32 Preparing for installation553-3001-230 Standard 10.01 September 2007The Web clients operate as thin clients connecting directly to a Web server running onthe TM 3.0 server. All operations performed using a Web client are executed on the TM3.0 server. The TM 3.0 server requires connectivity to the ELAN subnets of the systemsmanaged.TM Windows and Web client require that an administrator account is logged on to theserver at all times, because the server uses the identity of the logged-in user for access.To allow TM 3.0 client access without logging in to the server at all times, please seeProcedure 50 “Allowing TM 3.0 client access without constant server log in (optional)”on page 221 for Windows 2000 and Windows 2003.Typical client-server architectureThe TM 3.0 client is a thick client that runs on a Windows PC. It does not operate in atraditional client-server model. Rather, the TM 3.0 client runs similar software to thatrunning on the TM 3.0 server. The TM 3.0 client communicates directly with themanaged systems, and therefore:• requires connectivity to the ELAN subnets of those systems• must be operational at the time any operations performed on the client are scheduledto run• if a site or system defines a serial profile for Station Admin, physical serialconnections must be present between the switch and the server, and between theswitch and the client PCs. Communications profiles are defined on a site/systembasis and are shared by a server and its clients.TM 3.0 hardware requirementsRefer to "Appendix A: TM 3.0 engineering guidelines" for more information about TM3.0 hardware requirements.Use correct informationThe information in this document is subject to change. For the latest systemrequirements, see the TM 3.0 General Release Bulletin.Ask the network card manufacturer about the type of network card and the availabilityof the required software driver.Response-time testing is based upon the recommended configuration, not the minimumconfiguration. Response-time performance is supported only on the recommendedconfiguration.
