Chapter 2. Accessing the 8275-416You have several ways to physically make connection (connectivity) and access the8275-416 . Once connected, you will want to initially configure the IP information(either through the terminal interface or through DHCP or BootP), then choosewhich user interface you want to use to manage it. Therefore, all interfaces supportconfiguring the 8275-416 and obtaining information from it, thus providing greaterflexibility in how you manage your 8275-416 . This chapter explains the ways youcan connect to your 8275-416 .Connectivity MethodsThere are two connectivity methods used to physically access the 8275-416 :v Out-of-band connectivity, in which access to the 8275-416 is through the EIA 232port.v In-band connectivity, which is the ability to access the 8275-416 from a remotestation using the Ethernet networkTable 2 outlines the user interfaces that are available depending on your method ofconnectivity.Table 2. Connectivity Methods and Available User InterfacesConnectivity Method Available User InterfaceOut-of-band Terminal interface via the EIA 232 port(terminal directly attached, or remotelyattached to modem)In-Band v Terminal interface via Telnetv SNMP-based management interfacev Web-based management interfaceOut-of-Band ConnectivityOut-of-band connectivity lets you access your 8275-416 through the EIA 232 port. Itcan be either through a locally attached PC (personal computer) running VT100terminal emulation software, or through a remotely attached PC running VT100terminal emulation software.Locally Attached TerminalTo establish out-of-band connectivity using a locally attached terminal, make thephysical connections and set up using the following procedure:1. Attach one end of a null-modem cable to the EIA 232 port of the 8275-416 asshown in Figure 6 on page 12, and the other end to the COM port of your PC(see “Appendix C. Cable Pinout Diagrams” on page 79).© Copyright IBM Corp. 1999 11
