RJ45 pinout question ...

Yeah.. each and every Krone connector has its own connection pin layout.. it makes no difference .. as long as you strictly keep to the same pinout at both ends it will work fine..

The main thing is not to break or reverse the pairs.. and as long as you keep to the top or bottom color code as shown on the connector all will be well.

BTW one of the rules is to untwist an absolute min of cable.. to me it looks like you have untwisted a little more than needed.. keep the twists tight right up to the connector.

I assume that you have already tested the Ethernet cables and the Ethernet switch to make sure that they have been installed correctly.

Temporarily, disconnect the Ethernet cable from the Time Capsule

With the Time Capsule powered on, hold in the reset button on the back of the Time Capsule for 7-8 seconds and then release the button

Allow a full minute for the Time Capsule to restart to a slow, blinking amber light status

(This reset will not affect any of the data that might already be stored on the Time Capsule disk)

Connect the Ethernet cable to the WAN "O" port on the Time Capsule

On your Mac.....click on the WiFi menu at the top of the Mac's screen

Look for a listing of New AirPort Base Station

Click directly on AirPort Time Capsule

When you click on Time Capsule, that will start up the AirPort Utility setup "wizard". It will take a few seconds to analyze the network and then display a screen that will look like the example below, except that you will see your devices pictured

Type in a device name that you want to call the Time Capsule. You can use the same name that you used before if you wish.

Click Next

Watch the next screen very carefully to confirm that the Time Capsule will be set up to extend using Ethernet. This will confirm that the setup 'wizard" has detected the Ethernet cable connection to the Time Capsule and that the correct settings will be applied to the Time Capsule to extend the network using an Ethernet connection.

When you see the message of Setup Complete, click Done.

Now the Time Capsule is configured correctly to extend the network.

When the Switch1 is connected, the network slows almost to nothing and there is only my iMac connected/active on the network ... nobody else, no other iPad, no other iPhone or computer pulling data from the web. Only my iMac.

Is it possible that you previously had the Time Capsule set up to connect to the AirPort Extreme using a wireless connection?

If you did, you cannot connect an Ethernet cable to the Time Capsule.....because the Time Capsule is expecting a wireless connection......not an Ethernet connection.

In other words, if the Time Capsule was previously set up to connect using wireless and you simply connected an Ethernet cable to the Time Capsule, this will create a huge feedback loop and cause the Time Capsule network to crash.

The solution is to reconfigure the Time Capsule so that it will expect an Ethernet connection from the AirPort Extreme.....not a wireless connection. Post back if you need more help with this.
