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.
