Hi I have a question.
I need to purchase an Expansion I/O module for my firewall.
So My company is adding one more ISP to the network.(There is already one ISP existing as outside interface). There is only one unused interface in the firewall. And I need to make one more connection(Port channel) going to the Core switch. So I need a total of 3 unused interfaces on the firewall. So i figured i need an expansion io module. Do I need to order 2 modules, for primary and secondary or just one. and is there any other items i need to purchase like power cable or something for expansion purpose.
Model is ASA 5525-X
Cisco Adaptive Security Appliance Software Version 9.8(4)12

as suggested official EOS, but you may some body has excess stock for your rquirement.
