ACCESSING THE CYBERSWITCHOVERVIEWThis chapter describes accessing your CyberSWITCH, which includes:• making proper connections• establishing an administration session• powering on the system• accessing Release NotesM AKING C ONNECTIONSThere are a number of ways to make a connection to the system, which include:• direct connection using a terminal• null-modem connection using a null-modem cable and a PC• remote connection using TelnetAll connections but the Telnet connection use the serial port (labeled COMMPORT or Console) onthe back of the system. The Telnet connection is made through the system’s ISDN line.DIRECT CONNECTIONThis is the simplest connection; you merely connect up an ASCII terminal to the Console port. How-ever, this method can only be used to configure or manage the system. To install or upgrade systemsoftware, you must use the null-modem connection.NULL-M ODEM CONNECTION TO A PCTo install or upgrade system software, you must use a PC or workstation to connect to the system.Since the CyberSWITCH does not have a CD-ROM drive, you must upgrade or install the softwarethrough an attached PC, UNIX workstation, or any device that meets the following requirements:• has a CD-ROM drive• provides an RS232 terminal program• has X-Modem communications capability (required for software upgrade only)• has ASCII transfer capability (required for SSB recovery)Any computer or terminal that meets these requirements and connects to the administration porton the system can operate as an administration console.
