OK so you've just got your new Cisco Rado switch.

You need to configure it.

So how do you configure a brand new Cisco router switch.

Now if it's a remote device and it's been configured correctly you could use a protocol such as telnet

or SSA each secure shell to remotely configure a device like this but generally with Cisco devices you

need to connect to the console port of the Cisco device and configure it locally first.

So how do you connect to a Cisco Radha or Cisco switches console port.

And this video I'm going to show you how to do that.

We're going to look at physical connections using the old traditional methods on an older laptop and

then how to connect to the device using a more modern laptop.

I'm going to show you how to configure the devices from the ground up so how do you connect to a Cisco

Rado switch.

I'm going to show you how to do that right now

Now traditionally a Cisco Rado switch would only have an RJ 45 console port these days fortunately they

now have USB ports.

So I'm going to show you firstly how to connect it to the device using an RJ 45 port and then I'll show

you how to connect it to the device using a USB port so much easier these days using a USB port.

So how do you connect your PC your laptop to the console of a Cisco right or switch in the old days

we used to use what was called a rollover cable like this.

This is known as a roll over cable because pin one on the one side goes to put eight on the other pin

two goes to pin seven point three to pin six all the way to point eight going to pin one.

So all the pins in this cable all rolled one to eight all the way to eight to one.

OK.

So what you would do is connect the one side to the console of the right or switch.

Don't make this mistake.

I've seen many people make this mistake.

Please don't make this mistake.

Don't connect the other side to the Ethan at port on APC.

You'll blow this port.

I've seen it happen too many times where people connect the Ethan at port to their P.C. or laptop and

then connect to the console board of a road or a switch and then it blows the port.

This is what's called an out of band connection.

We are not sending IP across this.

So TCB IP traffic is not going across this cable.

This is a serial port so you would in the old days need a serial port on your laptop to connect to the

router or switch.

So here I've got an old Toshiba laptop really good laptop for its time.

What you would need is what's called a D.B. nine to RJ 45 connector so DP nine converter like this RJ

45 on the one side nine because there's nine pins here female pins and you would connect to the serial

port of your P.C..

So what you would do is connect to the serial port on the one side and to the console port of your rod

or switch on the other side so something like this.

That's how you'd connect your rod or switch to your laptop now rather than doing it that way rather

than having a rollover cable like this.

Nine converter.

What they then did was create a cable like this.

Notice bolting DP nine female connect on the one side RG 45 on the other.

So this would allow me to connect directly to my laptop on the one side so nice connection on the one

side and then connect and then I'd connect to the rod or switch on the other side.

So RJ 45 on the one side that would go to the console port of the roto switch DP nine female connector

on the other side.

It's much easier to have a single roll over cable like this DP nine to RJ 45 than it was to have to

RJ 45 and then have to get a DP nine to RJ 45 converter or connector like this.

So that's the old way of doing things.

The problem is today's laptops don't have serial interfaces like this.

So how do you connect a modern laptop to a rod or switch.

If you don't have a serial interface here's a more modern laptop ISIS laptop one running Windows 10.

It doesn't have serial interfaces so I can't connect this serial cable to this laptop.

So what we had to do and things have got easier today put what we had to do in those days is use us

B to serial converter.

So what I'd have to do is buy something like this so here's an example.

You have to be careful with some of these.

Some of them don't work.

They were dodgy chips inside of them.

A lot of cases they wouldn't work but you'd get something reputable like this.

This would give you a male DB nine connector so you could connect the female console cable to this and

then this would go into your laptop.

So USP poured like that and then some of these cables out of the way.

And then you would have your console connection to the right or switch.

So something like this console on the right or a switch and then you would have us be on the laptop.

So that has been the way to do it for quite a few years.

But Cisco have started adding U.S. B connections to the writers of switches.

So here.

Notice this switch.

More modern switch has a U.S. B connector so much much better so much easier.

So what you would do is get a USB cable not micro USP standard USP and you would connect to a USB port

on your laptop.

That's a much easier way of doing it.

So there is a bit of history.

So the first part of the puzzle is you need to physically connect your laptop to a road or switch.

There are two ways to do it.

You can either use a traditional object 45 connector or you can use a USP connector.

In this video have now shown you both ways.
