Catalyst 3550, SecureCRT > COM3 connected > Blank Screen

Day 1

Hello

I am very new to the CISCO world! Preparing for CCNA and thought having a laboratory at home would be a good idea! Got stuck on the first session never :(

I got Catalyst 3550 which is connected via a USB-Serial cable, after 2 days has got to get it connected to the COMM port. However when I run my switch with SecureCRT open, it does nothing. Just a white screen.

Could not find good help online, may be new to the world of networks and research my problem with wrong keywords. Finally I thought to go to the CISCO forum looking for an answer to my problem...

Everyone, please help!

Much appreciated! :)

Day 2

After a few hours of waiting and trying a few other things, thought to try if the COMM ports are working OK or not.

Using Windows command prompt.

Echo Hello > COM1 (directed by management of devices in use) return no error message doesn't mean works great!

Echo Hello > COM3 (as directed by management of devices in use by my USB serial adapter) return no error message doesn't mean works great!

However when trying to glazier, SecureCRt and Tera Term my Catalyst 3550 does not load anything on the screen and just a blank screen with blinking cursor.

Someone please help!

Hello

other options:

-use another COM port

-updated driver for USB-to-serial adapter

-use another USB-to-serial adapter

-use another outside the secure crt terminal emulator software: PuTTY teraterm, hyerpterminal,.

-Try another PC/laptop (the oldest is serial port)

-Try a USB-to-serial cable and console on another router/switch

If all else fails, I propose to replace the 3550.

    Hi AndyCantore,

    Follow these steps:

    Step 1: Start the computer in safe mode and check if the problem persists.

    Start your computer in safe mode

    http://Windows.Microsoft.com/en-us/Windows-Vista/start-your-computer-in-safe-mode

    Step 2: If the problem does not persist in safe mode, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

    Note: After completing the steps in the clean boot troubleshooting, follow the link step 7 to return the computer to a Normal startupmode.

  • I get a blank screen just before the connection with a single visible cursor

    Currently, my computer will load where the login screen should appear, but instead merely display a white screen with the mouse cursor in the middle that I can move around.

    I tried restoring the system manually at a point in time that he began to arrive. That did not work. I tried a restore of the system manually to a time past, does not work well before it began. I tried to have my computer to do in the repair option to "restore to the last known good configuration" and that did not work. I ran various programs that look for malware, spyware and viruses many times and found a few things, but nothing of this has solved the problem. I tried to check all my drivers and they say all work and all drivers say they do not need an update. I tried the system repair tool and he found nothing wrong, even with the memory to check tool that finds nothing wrong. If I press SHIFT 5 times to the white screen with the cursor, I'll hear the keys to self-retaining beep, but no prompt.

    One thing that happened was that I was once in the blank screen and I pushed to escape and I noticed that the cursor has turned to an hourglass. Then I tried Ctrl alt delete and which opens a command prompt and from this command prompt it allowed me to go to the usual login screen. Then, my computer work as it did just before this problem (a warning would pop-up Windows saying that it stopped a program that you try to start itself without permission and who would be come like every minute or so). But since then I havnt been able to reproduce this same result to load or by opening the command prompt.

    And safe mode works very well.

    I was reading around online and there was something that said they had the same problem and download internet explorerer 7 helped. as well as a similar problem which was fixed when IE8 was downloaded an update of windows. the guy deleted and it was fine since.

    I tried to download the latest version of Internet Explorer, but it cannot be loaded without rebooting, and I can't enter the normal screen that opens after the cut to finalize it. I always still try to remove it as well as the update of windows.

    Another difference I noticed is in the loading bar than before windows starts as the login screen. It used to be thick green blocks that crossed with the windows logo. Now, it's a block really thin yellowish green (which reminds me of the life blocks Mega Man in his health bar if that helps lol) and no windows logo because it does it (if it says copywrite along the bottom windows corporation).

    If anyone has more aid in addition to the info windows give a repair tool, please help. Thank you.

    ===============================================================

    Here's what I use and recommend: (these are all free and very effective versions.)

    Avast and Prevx proved extremely reliable and compatible with all I have
    launched on them. Microsoft Security Essentials and Prevx have also proven to be very
    reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

    Avast Home free - stop any shields is not necessary except leave the file system, Web,.
    Operational network (Script and behavior are also recommended in Ver 6 +).

