    Additional Hardware Requirements for Virtual Services Engines

    Before installing the Virtual Services Engine, ensure that you have access to the following additional hardware devices:

    • Serial console server or terminal server to assign an IP address after first powering on the appliance.
    • Uninterruptible power supply (UPS) for all appliances or systems running the Virtual Services Engine (VSE) software-storing data (such as consoles, event processors, or flow processors) to preserve your data during a power failure.

    We recommend that you install the VSE on your LAN to ensure that it can communicate with your applicable resources, such as authentication servers, DNS servers, internal Web servers through HTTP/HTTPS, external Web sites through HTTP/HTTPS (optional), the Juniper Networks update server by HTTP, Network File System (NFS) file servers (optional), and client/server applications (optional). Table 1 lists required port information on the VSE.
