22 CHAPTER 1: P RE-I NSTALLATION GUIDELINESFor branch servers, all software services use eth0.CAUTION: The IBM X306m series servers treat eth0 as eth1 and eth1 aseth0 interface.Tools All of the servers in VCX systems arrive from the factory configured to usethe server’s serial port as the console connection. No keyboard or mouseconnections are enabled. To connect your PC to the VCX server, use a“Serial Cables” and run a “Terminal Emulation Program” on your PC.Serial Cables The null modem cable for IBM servers must have these characteristics:■ DB9 female connector on each end■ Sufficient length to reach from the PC to the VCX serverThe serial cable for 3Com V6000 (Analog) and V6100 (Digital) serverscomes with the server. One end connects to the serial port (marked 1010)on the connection module located in the middle lower portion of thefront panel.CAUTION: Insert and remove the cable connector very gently whenattaching the cable to the V6000 front panel. The connector is fragile andbreaks easily.Terminal EmulationProgramTo configure a VCX server, you must run a terminal emulation programon your PC that is connected to the serial port on the VCX server. Theprogram must be configured for the PC serial port you want to use(typically COM1 or COM2) and must have the parameters shown inTable 4.Table 4 Terminal Emulation Program ParametersIBM x306m or x346 Servers 3Com V6000 or V6100 ServersVT100 emulation mode VT100 emulation mode9600 Baud 115,200 Baud8 data bits 8 data bits1 stop bit 1 stop bitNo parity No parityNo flow control No flow control
