Rollover cable and cross over cable

If I have OOB coonection from a terminal server to a router's console port, do I need to use rollover cable? how about if there's a patch panel betwn terminal server and the router, what cable should I use?

Start simple: if it was a term server and a router (via console), the octal serial cable goes directly into the console port of 2500, 2600 ... anything with an RJ45-style port..
If the console is something like a 6500 or 7500, then you'd need an adapter to a db25 connector.
If you were going directly from a PC (db9f)to an RJ45-style console, it's via a "rolled" cable (reverse the pin order, 1-8, 2-7,3-6, etc) which is most often a powder blue flat cable.
Now, if you need to extend those connections, anything that ultimately results in a "straight through" extension should work, if it's not too long.
So, whatever cable you'd normally use, with whatever "straight-through" assemblies you use to create an extension.
Good Luck

Use of straight through and cross over cable

hi,
according to icnd1, we need to use crossover cable to connect similar devices, lets say router to router or switch to swicth..
does this really matter? I mean, what if i use straight through cable to connect one switch to another?
thanks

Hmm, I don't know, does it really matter whether the link between devices can be used? (Laugh)
As the other posters have noted, many (newer) devices now support auto MDI/MDIX, but some don't. (Also, on devices that do, auto negotiation might be required to be enabled.) Some older devices sometimes have "special" uplink ports or manual method to switch the port's MDI/MDIX setting, and for those, too, you can use a strait through cable.
If none of the above, however, you'll need a cross over cable for "similar" device types, i.e. those whose tx/rx pins, on the port, are the same.
You need a cross over cable if both sides are MDI or MDIX (i.e. the same), straight cable if both sides are different.

Apple TV to PC. Cross-over cable or Ethernet?

My apple TV will plug directly into the pc with iTunes. Do I need a Cross-over cable or an Ethernet Cable? And What is the difference? Also How would I do this? Thanks in advance!

I got it in April this year... If I have no internet where I am using it, how do I authenticate it to play? Here I have no internet BUT I have no HDTV here... My house has no Internet but it does have an HDTV! Do I need an HDTV to connect it to iTunes to authenticate it? Or can I use my existing Dial-Up connection to do it.. By using my dial-up connection I mean like Connect it to my laptop, and then connecting my laptop to my dial up connection and opening iTunes and do it like that... Would that work?

Emac / PC cross over cable

Hello learned colleagues,
is it possible to connect an E-mac to a PC using their ethernet ports and a cross-over cable, (no switch)
I need to share files between both computers.
assistance appreciated
DB

Mac pro - powerbook g4 - networking with cross-over cable

I connect my powerbook to the Mac pro with a cross-over cable.
Personal file sharing is on both computers (both Mac osx 10.4.8)
Question 1:
While most of the time I can make the connection work I still don't understand the logic behind it.
Sometimes I connect and the connection works immediately, on other occasion I have to restart one of the macs or both to make it work.
Is there another solution then restarting?
Please enlight me on the subject.
Question 2:
My Macpro is connected to the internet (to a ethernet-router up the line, I can not pull another cable from the router because all the ports are busy).
My powerbook is connected to the Macpro with the cross-over cable.
Can I access the internet on my powerbook through the cross-over cable. I already tried the Internet Sharing on/off thing but I couldn't make it work.
Thank you all for sharing your knowledge on the subject.

Hello Eugene,
Just a quick note to let you know you and others know that you do not need a cross-over Ethernet cable to connect your Mac Pro to another device. The idea of using a cross-over cable is a hold over from bygone days of Ethernet ports and products that either were before the auto-mdix or just did not implement them to save cost. Auto mdix Ethernet ports (which the Mac Pro, and every current Mac computer has) are able to detect the type of cabling/connection, and auto configure the Ethernet port for the proper connection. This mean you can use a regular Ethernet patch cable and not be concerned if it is a straight thru or cross-over style.
As for sharing your internet connection using your Mac Pro, yes, it can be done, and the capability is included with OS X. You can find step by step instructions by accessing the Help menu in the finder and entering "sharing Internet" (without the quotes).
However, I would suggest you just buy an inexpensive Ethernet Switch, to use to expand the number of ports available from your router, and then run a line to your other computer.

I set up time capsule using a wireless 4g modem. it's been five hours and it still is saying making backup disk available (4.97 GB of 18.52 GB). Can I stop the whole thing, get a ethernet cable and start over to increase the speed of the backup?

I set up a new time capsule on a wireless 4g modem. I started the initial backup. It's been five hours and it still says "making backup disk available (4.97 GB of 18.52 GB)." Can I stop the whole thing, connect my computer to the time machine using an ethernet cable and start over to increase the speed of the backup?
Thanks,
David

oh i already did that. Im working on my imac and looking into this on my macbook. Was able to reproduce the issue again by trying to open TM. Locked out the finder again and had to restart. I checked the serial number and it was an early 2009 purchase with no coverage.
If you bought a Mac and got AppleCare with it, within 2 years of buying the TC, the TC is covered, too.
I have to admit that this $500 unit was the first to apparently junk out. The western digital that had my main data on that is my daily external that I store about 2TB of data on is still perfect and the new technology TM appears to already be cashed. Love the computers, not to big of a fan on the externals of the apple TV's. No life expectancy. Neither here nor there.
suggestions before I either get this looked at or scrap the HD on it and move forward.?
Reset the TC. See [Resetting an AirPort Base Station or Time Capsule FAQ|http://support.apple.com/kb/ht3728].
Try a "full reset" of Time Machine, per #A4 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).
If all else fails, take it to your local Apple Store or Authorized Repair location, they may be able to determine whether the disk is dead.
If it is, they might replace the TC for you. If not, they won't repair it, but if the electronics are ok, you can replace the HD yourself, if you want to. See http://discussions.apple.com/thread.jspa?threadID=2542983

Cross over cable

Do I need a cross over cable to connect my cable router to my Time Capsule via the WAN port on each unit ?

