New replacement of the 4250SX model

Our customer wants to order a replacement unit for the existing 4250-SX models that are installed.

On the web page of Cisco, they mention the sensor Cisco IPS 4255 (chassis, software, SSH, four 10/100/1000Base-T connector RJ-45-IPS-4255-K9)

If you need fix the 4255 IPS to a switch catalyst 6500 using a SX connection, is there a special card, which must be ordered or is the bundle model which can be ordered for this purpose.

Thanks in advance...

The IPS-4255 does not support SX interfaces at this time.

Understand that the IDS 4250 SX was not replaced by the IPS-4255.

It's only the ID-4250-TX standard which has been replaced by the IPS-4255.

The IDS-4250-SX IDS 4250 XL have not been replaced and are always available.

The IDS-4250-SX and IDS-4250-XL are still the IDS/IPS only platforms that are supported by the SX interfaces.

If a replacement is necessary the customer can either order a different ID-4250-SX (or even an IDS 4250 XL) or set up a copper TX interface on the switch and may then order the IPS-4255.

If the customer intends to order a replacement as just one part of a standard upgrade cycle and current IDS-4250-SX still works very well; I would recommend then they continue just by using their current unit.

The IDS 4250 SX is fully able to run the IPS v5.0 in promiscuous mode software.

If they want to run the IPS v5.0 in InLine mode, however, so I recommend buying just the XL card that contains 2 SX interfaces and can be used for InLine monitoring.

They allow to swap the new XL card with the existing SX card on their current unit without the need to buy a new sensor.

  • A small question about the replacement of the DVD in a HP Pavilion dv6 - 2057cl

    I need to replace the DVD drive in this dv6, and I wonder if there is room for manoeuvre with regard to the replacement drive.  Can I use another drive to disc HP with a similar model # or am I limited on drive 'identical '?

    Some quick info follows:

    OS = Windows 7 home premieum (32 bit)

    The disk removed from the laptop:

    DVD Super Multi writer

    HP mPC REF: 461646-6 c 2

    S/N:
    {Removed privacy}

    MANUFACTURED: OCTOBER 2008

    I found a replacement with the same 'model' and even 'HP mPC PN' but it was made in 2009, and I don't know whether or not the implementation of the SATA connection on the rear of the car fits.

    Any help is very appreciated!

    Thank you

    It seems that the reference is the same. As long as the part number is the same, it is essentially the same part and should work without any problems. The only time where this part can fail if the part number is different. If a part is different from another part (software, hardware, etc.), it will have a different reference number. Also long that 461646-6 c 2 is identical on both, there is no problem with the disk replacement.

  • How can I combine all pages of the site to a new page of the site?

    Hello

    I use Dreamweaver cs4 on a windows pc. I have 12 pages of my site with a spry vertical navigation bar. Whenever I create a new page I then add that to the spry navigation bar. All other pages do not show this new page in the navigation bar. Thus, the spry NAV. must be site wide update. Is it possible to update the spry navigation bar site wide in a few clicks? Is there an easy way of all the other page a link to this new page? I have a rendering template, but all pages on my site are now detached from this model. Whenever I saved the template in an html file to create a new page in the navigation bar was the word inside template, so I just deleted it out of the code. As you can probably I'm pretty new to dreamweaver so any help will be greatly appreciated to say the least. I checked everywhere wherever I can think of for the answer

    Thank you for taking the time to help, dluthier

    Is it possible to update the spry navigation bar site wide in a few clicks? Is there an easy way of all the other page a link to this new page?

    Yes, there are ways to have all the pages to be updated when you make changes to a navigation bar.  However, the way you describe the situation you currently do it all manually.

    The easiest way to update a navigation bar:

    1. the use of serverside includes: this is a basic tutorial explaining what is a SSI and how it's done.

    http://bignosebird.com/SSI.shtml

    2. the other is the use of models - that you tried.

    I have a rendering template, but all pages on my site are now detached from this model. Whenever I saved the template to a file html to create a new page in the navigation bar was the word inside template, so I just deleted it out of the code

    That's where you went wrong, you save the template with a new name, and save it as an html file.  You must use: Create New > model.  This way, you create a new page of the master model and save it in the root of your site - and this is what is called a "page of the child".

    Using DW templates:

    http://www.Adobe.com/devnet/Dreamweaver/templates.html

    The differences between the use of SSIs and DWTs (template file):

    With a SSI file, you make changes to the file and all the pages, the inclusion of which will update automatically and you need only download a SSI whenever you make a page.

    If you use a model, whenever you make a change, once again all children pages are updated, but you need to download * all * changed pages.

    I hope this helps.

  • Change to the underlying model does not update display AdvancedDataGrid

    I'm working on a project of Cairngorm MVC. A part of the application has an AdvancedDataGrid ("ADG") with two levels of available drilling - we will call the highest level 'States' and the 'cities' of second level. The default is 'States' only - the top-level nodes are closed. When I add a new 'State' to the underlying model, it appears correctly in the ADG. However, when I add a new 'city' to the 'State' that has been created, the open node icon is not displayed, even if the data is there. I know that the data is there, because when I click to open another node, the icon appears suddenly to the top-level node, that I just created. I can't understand why this is happening or how to fix it. I need to open the node icon to display when I add a child to it.

