Maintenance Port
The maintenance port is the upper RS-232 connector on the ASC line module. The connector is
DB-25 (female). With serial line access via the maintenance port, the user interface prompt appears
once the dumb terminal is connected and the system is powered up. No special software is required
and the connection is made through a standard (not null modem) cable. This arrangement is shown
in Figure3-1. Entering commands via a dumb (or emulated) terminal is the only use for the
maintenance port. The maintenance port is configured for 8 data bits, no parity, one stop bit, and
9600bps.
