You can perform network interface configuration using the TTY method or the diskette method. The TTY method requires that you establish a serial connection to your Netra Proxy Cache Server, as described in Appendix A of the Netra Proxy Cache Array (or Server) Configuration Guide.
See Section 2.3 of the Netra Proxy Cache Array Configuration Guide or Section 2.2 of the Netra Proxy Cache Server Configuration Guide for descriptions of the TTY and diskette methods of network interface configuration.
