Connecting a Terminal to the Console Port
The console port is a serial RS-232 interface port that enables a connection to a terminal for performing hub monitoring and configuration functions. The terminal may be a PC or workstation running terminal emulation software, or a terminal configured as a Data Terminal Equipment (DTE) connection. Alternatively, this port can be connected to an external modem to enable remote dial-in management. You can use the out-of-band management program (described in the next chapter) over a standard modem connection. Or, by running SLIP protocol over a modem connection, you can use in-band management applications such as the Web agent embedded in the Agent Module or third-party SNMP network management software.
If you connect a terminal to the console port prior to powering on the hub, you can observe the progress and results of the power-up diagnostics as the hub goes through its initialization process.
The console port connector is configured as a male null modem connection using a male DB-9 (see Table A-1 for pinouts). A standard straight-through wired RS-232 cable is supplied with the Agent Module for connecting to this interface. This cable is shielded to comply with emissions regulations and requirements.
Console Port (Out-of-Band) Connections
To connect the ELH100-12/24TX console port to a terminal, do the following:
1.Connect a VT100 compatible terminal or a PC running a terminal emulation program to the console port (Figure 2-4). Use the null- modem cable provided with the Agent Module, or use a null modem connection that complies with the wiring assignments shown in Appendix A.