No.
Use a regular CAT5e or CAT6 Ethernet cable.

Not sure that I have selected the correct forum. Hope my questions are clearly stated.
Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter. TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices). It does not show Mail or Safari menus. System preferences' display "gathered" the Samsung and chose its resolution. I did not find a way to select the Samsung as my display.
In addition to having old hardware, we have Verizon FIOS providing internet and TV access. Is there any way to make this work for us? We would like to stream video (Netflix) and view shows from the Web. Do we need Apple TV to do this? Or is it not possible with our old iMac? My husband thinks that our Airport could be a factor.
Thank you

Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
There are, actually, many alternatives to choose from than just from a Mac.
You need to have or invest in a WiFi capable router for all of these examples.
Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
If you have a older Mac, like I have noticed many users do, then you have other options.
If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time, you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

Power button ribbon cable and media panel cable?

I'm confused about these cables. Do I need both the power button cable and media panel cable or just two of the same cables to get my sound ,power button and media panel working again?

I have a DV6000 btw.

Noughts and crosses over TCP

Hi,
I am doing project for uni of noughts and crosses game over TCP. This is my second project in Labview, I am autodidact. I know that in my program are a lot of this to make them better or to replace with more optimal sulutions (even notifiers), but I am on finish of the game, the next one will be better!
So the problem is in file client.vi, probably it is not complicated. Function Search and Replace String does not replace me anything. If You have some time (I suppose that not much than 10 min) check it please. Code is commented.
The file client.vi shoud only indicate the situation on the board.
Great thanks! I wish I could do something to repay You.
Best regards

Wireless charging cable and wireless data cable

Dear Apple,
If you can create the wireless charging cable and a wireless data cable, this will be awesome and easier because my sister is young and she always break my charging cable and I'm not gonna keep buying an charging cable.
If you please can create these, for iPad 4 or earlier.
These have to contains wireless range at lest 15 feet
Thank you for your support

1. This is a user to user forum, Apple is not here.
2. If its wireless, then there is no cable. i.e Wireless means without wires a.k.a no cables.
3. If you want to suggest something to apple use the Feedback link.

Two ACS4.0 box using win- can connect with cross over cable

Hi
we have 2 ACS4.0 box, internal replication is happening between ACS1(prim) to ACS2(sec) but not ACS2 to ACS1 why?
Also I need 1 suggesion, whether we can connect 2 ACS boxes through cross cable for sync.
At present it is connected with 2 diff cores(ACS1 to core 1 & ACS2 to core2) and cores are interconnected.
What is the normal practice.
Regards
Naga

Hi Naga,
The purpose of Replication in ACS is for the Primary Server to overwrite the secondary server's settings that you have chosen.
This is by design Replication is meant to be one way and not bi-directional.
The Cisco Secure ACS Solution Engine supports the operation of only one Ethernet connector at a time. Concurrent operation of both Ethernet connectors is not supported."
To get redundancy with any ACS - you need replication setup with TWO ACS, it is not
possible to setup a NIC failover in the same chasis.

Jagdeep

Im trying to hook up atv but the instructions say to select input and I cant get that far. I have plugged in the hdmi cable and the power cable and nothing happens. What am I doing wrong?

I am working with a hotspot only and maybe thats the problem?

Is this a cable modem? It has to be off for at least 20min and sometimes much longer before it will give up the old settings. You might even need to power down the cable modem overnight.
Tell us exactly what broadband you have with what ISP and exact model of modem..
The new TC cannot be setup without using the latest airport utility 6.3.1 or 6.3.2 and you need Lion - Mavericks to use it.
The computer also needs to have ipv6 setup to local link on whatever you are connecting with, wireless or ethernet.

VIA connection and Cross over connection using AWR MWO

Sir,
      I want to connect the top conductor to bottom conductor through VIA in AWR MICROWAVE OFFICE. I am able to generate the top and bottom condutor , but am not able to connect VIA from top to bottom conductor and also how we have to observe via ,top and bottom conductors using 3D view. I have shown the below figure name CROSS_OVER_VIA_HOLE, have to generate like this. I have shown also my generated top and bottom conductor EM structure and also 3D view

Most people just attach the .emp file to their message. Were you not able to do that? Please try again.
If you are new to EM simulation in the AWR design environment, please read our documentation on the EM Editor and watch this video.
1. Assuming this is a 2-sided board, when you define the dielectric layers, set them up as
     Air
    Dielectric
    Air
If you are using AXIEM and thick metal, add a second air layer to the bottom, and make the one just below the dielectric as thick as the conductor on the bottom side of the board. Conductors sit on TOP of the specified dielectric layer, and protrude into the dielectric layer above.
2. Just draw a circle using via material. Vias start from the top of the specified dielectric layer, and extend downward through as many dielectric layers as specified by "Extent".
3. In layout, you can overlap two shapes drawn on the same layer, and execute an exclusive OR (XOR) or Subtract command.
