Hardware
This is the list of hardware you will need.
1.A pc or laptop running Windows 10 with minimum 15 inch display and 1920x1080 resolution.
2.Cisco router
Here is a list of models that can work, CISCO3845, CISCO3825, CISCO2851, CISCO2821.
The best option is the 3825 because it has a fast cpu and is not too bulky like the 3845. If you are speaking to a vendor, you can use any variant of these part numbers.
The part numbers differ based on the licenses installed. We can use any of them.
3.Network module part number NM-32A.
4.Cables; at least one CAB-OCTAL-ASYNC, max 4.
The CAB-OCTAL-ASYNC comes in different lengths, 1 meter, 2 meters, and 3 meters. The part number will differ based on the length.
You can specify this to your vendor.



There are other models of router, async cards, and cables. For example the 3900, 2900, and 4300/4400 series use the NIM-16a/24a modules.
We can use these as well but are a bit more expensive.
It is good practice to use RJ45 barrels connected to the RJ45 ends of the cab octal async cable and a regular ethernet cables attached to it.
This way the connectors are protected. It also allows you to extend the lenght of the serial/console line.