    Prevx - Home - free

    Windows Firewall

    Windows Defender (is not necessary if you use MSE)

    Protected IE - mode

    IE 8 - SmartScreen filter WE (IE 7 phishing filter)

    I also IE always start with asset if filter InPrivate IE 8.
    (It may temporarily turn off with the little icon to the left of the + bottom
    right of IE)

    Two versions of Avast are available 6.x and 4.8 x

    Avast - home - free - 6.x stop shields you do not use (except files, Web, network, &)
    Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
    Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
    Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
    disabled - click OK
    http://www.avast.com/free-antivirus-download

    Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
    and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
    Finish those you don't use).
    http://www.avast.com/free-antivirus-download#TAB4

    Or use Microsoft Security Essentials - free
    http://www.Microsoft.com/Security_Essentials/

    Prevx works well alongside MSE or Avast

    Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
    programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
    or use Google to see how to remove.
    http://www.prevx.com/   <-->
    http://info.prevx.com/downloadcsi.asp  <-->

    Choice of PCmag editor - Prevx-
    http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

    Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
    would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
    (not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
    never find anything of note that I started to use this configuration.

  • G1V01UA-ABA: Blank Screen of Death, Please Help.

    I've had this computer for about four years. He never gave me any problems.  Year last completely off and would not turn on. I scoured every forum, every miracle solution, but nothing. I constantly run across a single problem at all, none of them are exactly my problem.

    White screen, Check.

    Flashing Orange button Wifi, check.

    Flashing caps lock, incomplete.

    I see the time and time again there must be a flashing caps button, but it flashes never for me, only the wifi button. It also flashes symbol of white power on the side of my computer, but that's all. The battery is fine, I need to hard reset it, believe me, I've done about 30 times, I don't have to mash the F2 or F11 buttons, it does not connect to an external monitor, nothing. Please, I beg you. I really need to solve this problem. I went through around $1,000 dollars on replacement computers and it's the only one that I really relay. If you can think of a good way for me to solve this problem which has already been mentioned, it would be apperciated.

    Also, note aside, do NOT refer to support me, because I spent more than 15 hours trying to contact support and never help me with everything that I need. HP has horribile customer service, but that's normal.

    Using the F8 method:

    1. Restart your computer.
    2. When the computer starts, you will see your computer hardware are listed. When you see this information begins to tap theF8 key repeatedly until you are presented with theBoot Options Advanced Windows Vista.
    3. Select the Safe Mode option with the arrow keys.
    4. Then press enter on your keyboard to start mode without failure of Vista.

  • Unrecoverable blank screen after Windows 10 update - Inspiron N50500

    Inspiron N5050, launched in January 2013.

    Updated recently for Windows 10 without incident. The laptop worked well for several weeks. It is only after the updates started coming my problems began.

    After each of the first two updates and customary restarts, the screen would go blank. There he remained for two or three days until that for some unknown reason, the office became visible again. Basically, all I did was start it, leave it on for a few hours and restart again. I repeated this process over and over again for a few days. I also consulted a number of forums online Meanwhile, tried some of the suggestions offered without result. Basically, everything seemed to go down to this boot, wait, re - start process again. This makes little sense to me, but something caused the screen become operational. .. There are nearly ten days until this last update.

    As you can imagine, when Windows told me that the next update would be applied at the next restart, I saw it with concern and discontent. And this time it didn't come back.

    With the exception of the white screen, the computer seems completely functional. The screen is not completely black, but appears to be backlit. There is a noticeable glow emanating from it. I am able to enter my password at the right time and he will finish the boot process.  I can't see anything on the screen.

    Today, I inserted the recovery disc I made when I turned on the computer the first time only whether end with the following runtime error:

    "Program: X:\windows\system32\RESTORE7.exe.
    This application has requested the execution to terminate in an unusual way. For more information, contact the application support team"

    Restore7.exe Application error
    The exception unknown software exception (0 x 40000015) occurred in the application at location 0x4011398e
    Click OK to terminate the program

    Usually, I try to do all the right things, but it is doubtful that Microsoft or Dell will have any interest in solving my little dinky problem. So, I hope some of you can offer some suggestions. I'm pretty dead on the water and ideas.

    douglasgrubbs, I hope you can see, because it seems that I might have found a solution.

    I found an old monitor in the confines of my attic, hooked up to the laptop and booted up. Alto! I had a visible desktop. After a time, a message popped up indicating the need for a reboot. Not a cold, hard starting. A REBOOT! There are 10 Windows updates that should be installed, and they could only be installed on a restart. (This is the part I'm missing because I couldn't see it on a blank screen).

    I clicked on "Restart now" on the message and let it go. (It took a bit of time to install updates)

    Douglas, if you see, find and connect an external monitor and all updates waiting for you. This has been the problem all along.

Maybe you are looking for
