Fortigate HA cable

Hello,

Does HA cable between two Fortigates devices should be cross-over? or the straight one can work normally without any issues? 

Please anyone have a clarification about that for both types of cables UTP and Fiber

most of the FortiGate model interfaces are auto sense. In my production 2x FGT 501 and 2x FGT 800C uses straight cables without an issue.

I haven't used a fiber connection for HA yet but as both ports are identical I think fiber needs to be cross-over. All copper ports nowadays are GbE so they will auto-negotiate to become cross-over.

 

BTW, if you use port 14 and port 15 for HA, do connect port 14 to port 14 and port 15 to port15! NEVER cross HA ports!

Execuse me, I didn't get the point of how to connected HA since in out scenario all HAs are using two ports. You mean that i should connect FW1_port14 to FW2_port15 and vise-versa ?
