How to create and install a Cisco EX90 console cable
- Gather the necessary tools
- 1–Soldering Iron
- 2–Solder
- 3–DB9 Enclosure. This one is being used here.
- 4–RS232 to TTL/CMOS converter. alldav.com sells the one used here. Cisco does not recommend or endorse Alldav specifically.
- 5–Cable w/RJ45 connector on one end Any type of cable with an 8P8C (RJ45) connector could used as long as pins 1,2,7 & 8 are connected. A standard RJ45 cable is being used here.
- You will also need wire strippers and possibly a screwdriver (depending on which DB9 enclosure you are using).

Step 4
- Install the Enclosure The EX90 console is now complete. The subsequent steps will cover making a console connection.

Step 5
- Make a Console Connection. Locate the Console Port. The EX90 console port is an 8P8C (RJ45) connection and is located on the bottom left corner of the unit.

Step 6
- Connect to the Console Port. Plug the 8P8C (RJ45) end into the console port. You’ll have to lean the unit forward to plug the cable in. It might be a little awkward to do alone. If someone else is available, ask for their assistance. As a last resort, lay the unit down. Ensure you have something soft (like a towel) to lay the unit on.

Step 7
- Connect the DB9 to a USB serial adapter and connect to a laptop/PC.

Step 8
- Configure a Terminal Emulator Session Configure your terminal emulator with the following parameters:
- Baud=38400
- Data bits=8
- Parity=none
- Stop bits=1
- Flow Control=none
- The example uses HyperTerminal for Windows; configuring your terminal emulator may vary slightly.
- You should now be at a login prompt when you connect with the terminal emulator.
