Sharp ARNC5J Service Manual - Page 2

[1] GENERAL The AR-NC5J is a print server with Falcon 32bit RISC chip, which automatically switches between 10BASE-T/100BASE-TX, conforming to network protocols of TCP/IP (Windows95, Windows98, WindowsMe, WindowsNT4.0, Windows2000, UNIX), IPX/SPX (Netware), AppleTalk (Macintosh), and NetBEUI (Windows95, Windows98, WindowsMe, WindowsNT4.0, Windows2000). The 32bit CPU, together with the automatic switch of 10/100BASE, provides high-speed process. This server allows to share printers in a wide range of network environments from a small-sized network by means of NetBEUI to a largescale network where two or more network protocols are intermingled. [2] ENVIRONMENT 1. Items required for connection to a network • Shield-type, twisted-pair cable (A cable of Category 5 is required for 100BASE-TX.) • Printer 2. Network computer • Windows95/98/Me/NT4.0/2000 (One of TCP/IP, NetWare, or NetBEUI must be available.) • UNIX • NetWare • Macintosh (AppleTalk must be available.) [3] MAJOR FUNCTIONS 1. Functions A. Automatic IP address setup by DHCP, BOOTP, RARP (1) DHCP/BOOTP The AR-NC5J, equipped with the DHCP/BOOTP protocols, allows to make setups related to TCP/IP in a network where a DHCP/BOOTP server is working. By enabling the DHCP/BOOTP setup of the AR-NC5J, the information related to TCP/IP which is valid in the DHCP/BOOTP server can be set to the AR-NC5J. • The DHCP protocol supported by the AR-NC5J basically conforms to RFC2131/2132. It conforms to Windows NT DHCP servers. • To utilize the DHCP function of the AR-CN5J, consult the network manager. (2) RARP The AR-NC5J, equipped with the RARP protocol, allows to make setup of IP address in a network where a RARP server is working. By enabling the RARP setup of the AR-NC5J, the IP address set in the RARP server can be assigned to the AR-NC5J. B. IPP conformity (TCP/IP) The AR-NC5J conforms to the Internet printing protocol (IPP Ver.1.0) which allows to print via the Internet. By using the IPP, it allows to print with a remote printer as well as Web access by HTTP. C. WWW browser The AR-NC5J, equipped with the HTTP server, can be accessed by a WWW browser to display the printer status or to change the printer setup. • For operations of HTTP, it is recommendable to use a WWW browser such as Internet Explore4.0 or later or Netscape Navigator4.0 or later. If another browser is used, it must at least conform to HTTP1.0 (RFC1945) or HTML2.0 (RFC1866). • To use HTTP, the TCP/IP protocol setup of the AR-NC5J must be valid and the IP address of the AR-NC5J must be set. 2.
