Maintenance Port
The maintenance port is the upper RS-232 connector on the ASC back card. The connector is DB-25
(female). The user interface prompt appears when a dumb terminal is connected to the maintenance port
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 Figure 3-1. Entering commands using
a dumb (or emulated) terminal is the only use for the maintenance port.
The maintenance port configuration includes 8 data bits, no parity, one stop bit, and 9600 bps.