    I tried the validateNow() and invalidateDisplayList() on the ADG methods, but they do nothing...

    Please make suggestions.

    have you tried invalidateList?

  • Activation XP to replace the same brand and the motherboard model

    The PC in question had an OEM of XP without CD installation.  I have a good COA sticker. I've had damage to the motherboard as a result of a power of 250 BestTec supply failure. After a new PSU, I replaced the motherboard with exactly the same brand and model was original.  This was done in good faith, based on KB824125 which States that this should not need a new license.   However, now I can not find a way forward so that Microsoft "reactivate".   How can I get the activation?

    Additional details:

    All the files on the hard drive are OK, including Windows XP. The BIOS works fine.

    When I try to start Windows, he says that activation is required.  Activation of the Internet requires Windows, so that leaves me with activation by telephone.  50-digit ID is reported as invalid, and the automated system hang up.

    KB824125 seems to fix my problem and specifically says: "If the motherboard is replaced due to a fault, the user doesn't have to acquire a new license of operating system of the computer. The replacement of the motherboard must be the same brand and model or [options]. "There is no statement as to how to apply it.

    When I go to eMachines, they indicate very correctly the warranty is over and ask that I go to the web site of the software publisher.

    When I called Microsoft, I am led down an automated tree that ends with the possibility of buying support.

    I fixed the PC, and now my software appears as illegal.  Can someone tell me which way in the maze will solve this problem?

    I'd be happy to send the old motherboard to Microsoft, if that's their problem.

    You can try the phone activation - this time, when the automated system asks you what service you need, do NOT - this should oblige the operator to pick up. They will help you.

  • Will I get my current phone, replaced by a new phone, because the iPhone 6 is interrupted?

    Hi, I ask this question because I wonder if Apple will replace my phone with a new phone, or if they will just replace an iPhone 6, because my phone has completely stopped working. I know it's a stupid question, but I'm asking you this, so I know what Apple will do.

    They will almost certainly replace it with another iPhone 6; they usually have replacements on the spot, but nobody on these cards can say with certainty. In case they are not, you will get a more recent version.

    My screen iphone6 is cracked and in my country, they can only change the iphone with a new one and with a very high price. Is there anyway that I could replace just the screen?

    No, if you want to keep all rights to the service or support from Apple. Not to mention the fact that it then will be bork Touch ID and make the phone unusable if ever, you restore or update of iOS.

    Apple doesn't sell parts of the iPhone. There is no legitimate sources for replacement screens.

  • I need a new key for re install on a different motherboard, which is the same model?

    I currently I have Windows 7 Home Premium OEM installed on the computer, recently built, but have had problems with it because of a faulty motherboard, so I wonder if I can re install without problems, or if I need a new key because it it a different motherboard. The motherboard is an ASUS P8Z77 - V Pro. If I do not need a new key from Microsoft will be able to provide me with one, since it's just a computer, and I'm simply by changing a defective part?

    If it's a faulty motherboard, in such circumstances, you could try phone activation whenever you use a motherboard of the same model.

    My suggestion: buy a new machine because add them, cost more than buying a new machine itself and the result of may will not be big, UNLESS you are having another machine and use this machine for experimentation.

  • After its replacement by the new AM a LOV in the standard page stopped work (R12)

    I spread an AM in one of the standard Oracle applications Page. After its replacement by the new AM, a LOV in the standard page no longer works.
    Do anyone have a solution for this?

    Thank you
    Lou

    1. you can move this code to the controller.

    2. While doing the extension must also worry about the maintainability of the code.

    3. If you do not add this to the CO, create a new AM, specify this AM to a region on your page, now it will become nested AM.

    4. you can code for call PLSQL in this new AM.

    5. you can access this CO AM and call this method.

    I recommend to call the PLSQL Co.

  • Why mozilla firefox options synchronization replaces all the new password old password?

    When I sign in account twitter, linkedin, facebook and yahoo all sites informs me that you used your old password? I have change my password all the old almost 5 months before and after 5 months I used Firefox sync my new bookmarks update option, new name of connection sites and new passwords as well, but after that the sync option used, my new password replaced with the old password

    Maybe the 5 month period when this laptop principal was not connected to the Sync had a role to play in your problem. Sync is designed to synchronize Firefox data permanently, not to be started when you want to "data backup", as with a Cloud Computing service. And the password / feature connections has been changed just about this time, I remember well, then maybe who had a role to play in this last issue.

    1. my advice is to unplug all devices sync. 2. then, using computer laptop main with your latest data, reset your synchronization password. Will erase your data from the server, so you can get a fresh load of data to synchronize, and then to other devices when you connect again with the new password. 3 reconnect the computer main sync using the new password. 4. the next day reconnect another device using the new password. Check that connections data is now suitable for this device. 5. If it looks good, plug other devices one by one at a time by using the new password. And if you are using a "mobile version" of Firefox [Firefox for Android or Firefox for iOS] I would wait a few days to make sure that your data on the desktop / computer portable devices is good before you plug one of these devices.
