Additional Hardware Requirements

 

Before installing your Juniper Secure Analytics (JSA) systems, ensure that you have access to the following additional hardware components:

  • A serial console.

  • To make sure that your JSA data is preserved during a power failure, we recommend that all JSA appliances or systems running JSA software storing data (such as Consoles, Event Processors, or Flow Processors) be equipped with an uninterruptible power supply (UPS).

We recommend that you install JSA on your LAN to ensure that it can communicate with your applicable resources, such as authentication servers, DNS servers, internal webservers through HTTP/HTTPS, external websites through HTTP/HTTPS (optional), the Juniper Networks update server through HTTP, network file system (NFS) file servers (optional), and client/server applications (optional).

Table 1 lists the port information for the JSA appliance.
