Bypass(IPS or TAP) network cross-connect the two RJ45 connectors electrically thus creating an extended Layer 1 network

 Thanks for your time and knowledge. I am trying to understand how bypass mode works in terms of cross connection. 
 Bypass mode:  network relays cross-connect the two RJ45 connectors electrically thus creating an extended Layer 1 network
 Let us focus on one connection  COM1 ---  3560 ---  ELFIQ (Link Balancer) ---- ASA. 
 Basically ELFIQ will be a bypass mode when power is gone. 
 The engineer told me that I have to put cross cable between ELFIQ and ASA5505 only which is "2" cable from below diagram. 
 So, it will be 
 COM1 ------(Straight)-----  3560 -----(straight)------  ELFIQ (Link Balancer) -----(cross)--- ASA.
 And he told me also that if there is no switch (in future). I need to put both cables as cross cables. 
 COM1 ------------- (Cross) ------------------ ELFIQ-------------- (Cross) ------------------ ASA5505
 I couldn't see any consistency from this bypass works because case 1 (with switch) and case 2 (without switch) 
 Is my understanding right like below? 
 case 1: straight - straight - cross : cross
 case 2: cross - cross: straight.

    If you have iTunes 11 on your Mac then you can enable the left-hand sidebar via option-command-S, that might make it easier to navigate.
    Connect the phone to your Mac and select it on that left-hand sidebar, and on the right-hand side of the screen there should be a series of tabs which you can use to select what to sync to the phone. If it's an audiobook then it should appear on the Books tab for selecting/syncing, and films will be on the Movies tab. When you've got the audiobook on your phone you should get an Audiobooks option in the Music app (you might need to tap the '...' tab at the bottom of the Music app to see it).

  • Two Catalyst 3560-X switches - anything required to connect the two together?

    I have one 3560-X switch currently in production. I bought another one to expand. Can I simply install it in the same rack and connect the two with a standard patch cable? Is a crossover cable required? Any special port configuration required? My "manual" for the 3560 keeps referencing the 3750-X. I don't have any "Stackwise" or "Stackpower" ports on the back. I'm sorry for posting such a simple question but what surprises me even more is I cannot find any information online in the last hour about this. I called support and they told me to come here.
    Thanks!

    It is better to use a cross-over cable so in case someone likes to get pedantic and hard-code the speed/duplex setting you won't panic.

    You have a 3560-X and like the 3750-X you should have StackPower.  StackPower will depend on whether or not you have a redundant power supply installed at either one of the units. If you didn't exercise this option, then you don't need to.  
    As to the accuracy of the documentation, yes, Cisco's been dropping-the-ball lately with documentation ... and from what I've heard, it's going to get worst as more and more people leave.  

  • HT2729 I have limited space on my new ipad. How can I limit the number of songs from my itunes on my imac from going to my ipad when I connect the two?

    I have limited space on my new ipad. How can I limit the number of songs from my itunes on my imac from going to my ipad when I connect the two?

    you can do this by keeping the external hard drive connected and doing the following
    -hold shift key down on computer while opening iTunes and a prompt will appear to choose a library
    -select choose library, iTunes should bring up your explorer windows where you can search for the external HD
    -after you find the external HD find the iTunes folder you just copied to it
    -after opening the iTunes folder look for the file that says iTunes library.itl or if you can't see that extenstion just look for a document looking thing in the iTunes folder that shows up as a database file
    -double click the database file and boom iTunes should load your library without having to copy it to the computer
    PS: do make sure that if you are going to do it this way, make sure that the external HD is connected at all times, because if you don't then you will get exclamation marks next to your iTunes songs
    double PS: if you are unsure how to find out if the iTunes library file is a database file just right click it and choose properties and under the type it should say database file
    hope this helps:)

    You can connect them in Target Mode http://support.apple.com/kb/HT1661 and then drag and drop from the iMac to the MacBook.

  • Hi I would like to show a presentation written on my macbook air on my television what is the best way to connect the two ?

    Hi I would like to show a presentation written on my macbook air on my television what is the best way to connect the two ?

    Much depends on the available connectivity  of your television.
    If it has HDMI input available, all you will need is a minidisplayport to HDMI adapter, and an HDMI cable long enough to place the Mac in the desired proximity to the TV. The adapter is avaialble from the Apple Store online.
    Provided the HDMI input on the television supports sound, and the model of your MBA supports it as well, make suree that your adapter is also supportive of sound, otherwise you will need to run separate cabling from the headphone jack of the MBA to TV sound input or external speakers.
    This is a somewhat specific answer to a question without any requisite detail. You don't indicate the model or type of inputs on your TV, nor do you indicate the model/generation of MBA you have.

  • How to connect the two virtual machine .

    I installed VM workstation and created two virtual machine .Please suggest me how to connect them internally each other though vm network editor.I want create RAC Setup for practice.

