to contact guarantee? It is unacceptable to live with it.

  Tried in another House as promised, and the touchpad works very well with cable Ethernet is plugged. Also, before you leave the House with the problem, I discovered that the problem occurs only when the cable from my ISP switch is plugged into my router.

  Respect my opinion that this machine deserves a stronger touchpad, but apparently is not due to lack of computer - under normal circumstances, there is no problem with the touchpad.

  I'm stumped on how to proceed. Can I use a multimeter on the ISP switch from cable, but I'm not sure what to check (voltage? how does and between what son?). I'll also look into the suggestion of ferrite, I don't know where they are available - this thread is first heard of them.

  Anyway, I wanted to just erase Lenovo name on it.

• Satellite Pro U300: Error Message: cable is disconnected, but Lan cable is connected

  Hello

  I have problem with interface ethernet (wired) in my Satellite Pro U300. I use in many places (home, office, customers) and when I restore in sleep or hibernation mode interface ethernet shows that the * cable is disconnected *, despite the connection of the cable * is * connected and works perfectly with all other devices, laptops and PC.

  The switch also shows that the there no signal link. But re - activate the malfunctioning ethernet port, just disable the ethernet interface and then after 5s (1 s is too short!) turn on.

  Then a baloon in taskbar window indicates that there are 10 Mbit/s link, but actually, the link works at 100 Mbps (I can see it in the connection status window and the ethernet LEDs switch). This is the only laptop that has this kind of problems.

  I have the latest version of the installed ethernet 5.664.205.2007 driver on Win XP SP2.

  Is it possible I'm getting rid of turn on interface ethernet several times per day (except change laptop)?

  Hello

  I put t have a real solution but I have a few proposals of solution

  First of all, you should check in Device Manager if the network card has been properly recognized. The Ethernet card should be listed under network without any yellow exclamation point cards.

  If the network adapter has been properly recognized, then the next step should be checking the properties of the LAN connection.
  There, you should check the properties of the TCP/IP protocol.
  The settings such as IP address automatically get & address of DNS server automatically get must be marked.

• Unable to connect to the network after having extended to a second Airport via ethernet router

  Hello

  I have a 5th gen airport extreme that did a wonderful job providing the wifi to the majority of our House. Unfortunately, in our room on the floor, we have a (good) connection causing a constant depreciation with netflix that my wife was not fond of.

  Today, I ran a line of 100 feet of ethernet in my attic and connected my previous dual band gen 3 airport extreme. I have reset the router and configured from scratch. When it has completed the Installation Wizard to "expand my current network." as soon as the router is online, our network goes off. I can unplug the second router and starts all over again. but when it is connected. my devices ask for network password and fail to connect.

  how our network is set up:

  Modem - Airport Extreme (5thgen) - ethernet 8port switch - Airport Extreme (3rdgen)

  All are wired using the cat6 cable.

  Any help would be greatly appreciated.

  Please perform a hard reset on the 3rd Gen AirPort Extreme as follows:

  Turn on the airport for a few minutes

  Pressed the reset button on the back of the AirPort Extreme for 5 to 6 seconds

  Release the reset button and allow a minute for the airport restart to a slow, flashing amber light status

  

  Temporarily, move the 3rd Gen airport close to the airport of Gen 5 th and connect short, spare Ethernet cable... no matter what length will make... among the <-->LAN ports on the 5 th Gen to the "O" WAN port on the 3rd Gen airport

  Turn on the 3rd Gen airport for a minute or two

  Rerun the installer... who will suggest that the 3rd generation will extend the signal of the 5th generation, enter a name for the 3rd generation device and click Next. Your screen will be similar to the example below, but will show your devices and the network name.

  

  Monitor the following very closely to ensure that the 3rd generation is currently set to spread with Ethernet.  This indicates that the installation wizard recovers the Ethernet connection, so the 3rd generation will be configured correctly.

  

  Wait another minute until the 3rd generation is configured and working properly... and check that it causes NO problems on the network as if it was before, when it was not properly configured.

  Now move back the 3rd generation to the remote location and connect the Ethernet cable to the WAN port on the 3rd generation.  If your cables Ethernet works correctly, the 3rd generation will work properly.

  If the 3rd generation does not work properly, then you will need troubleshoot the Ethernet connection and, eventually, the Ethernet switch... Since you know that the 3rd generation has been put in place properly and it works well with the other short Ethernet cable.

• Trouble connecting Netgear XS748T to Ubiquiti UniFi US-48-750W via Port SFP +.

  We bought a new switch Netgear XS748T and try connecting to our existing network which consists of several switches of Ubiquiti UniFi US-48-750W, and we try to connect using the SFP + 10 GB ports on the two switches. We have a Direct Link SFP + SFP + DAC, passive, 1 m, cable AWG30, we bought at Amazon / 10Gtek and when we try to use this cable between the Ubiquiti switch and the Netgear we get no link activity.

  However if we use the same cable between two of Ubiquiti switches it lights immediately and works very well, the same is true if we use the same SFP + cable between the switch Netgear XS748T and a XS728T that we must also. Its almost as if the switches detect the same manufacturer at the other end and right link up but when its manufacturer another pass on the other end, it does nothing.

  It is very aggravating, and Im going to be obliged to return the new Netgear switches. Can someone make a suggestion or confirm if they should or may not work? Everything simply connecting switches together using a cable of copper works very well but since our current switches don't support 1 GB via copper it provides not enough bandwidth for our use so we really need the port SFP + 10 GB to give us the uplink.

  Here is a link to the modules SFP + cable, we bought:

  https://www.Amazon.com/DP/B01LSGGUOY/ref=twister_B01M0ER4M0?_encoding=UTF8&PSC=1

  It seems that I solved the problem myself. I bought a set of:
  10Gtek for Cisco SFP - 10 G - LR, 10 Gb/s Transceiver SFP + module 1310nm 10km

  And the LR version worked instantly. I honestly don't know what's the difference between a SFP + SR module and a module LR SFP +, but for some reason any LR module has allowed these two switches to connect.

  Here are links to the modules and the cable used in case anyone needs a solution to this:

• 7000 R as point of access one using the integrated switch

  I use the first 7000 R as a router and the second 7000 R as an Access Point. I can even if need the integrated switch of one Access Point is this switch automatically connect with the same netzwork?

  Marcel

  You can use all of the ports on the R7000 in AP mode. They are in the same network. If your access point is configured properly on the ports of the AP devices, should receive a valid IP address / gateway to the Base R7000 (DHCP server). You could even hang it cut one of thos ports, if you wanted to... Make sure that you are running at least cable CAT5e Ethernet between the R7000 AP and the Station of Base R7000 to connect the two devices.
