1-2 CHAPTER 1: O VERVIEWn 2 MB of memoryn Ethernet attachment unit interface (AUI)n Support for parallel printers with Centronics™ interfacesModel CS/2500 has no diskette drive. This configuration isadvantageous in environments where disk contamination is possible orwhere users are not allowed access to system software. The CS/2500boots over the network from a 3Com Remote Boot and ConfigurationServices (RBCS) server or a generic Trivial File Transfer Protocol/FileTransfer Protocol (TFTP/FTP) server.Although some multiprotocol communications software packagesinclude Network Control Server (NCS) software for backwardcompatibility, 3Com no longer provides technical support for NCSsoftware or servers.Model CS/2600 has a 3.5-inch internal diskette drive. This model canboot either over the network or locally from the internal diskette drive.SoftwareCompatibilityModels CS/2500 and CS/2600 communications servers use differentsoftware versions from the earlier models CS/2000 and CS/2100. Thesoftware versions listed in Table 1-1, and other software with the prefixSW/2500, can be used only with the CS/2500 and CS/2600.In mixed environments, you can configure a CS/2500 or CS/2600 toemulate a CS/2000 or CS/2100 and therefore to be compatible withCS/2000 and CS/2100 software. For information on configuring thisemulation, refer to “Emulating a CS/2000 or CS/2100” on page 4-12.Table 1-1 Software Compatible with CS/2500 and CS/2600Software Label and VersionTCP/OSI SW/2500-TO-3270, 5.0 or laterTCP/LAT/OSI SW/2500-TLO-3270, 5.0 orlaterCS2500BookFile : Overview Page 2 Thursday, December 11, 1997 10:44 AM