    NAT is the default adapter type in VirtualBox, which will work in almost any configuration and networking environment. Using the NAT adapter, the host system will establish connections on behalf of the guest OS. NAT requires that the corresponding VM guest adapter uses DHCP and cannot be used to provide any services unless you configure port forwarding (>1024) at the VirtualBox VM NAT adapter.
    Bridged networking is the most transparent adapter type, but requires a physical network adapter on the host OS, which is limited depending on the host system and hardware, e.g. wireless. It also requires that the user understands network and routing restrictions of the host system in case of using the interface to communicate between the host and VM. A combination of host-only and NAT may sometimes be necessary to allow the VM to connect to the internet and allow the host to communicate with the VM guest OS.
    Btw, the host-only adapter IP actually works on behalf of the host OS and can be used to allow the VM to access the host system. So if Internet is not required, the NAT or bridged adapter are not required. I'm not sure if many people realize that, since it's not really mentioned in the documentation. So if you use the host-only adapter, simply use the host-only IP instead of the host system real IP to connect the VM to the host OS.
    I also switched to VirtualBox a couple of years ago, mainly because it provides more VM hardware options, is free and because of the ability to manage multiple virtual machines and group them together. I have about 70 virtual machines for testing and evaluating configured on my home computer. I also like the option in VirtualBox to clone a VM based on a Snapshot.
    VMware provides a Virtual Network Editor in VMware Workstation (KB 1018697), which allows to customize any of the existing virtual network adapter or add new ones. The available technologies under any Type 2 hypervisor are very similar between different products:

  • HT4889 Do I connect the two macs with the ethernet cable or do I have to connect both from the ethernet cable to the modem/router

    Do I have to connect both macs directly with an ethernet cable without network connection to be able to transfer files/apps from the old to the new as I have tried migrating on the network without success.

    They can be connected directly or via an existing network. Turn on File Sharing for the computer that will be sending files.
    Using Migration Assistant will work best if the two computers are connected via Firewire cable. This assumes both computers have Firewire ports.

  • I want to use my Macbook Air 2011 as an external disk for my iMac 2011. I connected the two with a Thunderbolt cable and when starting the MacBook Air I pressed "T" and it worked except with Office documents. Can anybody help?

    I want to use my MacBook Air as an external disk to my iMac. I talked to Apple care and we solved it by connecting a Thunderbolt cable between the two computers. I then turn on the MacBook Air while pressing the "T" and it works. I can sit and work on my iMac and grab/change/save the files that are in my MacBook Air EXCEPT for the Microsoft Office files. I called Microsoft and they can't solve it. They say it might be a problem with the Thunderbolt cable. Has anybody have this problem?
    Both computers are 2011 and they both have Office 2011.
    Thanks in advance,

    For Word it says "Word cannot open this document. The document might be in use, the document might not be a valid Word document, or the file name might contain invalid characters (for example, /)"
    For Excel it says "the file could not be found. Check te spelling of the filename, and verify that the file location is correct. If you are trying to open the file from your list of most recently used files on the File menu, make sure hat the file has not been renamed, moved or deleted.
    I tried this with many different documents, and I always get the same message.

  • Mac mini and the powerbook, connecting the two

    Hi Everyone,
    I'm currently on the move, so the convenience of portability is extremely important.
    I'm a PowerBook user, with only little remaining hard drive space to spare. But, I also have an external hard drive to ease the matter. Now much of the space on my PB has been taken up by applications, but a large sum has also been used up by music. And by way of preference, I would rather not have to turn on my external in the event that I want to listen to music, which, really, is everytime I'm on my computer. So I'm looking to free up some space on my PB, which has lead me to consider a Mac mini. Whereas the PB would serve to house all my work applications and the external for all my work files, I anticipate that the mac mini would house all my music and other non-work related files.
    But going back to the issue of portability and convenience, I wouldn't want to have to lug around a keyboard and monitor with the mini, and which that in mind, I was wonder if it's decently possible to connect the mini to my PB, and effectively running the mini and all its applications from my PB.
    Thank you all.
    Regards,
    Jeremy

    Thank you for the facts and suggestions everyone. With all the information gathered, I've arrived at the following.
    So, I do have an external, as mentioned, but with all the sensitive data on its drives, I'd rather not have to turn it on whenever I feel like listening to music. I normally power it on three-four times a week to work on my projects, and after each respective session, I turn it off, concerned that it may possibly overheat.. or break down, as it's happened to me before with another external, a few years back.
    And I've come to agreement with you all, in that the mini with its current specs, isn't the most cost-effective and portable path I could take, with particular regards to my on-the-go lifestyle.
    And I would rather not have my PB opened up at this point... then it occurred to me... my iPod. I'm currently at the office at the moment, so I'm unable to test this out, but is it possible to run music off the ipod through the PB's speakers, while it's (obviously) connected to the PB? Or I suppose I could wait for Apple's iPod Hi-Fi.
