3Com manual Software, Compatibility, SW/2500, can be used only with the CS/2500 and CS/2600

1-2 CHAPTER 1: OVERVIEW

■ 2 MB of memory

■ Ethernet attachment unit interface (AUI)

■	Support for parallel printers with Centronics™ interf aces
	Model CS/2500 has no diskette drive. This configuration is
	advantageous in environments where disk contamination is possible or
	where users are not allowed access to system software. The CS/2500
	boots over the network from a 3Com Remote Boot and Configuration
	Services (RBCS) server or a generic Trivial File Transfer Protocol/File
	Transfer Protocol (TFTP/FTP) server.
	Although some multiprotocol communications software packages
	include Network Control Server (NCS) software for backward
	compatibility, 3Com no longer provides technical support for NCS
	software or servers.
	Model CS/2600 has a 3.5-inch internal diskette drive. This model can
	boot either over the network or locally from the internal diskette drive.
Software	Models CS/2500 and CS/2600 communications servers use different
Compatibility	software versions from the earlier models CS/2000 and CS/2100. The
	software versions listed in Table 1-1, and other software with the prefix
	SW/2500, can be used only with the CS/2500 and CS/2600.
	Table 1-1 Software Compatible with CS/2500 and CS/2600
	Software	Label and Version
	TCP/OSI	SW/2500-TO-3270, 5.0 or later
	TCP/LAT/OSI	SW/2500-TLO-3270, 5.0 or
		later

In mixed environments, you can configure a CS/2500 or CS/2600 to emulate a CS/2000 or CS/2100 and therefore to be compatible with CS/2000 and CS/2100 software. For information on configuring this emulation, refer to “Emulating a CS/2000 or CS/2100” on page 4-12.
