FortiRPS 100 in the wild!

For those of you that have never seen one in the wild before, this is a FortiRPS (it’s the white box closest to us with the black and yellow cables coming out of it). It connects to the FortiGates and does exactly what you think a Forti Redundant Power Supply does……

One thing to note however is that you must cable it differently than the documentation as it is painfully wrong. If you cable it up the way the below image says……losing a power supply will cause you to lose a device. Not so redundant in that configuration eh? Look below, it tells you to put device one on ports 1 and 2 of the FortiRPS and device two on RPS ports 3 and 4. Ports 1 and 2 on the dang thing only goes to a single power supply. In order to actually have your device cabled for REDUNDANT POWER you need to switch the middle cables. IE, plug device one into RPS ports 1 and 3 and device two into RPS ports 2 and 4.

Stupid Fortinet

Don’t cable it like this, cable it like the bold section of the post (above the picture)
