HP LCS60 manual Connecting the System Console, Serial Port Optioning DTE/DCE

Installing the LCS60

Connecting the System Console

WARNING: Connect and disconnect cables ONLY when the power is off.

The LCS60 uses a system console to run diagnostics, receive error messages, and for administration. Configure the console as shown in Table 2-4.

Hardware

The LCS60 has four serial RS-232 ports which can emulate asynchronous DTE or DCE. Serial Port 1 is used for the LCS60 system console and operates at 9600 bps. Ports 2, 3, and 4 can be used to interface asynchronous terminals to the LCS60 UNIX System with Ports 2 and 3 providing 9600 bps operation and Port 4 providing 1200 bps operation. The system console must be an asynchronous ASCII terminal or PC (with terminal emulator). We recommend using a system console with scrolling capability. The system console can be connected directly, through a Lucent Technologies data switch, through modems (9600 bps), or through StarKeeper II NMS.

Connect the system console to the LCS60 using one of the four connection methods described in the following sections.

Serial Port Optioning (DTE/DCE)

Direct- and network-connected system consoles require Serial Port 1 to be optioned to emulate DCE for connection to an external DTE device (this is the default). If connection is through modems (DCE), Serial Port 1 must be optioned to emulate DTE. Refer to Figure 2-2 and Table 2-5 for optioning information; see Table 2-6 for DTE and DCE emulation and pin assignments for RS-232C inter- faces.
