Question

Serial console port instead RJ45 console port on Fortigate

Hi there,

 

I have couple FGT 3600C's which doesn't have RJ45 console port but has DB9 console port. I've tried multiple adaptors but can't get any output once these unit's once powered on. SSD's has been removed and status light never comes up just power light comes up green.

 

Just wondering if SSD removal could cause no Console output? I believe that if they powered on BIOS should still load and generate some output in my console session?

 

Maybe some one could point me to correct DB9 female to usb adapter? tried couple from Ebay with no luck and really need to setup these firewalls.

 

Thanks in advance for all suggestions/ ideas.

    hi,

     

    I attach a picture of a PDF from the old Knowledge Base article about DB9 to DB9 and DB9 to RJ45 pinouts.

    Reversing the common RJ45-DB9 cable won't work. I'd use a DB9-DB9 (both female) cable and a DB9-USB serial adapter. The DB9 cable sometimes was called 'null-modem' cable.

    Hi Ede,

     

    Thanks for your reply. Not sure I understand, what I will achieve if I use DB9-DB9 (both female) ? Wouldn't it be the same to plug in DB9-USB straight to the firewall?

     

    Thanks,

    Augustas

    Bought DB9-DB9 female cable and serial to usb adapter, can see that it's recognized as COM8 port on my laptop, but still not getting any from console session.

     

    Has anybody got experience consoling on Fortigate with serial console port? Don't want to believe that all 3 unit's are faulty especially when the green power light comes on, even if they faulty it should have some messages during boot up.

     

    Help please:)
