If your laptop doesn't have a serial port, grab one of these : USB to Serial and Cisco Console Cable. This will allow you to configure the switch and add a management IP. After that you will be able access the switch via telnet. You can also set up ssh access which is preferred over telnet. There is plenty of instruction on how to do this, just google.
The best I've got right now is if you have a rollover cat5 cable, build a new cable which goes from

to

and then finally to

I ended up using this: http://www.amazon.com/gp/product/B005S2KPPU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
And then built a connector that should end up looking like:

I can't actually verify that this is correct, there was a time when i made one of these but I don't have it handy.

Warning: That Cisco 1921 is NOT a Linksys or Netgear router with a slick GUI that you can just keep clicking at until you get it to work.
If you were unable to figure out what a Cisco console cable is on your own, you're just not likely to figure out how to configure a device that complicated.
I encourage you to engage a small business consultant or a MSP or something.
> We need a console cable. What is a console cable?
You actually need two things:
> We need a cable running from the GE 0/1 port to the firewall

Not enough information provided.
First off, unless I'm mistaken, /r/homenetworking would be the right place for this thread.
The 1242 is not a router, it is a Wireless Access Point.
You need a Cisco Console Cable and a (USB-RS232 Adapter)[https://www.amazon.com/TRENDnet-Converter-Prolific-Chipset-TU-S9/dp/B0007T27H8/ref=sr_1_3?s=pc&ie=UTF8&qid=1486739466&sr=1-3&keywords=serial+to+usb] for your laptop.
Some basic google searching can lead you to various simple guides on Cisco's website for your intended use case.
It's a good switch to play around with to learn Cisco command line, and you will want to, because it may not even function correctly depending on the previous configuration. You will want to pick up a USB to serial, and a Cisco Console cable to at least factory reset it.
Use a regular console cable [RJ45 to DB9][1], coupled with a serial to USB [DB9 to USB][2].
The above is a better setup, and a bit more reliable than a straight up [RJ45 to USB][3] cable. (imo)

Hey OP, probably the best place to start is by getting your self a console roll over cable, you can go for the USB type or Serial DB9 (Be sure to shop around, these are just ones I found with a quick search) Note rollover cables are different from any other standard networking cable, so be sure to watch for that.
Once you have your console cable, you'll need a console program like Tera Term and depending on which port and type you have the rollover cable plugged into your comp, you need to select it and the baud rate for the cisco switch, it should be 9600 bauds. Providing there's no hiccups, it will go through the boot up process, you can then hit enter and either the switch will prompt you with
>Continue with configuration dialog? [yes/no]
or
>Switch>
These are the prompt you want, if you get the yes/no select no. If you just get Switch> then its good to go, all port are by default up
The ones that are bad news are
>Switch:
This means there's no ios on the machine, and you will need to find a good copy some how, including buying a functioning switch and copying over the ios.
>Password:
This means the previous owner never wiped their configs off it.
If either is the case feel free to pm me for more assistance.
Yeap. that's all I use with mine. If you're running windows, you just have to make sure you have the drivers, and check which COM port it registered as in Device Manager. Putty is free and works great.

That may work. I haven't used one like that personally.
I use something like this:

This gives you some flexibility to also use it with some network equipment that uses a db9 serial port instead of rj45
The Prolific Serial -> USB is what you use to plug into your PC.
Switch Console port -> Cisco Console to Serial cable -> serial to USB adapter -> USB port on PC
Cisco console cable: https://www.amazon.com/Cisco-72-3383-01-Rollover-Console-Female/dp/B005S2KPPU/
Prolific Serial to USB adapter: https://www.amazon.com/Sabrent-Converter-Prolific-Chipset-CB-DB9P/dp/B00IDSM6BW/
They have console -> usb cables, but YMMV on that.
Usually switches run RS-232 over RJ45, not Ethernet. We usually use a combination of a USB-Serial adapter and DB9 to RJ45 Rollover
But I also see now we have USB to RJ45 RS-232
Then we connect using
screen /dev/ttyUSB0 9600
