Failover cable on F5 4000 pair

We have a new pair of F5 4000s in our data center and I am attempting to configure them as an HA pair. I have looked through the documentation but am unable to find how/where to configure this cable...

Thanks, I understand how I can create the HA VLAN, but still unclear about the failover cable. Just to be clear, it does not have an actual interface assignment on the F5, right?

    Correct. It used to be a DB9 port but it's RJ45 now on new models, but it doesn't appear as a data interface. You can do everything without failover cable as long as network failover is properly configured. Adding failover cable in conjuction to network failover will give you faster failover detections on your Standby unit so it can go Active quicker. Of course it is limited to 2 devices and they need to be close to each other due to cable length limitations. Salim
