SF 200-24P does not see the MGBSX1

I have a SF 200-24P and plugged in a MGBSX1.  I am logged into the web interface and see that nowhere does the switch acknoledge the mini-GBIC.  I can see that the GBIC is powered on.  If I plug the fiber in, the transceiver on the other end shows a link.  In fact, the transceiver's loop-back test reports all is well.  The switch however will not pass network traffic!  I tried both mini-GBIC ports.  I tried another brand new mini-GBIC from SMC, still no joy.  While I do not have another SF 200-24P to try out, I do have a SG 102-24 and plugged the MGBSX1 into it.  I'm still not transmitting data, although I do not know of a way to test it other than to plug it in and see if data transmits.
Is there something 'extra' I'm supposed to do in the web interface to get the swtich to 'see' the mini-GBIC?  I'm to the point of returning the entire setup and just use a standalone transceiver on both ends.  Help?

Hi Jerry,
The Sx200/300 series only show the SFP module in the diagnostics when there is an active link, otherwise it does not show any data. When the link is connected you should see them there. Verify the settings in the SF 200-24P under Administration - Diagnostics - Optical Module Status.
As far as the "not passing any traffic" problem is concerned. Are the ports that you are connecting in the same VLAN ? If they are not, that could be a reason why there's no traffic passing. Also verify STP settings, you might have a port blocked by STP if you have redundant links (I guess that is not the case but I can't see from here of course )
Hope this helps,
Best regards,

    I have a new time capsule (replace my old time capsule).  I want to erase my old one.  My computer does not see the old one anymore, how do I connect it (the old TC is not connected to modem).  I want to erase it and then use it as either a second hard drive (sired/sirelesly?) or as a hard drive/bridge.  So,
    1.  why doesn't my cmputer see the old TC
    2  once i have solved that, how do I erase the old one
    3.  Can I use the old one as a supplemental hard drive
         a.  wired?
         b. wirelessly?
    4.  Can I use the old one as a range extender?
    I know .. a lot of questions but I would appreciate any help.

    1. Because it is either the same IP as the new one or hidden by being plugged in as a second router.
    To access it, isolate one computer from the existing network and plug it directly by ethernet to a lan port of the TC. Use the erase function in the TC to remove all the content of the hard disk.
    Then go to the internet tab, connection sharing and select off bridged. You can then reconnect the TC to the network.. and the computer as well. The TC will act as bridged device.. getting IP from the main router and should then appear correctly in Airport utility.
    2. I covered in 1. But you just go in airport utility manual setup. disk, and you will see the erase function. You can also set it to bridge and leave the erase until you put it back in the network.. but be careful you erase the right one.
    3. You can use the old TC via wired or wireless.. although I would always stick to wired connection if possible. Speed on wireless is 10x worse than wired.
    Also note the reliability goes down dramatically after 2 years.. a series 1 3 years old or more is ebay fodder unless you want to repair it. Do not trust vital data to it.. when it dies you will have issues recovering it.
    4. Yes, all apple routers will function as wireless extenders. when you do that the ethernet ports turn off so it becomes a purely wireless device.. strange apple decision on what you want to use your TC for.

  • Wiped our old iPad 1 clean, now can't install iOS from iTunes.  iTunes does not "see" the devise.  Tried uninstalling and installing iTunes on laptop.  Also bought new USB cable.  The iPad is charging, but that's all it does.

    Wiped our old iPad 1 clean, now can't install iOS from iTunes using laptop PC (W Vista).  iTunes does not "see" the device.  Tried uninstalling and installing iTunes on laptop.  Also bought new USB cable.  The iPad is charging, but that's all it does.  Just want to get it operating again for browsing and e-reading.

    OK.  You merely erased the content and settings.  The IOS is still there.
    If it has NEVER been jailbroke, here are some standard repair procedures.  From what you've already stated, my guess is that you'll end up with Recovery Mode described in the last paragraph.
    First, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow the on-screen directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore (or it doesn't help), go into Recovery Mode per the instructions here.  You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again.  Also, read this.

