1.4.5 USB Interfaces
The universal serial bus (USB) interfaces can connect multiple types of devices and
provide a higher data transfer rate than common parallel interfaces and serial
interfaces.
The F1000-E is completely compliant with USB 1.1. The USB interfaces on the firewall
provide important storage and security functions. For example, they provide large Flash
memory space for application programs, configuration files, and security VPN
certificates to establish secure VPN connections and secure the delivery of firewall
configuration files.
In addition, USB interfaces provide a backup CF card mechanism to make file backup
and restoration very convenient and reliable.