  • My iMac does not see the new Toshiba external drive in Finder or Disk Utility.  How can I get it to see the drive?

    My iMac does not see the new Toshiba external drive in Finder or Disk Utility.  How can I get it to see the drive?

    From the menu bar, select
               ▹ System Preferences ▹ Energy Saver ▹ Power Adapter  
    and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
    If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
    Check that the data cable is securely inserted at both ends.
    Try a different cable.
    If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
    If you're connecting it directly, try a different port.
    Disconnect all other devices on the bus, or as many as possible.
    Test the drive with another Mac. Test another drive with this Mac.
    If the drive is bus-powered, but has an AC adapter, connect the adapter.
    Start up in Recovery mode and launch Disk Utility. Is the drive recognized?
    Start up in Safe Mode and test.
    Reset the NVRAM.
    Reset the System Management Controller.
    If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive is malfunctioning.

    Return it and get your money back. Virgin does not offer official unlocking, thus there's no way to get the phone officially unlocked for you to use it.
    Sorry, but you wasted your money.

  • I am trying to install a second airport express to extend my network. When I use the aiport utility it does not see the second airport express.

    I am trying to install a second airport express to extend my network. When I use the aiport utility it does not see the second airport express.

    Suggest that you perform a Factory Default Reset as follows:
    Pull the Express from power
    Wait a few moments
    Hold in the reset button and keep holding it an additonal 8-10 seconds while you plug the Express back in to power
    Release the reset button and allow 40-45 seconds for the Express to restart
    Apple's instructions to do what you want are here:
    It will often help to temporarily connect an Ethernet cable from your Mac to the AirPort Express for the setup. Once the Express is configured, you can disconnect the Ethernet cable and move the Express to the desired location.

    Although an AirPort Extreme is shown as the extending device in the example, the setup for an AirPort Express is exactly the same

  • I am trying to import i frame from an SD90 video camera to iMovie, but it does not see the camera. Footage goes to i photo Why?

    I am trying to import video ( i frame) from an sd90 ( listed for mac) but i movie does not see the camera. It imports into i photo. Is this normal ?

    If you quit iPhoto and iMovie (with the camera still attached) then put the camera into VCR playback mode. Then launch iMovie and see if it can see the camera. If not, get out the power adapter for the camera and plug it into the wall, plug the camera into the power adapter. Reboot your Mac and wait for iPhoto to launch again automatically. Don't let it import the clips, just say No, quit the program. Then put the camrea int VCR/Playback mode, launch iMovie and check again to see if it can see the camera. Once iMovie sees it the first time it should be quicker to recognize it in future. But iPhoto does try to race in there and grab everything first.
    To turn this off go to iPhoto Menu in iPhoto > Preferences > Look for Connecting camera opens: (click on the pulldown menu and choose No Application) This effectively turns off iPhoto when you first attach the camera. And it opens the way to iMovie recognizing it quicker.

  • I have a MacBook Pro running 10.7.2.  I am trying to import photos from my older Canon EOS-1D for the first time since my OS upgrade.  iPhoto does not see the camera nor does Image Capture.  IC says there is not a camera connected.  Cable is known good.

    If neither iPhoto not IC can seethe card it might suggest an issue with the card or the ports on the camera/mac.
    Try reformat the card, change the ports and/or use a USB Card Reader.

  • IPhoto does not see the camera

    iPhoto does not see the camera, although it worked really well for two years. Computer has been regularly updated. Please help, thank You.

    Image Capture doesn't see the camera. I have tried with two different Sony cameras, that I have been using for a long time on this computer. It is iMac 27''. Both of these cameras work normaly in MacBook Air, that means that the problem is not in the camera, or the cards. Those are the things I have tried so far. Only difference I created on the computer is that I have, two or three days ago, installed external hard drive WD My Book Studio which is connected to the computer by FireWire 800.
